Any experienced motorist knows that for normal operation vehicle It is not enough to choose the necessary tire, install it on the wheels, balance and ride without the risk of accidents and premature wear. One of the most important actions to which the car must undergo is adjusting the collapse and convergence, that is, reconciling the position of the wheel in the horizontal direction to prevent excessive abrasability of rubber.

Many motorists who do not have sufficient driving experience often arises the question of why rush rubber with inner on the front axle. The reasons for this defect can be revealed several, and none of them depends on the other, in particular:

• Most frequent problems - These are malfunction and collapse of the wheels, and this may not be associated with adjustment, because their position is inconstant and from strong impact or vibrational influences it can easily change. In order for the driver to identify the problem with the consension and collapse, it can simply get involved on a straight roven road And for a few seconds let go of the steering wheel. If the car takes to the side - this is one of the signs of violation of this adjustment.

• Also, the problem of wear of the wheels on the inside may be in case of insufficient pressure in them, when the middle of the sole contact with the road is beaten, and the shoulder protectors, on the contrary, wear faster.
• If the motorist acquires a cheap replica instead of the original tire, then the probability of marriage in the manufacture of the wheel is great. Such a split, as a rule, causes an uneven distribution of masses, beating at speed, extra vibration And, most importantly, - uneven wear of the protector.
• Some cars are designed in such a way that when turning the wheels are slightly leaving, and engineers are deliberately resorting to such a reception in order to reduce the radius of the vehicle reversal. In such cases, the wheel has a contact stain with an expensive only one of the parts of the sole, which inevitably leads to wear of the tire on one side.
• If the tire is exploited by several seasons in a row, then the likelihood of its fatigue is large, which is why plastic deformations of hernia arise and, as a result, the destruction of treads from friction on the road surface.

If the motorist notices stirring rubber on its "iron horse", in most cases this can occur due to one or several of the factors listed above. Of course, the reasons may be more, for example, with a systematic overload of the car or in the case of its recovery after a serious accident with the deformation of the frame, however, it is generally incorrect whether the wheels becomes wither to the rapid wear of the tires.

How does the mechanism of wear of leading front wheels

At the occurrence of the above reasons, drivers begin to notice how eats rubber on the outside, and the physical process that occurs in such a situation is described below:

• The contact of the tire soles occurs uniformly throughout the clutch area, but only one of its parts, and the wheel can not only roll, without encountering the resistance path, but also to slip when overclocking, braking or turns.
• The solid coating acts on the protector as abrasive, and always causes the destruction of the micron layers of the tire soles during each trip.
• Considering that the uneven distribution of the contact surface causes an increase in pressure per unit area, the wear in this place occurs several times more intense due to the concentration of voltage at one point, which causes the so-called subsidence.

With the incorrect work of the main supervisor control systems, the driver can see what eats the inner part of the rubber on the front wheels after a few hundred kilometers of the mileage. This means that vigilance is never unnecessary, and constant tread height control over the entire area of \u200b\u200bthe tire sole helps to identify the problem in the early stages and prevent more serious breakdowns in the car.

The main reasons for rising rubber on the rear wheels

In the case when the motorist notices that he eats rubber on the rear axle, then the reasons can be both the same as those listed above and some other technological and operational features of the vehicle.

So, this defect most often arises due to the following factors:

• Of course, a disorder violation and collapsed as well as for the front wheels, one of the main reasons for rising rubber.
• Occasionally happens especially in relation to domestic cars Old models that the rear axle has dependent wheels, and it is a solid beam, check the position of the wheels on which and to adjust them is not possible. In such cases, the causes of the defect can be wounded in the non-projective bends of the most massive beam due to the contact of the car at the speed into a deep hole, and the problem will have to be corrected on the exhaust stand.
• During the tire of the wizard, irresponsibility is often showing, without using a dynamometric key when tightening nuts on the heels holding the wheel on the hub. In such cases, there may also be skewed and, as a result, eats rubber from the inside in front or from behind with all the ensuing consequences.
• Unlike front Bridge, for correct adjustment of the rear wheels, all control measurements are extremely important with full of tankSince it is located just from behind, and gasoline can weigh up to 50-70 kg. Thus, when adjusting the angle of inclination of the wheel with an empty tank during the nearest refueling, it may well be signed by the auto and the beginning of the wheels.

• The latter, which is particularly in dire with cars with a volume trunk, for example, SUVs, minivans or pickups - is the problem of overvolor, since drivers sometimes neglect the allowed curb weight of the car, the excess of which is often displayed in the state of the suspension and, as a result, affects the disorder of the wheels .

Why does the rubber approach from the inside of the wheel behind? Despite the fact that drivers often complain when eats rubber on the outside on the front axle, the rear axle is considered much more problematic in terms of its maintainability and the possibility of adjustment without significant spending.

Basic errors when adjusting the front wheels

Many experienced motorists faced such a problem when, after the next scheduled, the inner part of the front wheel is suddenly started. This is due primarily with violation of technology during adjustment of the convergence and collapse, since this procedure should be made on a special stand using appropriate equipment and professionally trained masters. If the procedure is carried out with violations, the result arises, called critical adjustments, which is expressed in the following criteria:

• Regardless of the class of a passenger car, when adjusting the collapse, it is desirable to withstand a negative angle index for the front axle, because the mechanism of rotation of the constant load from the engine leads them to equilibrium in this position.
• When setting up right corner convergence, that is, the positioning of the wheels in relation to the horizontal surface is necessary, on the contrary, to give the value only positive values \u200b\u200bto achieve the perfect balance while driving at high speed. It is such an adjustment that can ensure that the clutch stain with an expensive, if the wheel is not transferred relative to the regulatory values, it will accounterate to the entire area of \u200b\u200bthe wheel of the wheel, which in turn will provide the perfect traction effort and the transmission of the tire of all torque without any loss.

• The last important indicator, which many masters on tires neglected at all is Caster. This parameter is an angular value that characterizes the slope of the projection of the vertical plane in the wheel diameter relative to the perpendicular, lowered from the point of fastening the disk to the hub is strictly vertically. The importance of the correct positioning of this parameter is obvious, since the automatic return of the steering wheel in its original position is possible exclusively when providing proper adjustment.
• Accordingly, the correctly exposed steering thrust can ensure that the wheels will be exhibited strictly coaxially the trajectory of the movement, and during the ride there will not be the effect of their partial drift, which inevitably accompanied by erasing part of the protector.

For summer tires Critical adjustment is not so apparent due to the increased rigidity of the protectors and the operation of the wheel mainly throughout the sole of it on the ground. In case of winter rubber this parameter It often has a decisive effect due to the fact that the soft protectors are abruptly quickly and themselves have a greater depth.

So, after 10,000 km of run after improper adjustment of the convergence and collapse of the tires, there may be a difference in the height of the tread on the central and internal part up to 5-6 mm, which indicates the need to replace them, since such a defect is not subject to any recovery even after Leveling wheels.

If the driver notices one-sided wear on the sole of its tire, this should signal it about the need to appeal to the tireage in the near future. Otherwise, stirring rubber can lead to more serious consequences, up to the formation of hernia, or a sudden break of the wheel, which can be dangerous for the driver or its passengers, as the car loses control.

Why is the car eats rubber from the external and inside of the front wheels? Read and eliminate

Preliminary estimate

When the first signs of wear appear, it is necessary to eliminate the malfunction as soon as possible. Most of Reasons requires availability professional equipment. But, the initial diagnosis can be delivered independently. To do this, you will need to go to a flat and empty road. To put the car at a speed of 30 km / h, after which a few seconds throw the steering wheel.

If the car has not deviated from the rectilinear movement, then the problem is in tires. When cutting towards the cause of the wheel installation angles, suspension breakage, steering faults. Often listed problems are accompanied by various knocks.

Tire pressure. With a decrease in pressure in one of the wheels, high load falls on it. Because of this, the wear of this tire increases. When the first signs of rubbing on tires appear, first of all, the pressure in the wheels should be checked first. You can do it on any tire terminal or refueling. But, only need to take into account that modern pressure gauges do not allow one hundred percent accuracy of measurements. Therefore, it is advisable to check using 2 pressure gauges. This will increase the measurement accuracy.

How to determine the cause of rapid wear of tires by tire state?

A small number of car enthusiasts relate seriously to the tire wear process. When "rubber" loses its coupling qualities, it is customary to change it, but the exact replacement cycle is not so simple. Even supporting the right pressure in the car's tires during the entire service life, they can be worse much faster than the manufacturer predicts. This is due to the fact that there are certain malfunctions in the car, which lead to early erasing of the rubber tread.

In the drawing of the car wear of the car, you can learn how specifically the malfunction is available in the engine, suspension or other aggregates. After her elimination, the rubber will serve much longer, and the car will work in the right mode.

Strong wear from the inner or exterior of "rubber"

The most common problem among motorists is one-sided wear of the tire. "Rubber" can be stronger to braid from the inner or outside, and after a while it will become unusable for movement on the roads. Such a problem diagnoses the driver for the driver that the similarity-collapse was incorrectly performed on his car.

If the collapse is invalid, and the top of the wheel is shifted from the center of the car or towards the center of the car for several degrees, the wear of the tire with one of the sides will increase. In some situations, the deviation from zero collapse is necessary to the driver, for example, if he participates in races. Having exhibited a negative collapse, it is possible to improve the spat of the touch of the tire with the road surface, and the car is better in turns.

In urban conditions, it is necessary to install zero collapse, otherwise there will be problems with exchange rate stability, and even movement on a straight road will become unstable. To solve the problem with one-sided internal or external wear of the tires, it is necessary to carry out the gathering of the car.

Increased wear of the external and inside of the tire

When the protector automotive tire It is strongly wearing around the edges, but at the same time remains whole in the center, it clearly indicates problems with pressure in the "rubber" during the operation of the car. At low pressure in the tire, its inner part loses its road surface. This leads not only to increasing the wear of the tire on both sides, but also to an increase in fuel consumption, brake path and problems with handling.

Driving a low-pressure car in tires is dangerous for both the driver himself and for other participants road. If you regularly support tire pressure at one level, but still have a similar wear, we advise you to clarify in reference information to the car, whether the tire pressure indicator is correct. You have chosen. It is also recommended to change the pump for pumping a car tire, which can show incorrect results.

Dent on tires

Even the rubber surface of the tire can be covered with small dents that change the shape of the tire, and lead it to the state unsuitable for operation. At the edges of the tires form bugs and depressions, and the fault of this problem with the suspension.

When driving on the road, the car constantly jumps and lowers, and the suspension must absorb tires of the tires about the roadbed so that they do not appear dents. If there are problems with suspension or chassis, mitigating strikes about the road canvas may be insufficient.

Not every driver can be fully diagnosed with the suspension and chassis of the car. That is why in a similar situation it is better to refer to the specialists or try to replace shock absorbers. In most cases, they are to blame in the appearance of dents on tires.

Long diagonal dent and strong tread wear

This problem is relevant for the rear axle of the front-wheel drive car. Most often it occurs when a car It is operated in the cargo mode, that is, often transports the severity to which it is not designed. Also, such a problem can often observe taxi drivers.

If the car is not used as a means for constant transportation of gravity, but at the same time he has a similar problem, the reason for this is the wrong gathering. As a result, before installing new rubber on the car, it is necessary to check the gathering-collapse and set it to zero.

Overly strong tread wear in the middle of the tire

If the protector is almost completely erased in the middle, but at the edges of such a serious wear is not seen, it means that the problem is in driving on the roads at high pressure in the tire. Once again, check whether you really pumped the tire to the value recommended by the manufacturer of your car model.

Some experienced drivers argue that when traveling on a piled covers, gasoline is less consumed, and this is true. This is due to the fact that the car loses good clutch with the road, and his whole mass is shifted to the middle of the tire, pressing it to the roadbed. Such savings of gasoline will turn out frequent replacement tires because of their rapid wear.

It is worth noting that during the cold season, tire pressure may decrease due to weather factors. If you go on a trip to the "ice" tires, after a while after the start of movement, the air in the tires will begin to seriously warm up, and this can lead to exceeding the pressure recommended by the car manufacturer. As a result, the driver will receive a bad clutch with the road and wear of the tire in the middle.

To avoid problems with increasing tire pressure during the acceleration of the car in the cold season, before each trip, check the compliance of the pressure in the tedder recommended value.

Cracked tires

Another problem to which increased or reduced tire pressure can lead is the appearance of cracks. A shock of a border or pit is a stressful state for a tire, which is capable of carrying without damage at perfect pressure. If longitudinal cracks appear on the side wall of the tire, it means that it was used for a long time with insufficient pressure.

Also, small cracks may appear on the tire, and it can be said that the service life of rubber approached the end. In such tires, the chemical decay of elements begins, which allow it to maintain its properties. It follows from this that the operation of such tires is prohibited.

Hernia on the tire

When hitting a tire with high pressure on a solid surface, hernia may form inside it. This is due to damage to the inner layer of rubber, and it is not possible to notice the appearance of hernia. After a week or two or even more, hernia will manifest itself in the form of convexity on one of the side faces of the tire.

ATTENTION: Driving a car, on the tire of which there is a hernia, is extremely dangerous. When manifesting such a problem, it is immediately recommended to change the tire to the new one.

Extreme tread blocks got a convex wear

Diagnose a similar problem is the most difficult, since it is not visible. To determine the presence of convex wear of the side of the tread, it is necessary to spend your finger on them. It can be felt that the low edges of the protector block erased around the round shape, while the high edges, on the contrary, are pointed.

If a similar problem manifested itself on the car, you need to check the wheel bearings and ball hinges. It is worth noting that the extreme protector blocks can be caught on the same bus, while the rest will be in order.

The front edge of the tread is very worn

One of the most common problems is the wear of the front edge of the tread. The main problem is that most drivers believe that tires must be in a similar way to wear when working, but it is not. This wear indicates that there are some problems with the suspension. Most likely we are talking about the malfunction of ball supports or silent blocks.

The diagnosis of such a problem is possible only "to the touch". To do this, it is necessary to spend your hand along the edges of the tatterator. If some of the teeth are sharper than others, then the problem is present.

"Fortune" on the tire

If on automotive tire There are separate zones that are won stronger than the others, they are called "propellas" or spots. Most often, such spots manifest themselves on cars drivers who love sharply accelerate and brake. With rare (including emergency) braking, if there is no car aBS system, Wheels are blocked, and the car slips on the tire on the road to the ground. Slide leads to an increase in tire temperature and its instant wear.

In addition, the stains on the tires of the car may appear if it costs for a long time. With a long parking lot on a separate segment of the tire accounts for the entire weight of the car. Because of its structure, it can over time to deform.

Top 5 reasons why eats rubber

Car tires, like any thing, has its own definite resource and threshold of strength. Therefore, it is not surprising that with the intensive use of the car, rapid rubber wear occurs. Wear can be observed on any axis and side of the car, where there is any malfunction or violation. The normal life of tires within 4-6 years, taking into account if all this period rubber was operated carefully and neatly.

Today I will find out for what reasons can rub the tires? Let us give the 5 most common causes.

1. The collapse of convergence.

Eating rubber can occur due to the uneven arrangement of the wheels in relation to the body. The collapse is responsible for the position of the wheel along the vertical axis, when the convergence is responsible for placing the wheels when entering the turn.

Why in case of incorrect indicators, after time it may start to sweep the rubber on all sides and on different wheels. For example, if the wear is observed on the inside, it means that too much inclination is made inside. Such positions of the wheels are called a negative collapse. Accordingly, if wear is the outer side, then this is a positive collapse. So the wheels are tilted in different directions. Also, with the wrong collapse, the rubber can sweep on one wheel from the inside, on the other with the external one.

Why are the settings of the disorder broken down? There are several reasons:

Not timely control, long-term operation of the car on bad roads.

Barduer, pit and other potholes and irregularities.

After repairing the suspension, replacement of levers, silent blocks, steering tips, thrust, etc.

Wear suspension elements.

Run jet traction, there is a backlash in the bushings, etc.

Bent bridges, housing itself.

2. Low or high pressure tires

When operating the wheels with low pressure begins accelerated wear that part of the tire that is climbed and begged. At low pressure:

The rim begins to put pressure on the surface of the tire;

The tire structure begins at the edges.

That is, it is clear, with insufficient pressure, the side part of both internal and from the outside is often wearing. With an excess of pressure, respectively, the wear will be observed in the middle of the tire.

3. Pressure unevenness.

Frequent reason for those motorists who do not follow the machine and pressure in wheels in principle. The irregularity of the pressure of the wheels on the same axis almost always leads to the wear of one side or another, depending on the operating conditions. For example, on the right front wheel Pressure 1.5 Ba, on the opposite of him already 2.0 ba. That is, there is a difference, which means that uneven wear occurs. In such cases, often the car begins to "lead" into one of the parties, as a rule, where less pressure. There is also a "zhor" rubber.

4. Incorrect storage of tires in the summer or winter season. It is known that one to another should not be stored, especially if they are stored with dressed discs. Under the pressure of weight, the tires will be bombed into one of the parties. After a long "lying" in this position, the tires in most cases are no longer recoverable.

The correct storage method of the tire implies the installation of the wheels on the edge, that is, both on the wheel of the wheel, you need to store them. Periodically scrolling to not stuff. And even better, hang. If the tires are dressed on the discs, then you can put the plastics.

5. Aging, defects in manufacturing.

Now rarely, who uses tires longer than the shelf life, rubber, as a rule, comes in disrepair earlier from excessive operation. But, nevertheless, do not discard this reason. Check if there are no cracks, pores on rubber. Violation of tightness, all this directly affects the operation of tires. In case of damage to rubber, moisture is inserted inside the inside, which over time leads to the destruction of the metal sheath of the tire, the so-called cord.

According to the standards of manufacturers, the operation of tires whose age exceeds the ten-year term is prohibited.

Of course, this is not the entire list of reasons why rubber eating. There are still a number of problems, but they are less common. So:

Violation of the disk form, for example, after a strong blow on the curb, pit, etc.

Damage and malfunction suspension, for example, factory or acquired defect swivel fist, levers.

Damage to the rack, for example, beaten after a strong impact.

The hub bearing worn, of course, in this case should be strong, it will not be difficult to notice. But, after all, when checking the exclusion method, it will not be superfluous to check this node.

After hitting the tire from the disk, changed the landing geometry. On the "tire", you will shift the wheels yourself, scroll it if the tire has moved, it will be noticeable.

Change the geometry of the body. After a strong impact (accident) or turning the machine. You can only determine only a special tool. It is not rare that the cause of the violation of the body geometry is that the car is simply cooked from several parts. That is, the "designer", such common in the Far East, where cheaper to overtake from Japan, and then welding it "push" like normal car.

Conclusion

As a result, I would like to emphasize the importance of periodic diagnosis of suspension, checking the collapse of convergence, tire pressure. By the way, experts and manufacturers recommend checking the collapse on average every 3,000-5,000 km, given the road surface, possibly more often.

During the observed reason, she would save the premature zra rubber, and it will also allow, it may be possible to keep health, the driver and passengers. Good luck on the roads.

. Eats rubber on the outside front

Why eats rubber on the inside front or with an external on both wheels

Tires - material consumable and seasonal. Predict the degree of wear depending on the kilometer theoretical way is difficult. Almost everything depends on the rubber composition of the mixture. By years, the average service life is about 5-6 years. This is the border, upon reaching which the product will find cracks, and if they are presented, the risk of falling into a dangerous situation is great. However, the tire can lose proper appearance and much earlier.

Premature wear or eats rubber on a car on the outside: Treatment

The frequent cause of the short interval of the wheel replacement is uneven abrasion of the tread. Installation of a new set of tires rarely can fix the situation, since a malfunction - more often the result of incorrect setting of the machine and late care for it. Even the elementary procedure for controlling tire pressure is capable of preventing a late failure of the product of the tire industry.

Critical adjustments

Front suspension - a complex mechanism, but amenable to commissioning. Therefore, if it eats a rubber from the inside of the front, it is necessary first of all to analyze its current settings. Yes, and premature wear of the outer shoulder is also a reason for the inspection of the relative location of the front levers of the suspension.

Such a chassis device scheme is designed not only to optimize the wear resistance of the tires. First of all, other goals are prosecuted - an increase in the sustainability of the car and ensuring easy controllability. In the process of adjustment, it is customary to distinguish between three types of parameters:

• The collapse is the angle between the longitudinal plane of the wheel and the vertical axis or the position of the wheels relative to the road surface. Affects the area of \u200b\u200bthe contact spot with the road. Preferably a negative value.
• Alignment - the position of tires relative to the horizontal plane. It is required to compensate for the elastic movements of rubber parts when transmitting thrust on the wheels.
• Caster is the angle of inclination of the transverse vertical plane of the wheel relative to the vertical axis. Need to provide self-return steering when leaving the turn.

Accurate diagnosis

One-sided tread wear in most cases indicates incorrectness to set the above settings. In particular, the rapid erasing of the outer shoulders of the tire causes an increased positive collapse. In this case, the upper part of the tire is tilted from the center of the car. Universally correct adjustment does not happen - for each vehicle its set of conditioned values.

What to do if eats rubber from the inside front: Possible causes

Often there is a non-standard situation in the form of the presence of various wear in the tires installed on the same axis. Suppose the right wheel "eaten" from the outer end, the left - from the inner. The exact reason is an incorrectly carried out operation on adjusting the geometry of the relative location of the suspension elements.

True reason

A list of actions in the case when eats rubber on the outside front, partly relevant and when the internal shoulders is detected. When identifying increased abrasion of the treadmill from the inner region, the nature of faults to one of the groups should be attributed:

1. Side butchers are erased evenly - the adjustment of the corner of the collapse is incorrect.
2. Pilotless wear "Christmas tree" - Alignment does not correspond to the norm.

The variants of the combination of fixed species of the broken tread geometry are not excluded. Under such circumstances, the masters speak of the wrong setting and collapse, and convergence.
For your information. Not all machines are given the opportunity to adjust all three corners of the wheel location. If there are defects and the absence of the necessary adjustments, the reason should be sought in non-original and worn outboard components (silent blocks, etc. sleeves). You should not discount tires or incorrect chassis levers from the bills.

There are often cases when "eats" rubber from behind one of the parties. Worn silent blocks rear suspension - Probable cause of malfunction. However, tuning racks and various sorts of spacers can also cause deviations in the geometry of the used tires.

Actual questions

Why the gathering camber

Bad road Negatively affects not only the chassis components resource. Negative imprint it delivers them to their mutual location. Timely control of adjustments is required in the following cases:

• After a strong impact of the border, pit, potholes and other irregularities of the road canvase.
• At the end of the replacement of suspension elements.

Attention! The wear of the suspended components of the suspension structure also knocks down the installation angles.

The components are original and similarity-collapse correct: the tire is still unevenly wearing

It is likely that the bearing of the hub came into disrepair. If there is such a fault, it is difficult not to notice the backlash, shaking the wheel in different directions. If it is possible to deal with this ailment, then the incorrect geometry of the body is difficult to change. But due to the bent carrier part, it may well eat rubber from the inside of the back or in front of the car.

Premature wear does not satisfy the above signs

Above disassemble cases of asymmetric "eating" rubber products. The following cases of tread wear should be attributed to the symmetrical:

• On both sides: reduced tire pressure.
• CENTER: Increased pressure in wheels.

Often there are situations when one of the tires are workd faster on the front / rear axis, rather than others. The only argument in favor of such a state of affairs - miscellaneous pressure In tires located on one axis. As a result, the car leads and has increased friction in the wheel with a smaller amount of air.

Verdict

Probable faults causing the presence of uneven wear of the tread are:

• Eating rubber from the inside edge. If the "Christmas tree" is observed on the treadmill - the problem is in improper convergence; Uniform wear is the case in the false corner of the collapse.
• Eats rubber from an outdoor end - a positive collapse is to blame.

Settings of collapse-convergence are in the tolerance - to watch the following:

• The presence of wear of rubber suspension knots.
• The correct form of the flange rack.
• Compliance with the design of support bearings and various spacer requirements of the manufacturer.

The asymmetric geometry of the working part of the tire can also cause a damaged body. Another probable reason is a tangible backlash in the bearing of the hub.

Why is the car eats rubber from the external and inside of the front wheels? Read and eliminate

Many motorists are interested in why the car is eating rubber with the external and inside of the front wheels. This problem is quite common. Moreover, the complexity lies in the inability of the masters to accurately determine the cause of the breakdown, and it always lies far on the surface. Therefore, the owner is desirable to know the basic versions of the breakdown, leading to increased wear of the details. Some of the faults can be eliminated right in the garage. This will avoid unnecessary trips to the service, although no one has canceled the diagnostics. Knowing the reasons, you will be able to avoid mistakes from unrelaxed or inept mechanics.

Why is the car eats rubber from the external and inside of the front wheels? Everyone knows that car tires Over time wears, and, first of all, it concerns the front wheels. There are several factors that affect this process. Actually, not too active wear of the tires for the car is the norm. First of all, tires are erased from the inside of the wheel. This is explained by the presence of Castor. In theory, in normal conditions, wear on the wheel becomes noticeable after 2-3 seasons. With a more rapid wear, it is necessary to seek the cause of the problem.

Hydrometeo Center warned of reduced grain harvest / surfingbird

The crop of grain in Russia this year will be 15-20% lower than last year, the head of the Hydromet Center of Russia Dmitry Kikecthev believes. Last year, Russia collected a record 135.4 million tons of grain

Hydrometeocentre expects a grain harvest in Russia this year will be 15-20% lower than last year. About this, with reference to the words of acting director of the Hydrometeorological Center, Dmitry Kikekova reports Interfax.

"The prediction of the Hydrometeorological Center - Vintage this year for grain and grain-legumes is expected to approximately 15-20% below last year," Kikthev said.

Kikethev also recalled that in the first half of June in the North Caucasus, in Volga and South federal Districts Atmospheric and soil droughts were noted. According to him, strong precipitation, which passed in the last two weeks in some areas, was "distributed unevenly, very motley."

Nevertheless, now weather conditions for ripening grain in Russia are estimated by meteorologists as "normal" and "satisfactory". "That is, the situation is not alarming," he added, recalling that in 2017 Russia gathered a record for their crop history.

According to Rosstat, in 2017 135.4 million tons of grain were collected - more than in the history of Russia.

Earlier, the head of the Ministry of Agriculture Dmitry Patrushev said that this year the harvest is expecting a harvest within 100 million tons of grain due to drought in the southern regions of Russia. At the same time, according to him, the export of grain from Russia this year will be 40-45 million tons.

"About 100 million tons - we hope that such a grain volume we will collect this year. At the same time, it is necessary to clearly understand that the forecast for the future can be changed depending on how weather conditions will be formed, "said Patrushev in early July (a quote on TASS).

The minister noted that the situation with the forecast for grain regularly changes. "There will be an opportunity to collect more, of course, we will make every effort and do it," Patrushev added.

Tires are one of the most susceptible to wear of the parts of the car. But what to do if they wear unevenly. To begin with, it should be properly defined this non-uniformity of tire wear to determine its causes. How unevenly wear tires:

• at various places of the circle - at certain points of the tread, it is worn strongly (spots),
• on the various side of the tires - the outer, the inner side of the tire or its central area throughout the circumference,
• one tire is wears much faster than the rest,
• a pair of front or rear tires come into disrepair faster.

Let's now give the causes and consider the character of tire wear for each reason. Causes of these will consider from the most common to less common.

The tire is worn in the center or on the sides. The reason is insufficient or excessive tire pressure

Incorrectly exhaustable leads to the fact that their abrasion proceeds unevenly. Trying to identify this reason on specific worn wheels - a useless spending time. Pressure can change in each wheel in different ways, even if you always turn into all four wheels.

But this reason can be determined by the nature of the wear of the tread itself. The fact is that the untapped tire is known, it seems, and it's therefore, the sides of the working surface are extermined faster. But the pushed tires are erased faster, on the contrary, the central part, since, with overcall pressure, it is its pressure that pushes the most, as a result of which, the axis of the circle accounts for the most load.

The result of riding on the pushed (from above) and the untapped (bottom) tires

On the tire only certain areas are worn. Cause - deformed disk or broken wheel balancing

The deformed (cast, "eight", etc.) the disk can also often cause uneven wear of rubber. In this case, the wear will occur in certain places (spots) of the tread. If the disk "eight", then wear will be in the form of two stains: one on one side of the tire in a specific place, and the second is in the diametrically opposite place of the tire and on the opposite side. During deformation of the disk, the tire is wearing very quickly depending on the degree of deformation, of course.

Similar bus wear is subject to both the wheel imbalance. Although it happens much slower than with a deformed disk.

And in both cases, an additional symptom is on the steering wheel or throughout the machine. BUT visual inspection The worn wheel will help reveal this deformation.

Sometimes the reason for the increased wear can also be the rubber itself - its marriage in the form of a bunting metal cord. Cord can burst if the rubber has already been significantly worn out.

Only the inner or outer side of the front wheels is wearing. The reason is the collapse of the wheels

If the alignment of the front wheels got lost, then this means that your two front wheels are not parallel to each other. They either "closer" - look ahead, a little to the center of the projection of the direction, or inclined in one or another side relative to the vertical axis.

As a result, you get excessive wear of the rubber only the front wheels or on the inside or from the external one.

If a similar situation occurred with the rear wheels, then there is a bell beam (if available) or one of the failed (perhaps also curved) suspension elements.

The outer side of the tires can also wear out due to a faulty silent block or ball.

Only one wheel flashes. The reason is something happened in the suspension or the brake clinic

If any component has been caught in your suspension, such as the flowing rack, it can lead to excessive wear of tires on this particular wheel. If any suspension item works incorrectly, the wheel will bounce anymore either will be hard to pass the road irregularities. This creates additional friction on this bus, which makes it makes much to reduce its service life and the tire tread state.

Here, as a rule, uniform wear is only tires only on one wheel.

And now imagine that you drive around the whole day with a slightly pressing the brake with your foot. This is what it is like if the clinite is some braking component, such as a caliper (its piston). This is usually only on the same wheel, and it is beaten faster because of this (uniform wear occurs).

Only the front wheels are wearing. The reason - something happened in the steering

Almost every part of the steering system may also lead to tire wear. But the speech here will only be about the front wheels, and the nature of wear can be completely different: both spots and one side of the tires along the entire circumference of the tread.

A small number of car enthusiasts relate seriously to the tire wear process. When "rubber" loses its coupling qualities, it is customary to change it, but the exact replacement cycle is not so simple. Even supporting the right pressure in the car's tires during the entire service life, they can be worse much faster than the manufacturer predicts. This is due to the fact that there are certain malfunctions in the car, which lead to early erasing of the rubber tread.

In the drawing of the car wear of the car, you can learn how specifically the malfunction is available in the engine, suspension or other aggregates. After her elimination, the rubber will serve much longer, and the car will work in the right mode.

Strong wear from the inner or exterior of "rubber"

The most common problem among motorists is one-sided wear of the tire. "Rubber" can be stronger to braid from the inner or outside, and after a while it will become unusable for movement on the roads. Such a problem diagnoses the driver for the driver that the similarity-collapse was incorrectly performed on his car.

If the collapse is invalid, and the top of the wheel is shifted from the center of the car or towards the center of the car for several degrees, the wear of the tire with one of the sides will increase. In some situations, the deviation from zero collapse is necessary to the driver, for example, if he participates in races. Having exhibited a negative collapse, it is possible to improve the spat of the touch of the tire with the road surface, and the car is better in turns.

In urban conditions, it is necessary to install zero collapse, otherwise there will be problems with exchange rate stability, and even movement on a straight road will become unstable. To solve the problem with one-sided internal or external wear of the tires, it is necessary to carry out the gathering of the car.

Increased wear of the external and inside of the tire

When the automotive tire protector is strongly flashes around the edges, but in the center remains the whole, it clearly indicates problems with pressure in the "rubber" during the operation of the car. At low pressure in the tire, its inner part loses its road surface. This leads not only to increasing the wear of the tire on both sides, but also to an increase in fuel consumption, brake path and problems with handling.

Driving a low-pressure car in tires is dangerous for both the driver himself and other road users. If you regularly support tire pressure at one level, but still have a similar wear, we advise you to clarify in reference information to the car, whether the tire pressure indicator is correct. You have chosen. It is also recommended to change the pump for pumping a car tire, which can show incorrect results.

Even the rubber surface of the tire can be covered with small dents that change the shape of the tire, and lead it to the state unsuitable for operation. At the edges of the tires form bugs and depressions, and the fault of this problem with the suspension.

When driving on the road, the car constantly jumps and lowers, and the suspension must absorb tires of the tires about the roadbed so that they do not appear dents. If there are problems with the suspension or chassis, softening strikes on the road canvas may be insufficient.

Not every driver can be fully diagnosed with the suspension and chassis of the car. That is why in a similar situation it is better to refer to the specialists or try to replace shock absorbers. In most cases, they are to blame in the appearance of dents on tires.

Long diagonal dent and strong tread wear

This problem is relevant for the rear axle of the front-wheel drive car. Most often it occurs when the passenger car is operated in the cargo mode, that is, often transports the severity to which it is not designed. Also, such a problem can often observe taxi drivers.

If the car is not used as a means for constant transportation of gravity, but at the same time he has a similar problem, the reason for this is the wrong gathering. As a result, before installing new rubber on the car, it is necessary to check the gathering-collapse and set it to zero.

Overly strong tread wear in the middle of the tire

If the protector is almost completely erased in the middle, but at the edges of such a serious wear is not seen, it means that the problem is in driving on the roads at high pressure in the tire. Once again, check whether you really pumped the tire to the value recommended by the manufacturer of your car model.

Some experienced drivers argue that when traveling on a piled covers, gasoline is less consumed, and this is true. This is due to the fact that the car loses good clutch with the road, and his whole mass is shifted to the middle of the tire, pressing it to the roadbed. Such savings of gasoline will turn into the need for frequent replacement of tires due to their rapid wear.

It is worth noting that during the cold season, tire pressure may decrease due to weather factors. If you go on a trip to the "ice" tires, after a while after the start of movement, the air in the tires will begin to seriously warm up, and this can lead to exceeding the pressure recommended by the car manufacturer. As a result, the driver will receive a bad clutch with the road and wear of the tire in the middle.

To avoid problems with increasing tire pressure during the acceleration of the car in the cold season, before each trip, check the compliance of the pressure in the tedder recommended value.

Another problem to which increased or reduced tire pressure can lead is the appearance of cracks. A shock of a border or pit is a stressful state for a tire, which is capable of carrying without damage at perfect pressure. If longitudinal cracks appear on the side wall of the tire, it means that it was used for a long time with insufficient pressure.

Also, small cracks may appear on the tire, and it can be said that the service life of rubber approached the end. In such tires, the chemical decay of elements begins, which allow it to maintain its properties. It follows from this that the operation of such tires is prohibited.

When hitting a tire with high pressure on a solid surface, hernia may form inside it. This is due to damage to the inner layer of rubber, and it is not possible to notice the appearance of hernia. After a week or two or even more, hernia will manifest itself in the form of convexity on one of the side faces of the tire.

Attention: Driving a car on the tire of which hernia is present, extremely dangerous. When manifesting such a problem, it is immediately recommended to change the tire to the new one.

Diagnose a similar problem is the most difficult, since it is not visible. To determine the presence of convex wear of the side of the tread, it is necessary to spend your finger on them. It can be felt that the low edges of the protector block erased around the round shape, while the high edges, on the contrary, are pointed.

If a similar problem manifested itself on the car, you need to check the wheel bearings and ball hinges. It is worth noting that the extreme protector blocks can be caught on the same bus, while the rest will be in order.

One of the most common problems is the wear of the front edge of the tread. The main problem is that most drivers believe that tires must be in a similar way to wear when working, but it is not. This wear indicates that there are some problems with the suspension. Most likely we are talking about the malfunction of ball supports or silent blocks.

The diagnosis of such a problem is possible only "to the touch". To do this, it is necessary to spend your hand along the edges of the tatterator. If some of the teeth are sharper than others, then the problem is present.

If there are separate zones on the vehicle with a car cover, which are more stronger than the others, they are called "propellas" or stains. Most often, such spots manifest themselves on cars drivers who love sharply accelerate and brake. With rare (including emergency) braking, if there is no ABS system on the car, the wheels are blocked, and the car slides on the tire on the road to the road. Slide leads to an increase in tire temperature and its instant wear.

In addition, the stains on the tires of the car may appear if it costs for a long time. With a long parking lot on a separate segment of the tire accounts for the entire weight of the car. Because of its structure, it can over time to deform.

Car tires, like any thing, has its own definite resource and threshold of strength. Therefore, it is not surprising that with the intensive use of the car, rapid rubber wear occurs. Wear can be observed on any axis and side of the car, where there is any malfunction or violation. The normal life of tires within 4-6 years, taking into account if all this period rubber was operated carefully and neatly.

Today I will find out for what reasons can rub the tires? Let us give the 5 most common causes.

1. The collapse of convergence.

Eating rubber can occur due to the uneven arrangement of the wheels in relation to the body. The collapse is responsible for the position of the wheel along the vertical axis, when the convergence is responsible for placing the wheels when entering the turn.

Why in case of incorrect indicators, through time it can start sweating rubber from all sides and on different wheels. For example, if the wear is observed on the inside, it means that too much inclination is made inside. Such positions of the wheels are called the collapse. Accordingly, if wear is the outer side, then this is a positive collapse. So the wheels are tilted in different directions. Also, with the wrong collapse, the rubber can sweep on one wheel from the inside, on the other with the external one.

Why are the settings of the disorder broken down? There are several reasons:

Not timely control, long-term operation of the car on bad roads.

Barduer, pit and other potholes and irregularities.

After repairing the suspension, replacing the levers, steering, traction, etc.

Wear suspension elements.

The jet thrust bet, there is a backlash in the sleeves, etc.

Bent bridges, housing itself.

2. Low or high tire pressure.

When operating low-pressure wheels, the accelerated wear of the tire part, which is climbing and begged. At low pressure:

The rim begins to put pressure on the surface of the tire;

The tire structure begins at the edges.

That is, it is clear, with insufficient often wears the side, both from the inner and from the outside. With an excess of pressure, respectively, the wear will be observed in the middle of the tire.

3. Pressure unevenness.

Frequent reason for those motorists who do not follow the machine and pressure in wheels in principle. The irregularity of the pressure of the wheels on the same axis almost always leads to the wear of one side or another, depending on the operating conditions. For example, on the right front wheel, the pressure of 1.5 Ba, on the opposite 2.0 ba. That is, there is a difference, which means that uneven wear occurs. In such cases, often the car begins to "lead" into one of the parties, as a rule, where less pressure. There is also a "zhor" rubber.

4. Improper storage of tires in the summer or winter season. It is known that one to another should not be stored, especially if they are stored with dressed discs. Under the pressure of weight, the tires will be bombed into one of the parties. After a long "lying" in this position, the tires in most cases are no longer recoverable.

The correct storage method of the tire implies the installation of the wheels on the edge, that is, both on the wheel of the wheel, you need to store them. Periodically scrolling to not stuff. And even better, hang. If the tires are dressed on the discs, then you can put the plastics.

5. Aging, defects in manufacturing.

Now rarely, who uses tires longer than the shelf life, rubber, as a rule, comes in disrepair earlier from excessive operation. But, nevertheless, do not discard this reason. Check if there are no cracks, pores on rubber. Violation of tightness, all this directly affects the operation of tires. In case of damage to rubber, moisture is inserted inside the inside, which over time leads to the destruction of the metal sheath of the tire, the so-called cord.

Cracks on rubber

According to the standards of manufacturers, the operation of tires whose age exceeds the ten-year term is prohibited.

Of course, this is not the entire list of reasons why rubber eating. There are still a number of problems, but they are less common. So:

Violation of the disk form, for example, after a strong blow on the curb, pit, etc.

Damage and malfunction suspension, for example, factory or acquired defect, levers.

Damage, for example, bent after a strong impact.

Worn hub, of course, the backlash should be strong in this case, it will not be difficult to notice. But, after all, when checking the exclusion method, it will not be superfluous to check this node.

After hitting the tire from the disk, changed the landing geometry. On the "tire", you will shift the wheels yourself, scroll it if the tire has moved, it will be noticeable.

Change the geometry of the body. After a strong impact (accident) or turning the machine. You can only determine only a special tool. It is not rare that the cause of the violation of the body geometry is that the car is simply cooked from several parts. That is, the "designer", such common in the Far East, where it is cheaper to overtake from Japan, and then welding it to "push" like a normal car.

Conclusion

As a result, I would like to emphasize the importance of periodic diagnosis of suspension, checking the collapse of convergence, tire pressure. By the way, experts and manufacturers recommend checking the collapse on average every 3,000-5,000 km, given the road surface, possibly more often.

During the observed reason, she would save the premature zra rubber, and it will also allow, it may be possible to keep health, the driver and passengers. Good luck on the roads.
