Tire sizes table with wheel diameter. Visual tire calculator. Purpose of the Visual Bus Calculator

When choosing new tires for your car, first of all, you need to find out whether the copies offered by the seller are suitable for the parameters of a particular car. It is easy to make such calculations if you use the free online visual tire calculator 3D in the KAMTECH online store.

We offer you a wide selection of tires and rims for cars of various brands and models, and with the help of our best tire calculator you will quickly find your way and be able to make the right choice.

How to use a tire-disk calculator in the KAMTECH online store?

Take a few simple steps: select the standard size of your car, as well as the sizes of the new tires (rims) that you wish to purchase. Then click the "calculate" button. You will see the difference between tires (disks) and deviations according to various indicators: diameter, width, circumference, profile height, and so on.

If the visual online tire calculator 3D showed a discrepancy between the parameters of tires and wheels for the car brand, you should choose another model. Installing tires that are not recommended by the manufacturer can lead to improper operation of the speedometer, odometer or other electronic systems of the car (for example, ABS, EBD and others). Also, the handling characteristics of a car may deteriorate, which is quite dangerous, especially in winter.

If you install tires with a profile less than the standard one, the ride stiffness will increase, the driving comfort will decrease, and the load on the suspension will increase.

In other words, the usefulness of a tire calculator by car brand cannot be overestimated. It will save you time on the selection of tires and wheels, will not allow you to make the wrong choice and waste your money. Come to KAMTECH.RU - choose the right tires and buy them at a low price.

When the factory tires are worn out or if you want to install new tires, the next question arises: which type of tire will fit perfectly? Each car make and model is designed for individual tread and wheel parameters. All the necessary information is contained in the technical documentation or on the body of the vehicle - on the lid of the petrol tank from the inside.

The online store of tires and disks "MOSSHINA" has developed a special online tire calculator, with the help of which it is possible to determine the differences between tires in percentages, inches and centimeters.

It is imperative to find the correct rubber size. If you make a mistake and deviate from the factory standard sizes even by a few percent, the sensors will begin to distort the current information, fuel consumption will increase, and driving itself will become unsafe.

Tire calculator: tire comparison

With our electronic form, you can quickly and easily compare the circumference and diameter of a wheel, profile, tread. In addition, the tire calculator displays differences in suspension clearance, vehicle speed and engine RPM.

Tire calculator visual online: terms of use

In the upper left corner there are two forms for filling out:

• Previous size (standard size of the original tire);
• New size.

In the fields from left to right, you need to specify the tire width (millimeters), the height-to-width ratio (percent) and the rim diameter (inches). These figures are indicated on the tire profile. For convenience and clarity, an image of the tire and wheel is displayed, which can be turned on and off.

When filling in all the fields, the bus calculator will calculate the difference and provide all the information in the table on the right. If the difference is 3% or more, then we do not recommend installing such tires.

Instructions

Look at the nameplate in the driver's side doorway for the recommended tire size. Write it down on paper or memorize it. Find wheels of this size in a car dealer and use a tape measure to measure the outer diameter of the tire. Write this value down on paper. Drive the car into a hole and turn the front wheels out completely: first in one direction and then in the other direction. Measure with a ruler or tape measure the distance from the tire to the nearest structural member and write these values ​​down on paper.

When choosing your favorite tires, consider the diameter of the future rims, and, depending on the size of the future tire, choose the width of the rims. The required disc width is equal to the tread width. It may be easier to find a disc with a slightly larger diameter and the desired width. For example, take rims of 14 inches instead of 13 and pick up tires on them. This option will be even more advantageous in terms of durability, but at the same time more expensive.

Try to buy tires that are approximately the same dimensions as the recommended ones. For example, the manufacturer recommends tires with dimensions 175 / 70R13 86S. 175 is the overall width of the tire in millimeters, / 70 is the height of the tire's profile as a percentage of the width, R-13 is the mounting diameter corresponding to the diameter of the discs, 86 is the load factor, S is the speed index. It is worth noting that the overall width of the tire may differ from the tread width, so if you want a wider tread, then pay attention to this feature. Do not use tires with reduced load and speed ratios.

If you want to put R16 wheels instead of R13 on your car, find a rubber of a suitable width. Since 175mm R16 tires do not exist, it is more realistic to find 215mm and wider tires. Look at your notes and calculate how many centimeters you have left. Increasing the tire width by 1cm more than the recommended one reduces the measured distance between the wheel and the body by 5mm. Please note that it is not advisable to increase the wheel diameter by more than 3 cm, as this will lead to increased fuel consumption and a deterioration in the traction characteristics of the machine. Select suitable tires and measure their diameter with a tape measure. Compare with the recommended wheel diameter. If the excess of the recommended dimensions of the future wheel is within the limits of your calculated norm, you can safely buy the selected tires. The speed and load factor in this case will significantly exceed the recommended one, which will have a beneficial effect on the durability of the rubber.

With the help of a tire calculator, you can easily calculate how the outer dimensions of the wheel, the height of the ground clearance (clearance), the speedometer readings and other characteristics will change when tires with a different standard size are installed on your car. The calculator calculates all tire sizes in millimeters, and the vehicle speed in km / h.
And also the calculator will help to calculate the required rim width for a specific tire size.

How to use the tire calculator:

First enter the standard size installed on your car, and then the one that you want to install and click "calculate". The table on the right shows the results of the calculator's calculations.
Detailed information on tire marking in the section: tire marking.

We recommend that you only install the factory tire sizes that are specified in the operating instructions for your machine. Installation of non-standard sizes may void the dealer's warranty, as well as impair the performance and handling of the vehicle.

When converting tire sizes on a calculator, keep in mind that:

With an increase in the diameter of the rim (and, as a consequence, a decrease in the height of the tire profile, so that the outer diameter of the wheel remains unchanged), the load on the car's suspension increases, and comfort also deteriorates (the car will become noticeably stiffer).

With an excessive increase in the profile of the tire, the car becomes a "roll", it is less controlled and at critical values ​​of the height of the profile, the tire can begin to cling to the parts of the body and suspension of the car, which will subsequently lead to its destruction.

The difference in speedometer readings and real speed depends on the speed of the car, the higher the speed, the greater the difference

On the website of the online store, the site contains a convenient tire calculator that allows you to easily calculate the changes in wheel parameters when switching to a different tire size. With this online tool, you can calculate the outer measurements of the wheel, ground clearance (ride height), calculate the speedometer readings and other characteristics.

With the onset of the new season, every responsible car owner considers it necessary to change the tires in accordance with the season. The best option would be to install tires of the size recommended by the automaker for a particular car brand. In cases where this is not possible, deviations in diameter in the 2% range are allowed.

Replacing rubber requires a serious approach. When choosing new tires and wheels, it is necessary to take into account such indicators as:

• tire width,
• profile height,
• inner diameter of the wheel,
• permissible speed indices.

Incorrectly selected tires can cause malfunctions in the car electronics, increase fuel consumption, deteriorate driving comfort, and also cause problems during a vehicle inspection at the traffic police.

How to calculate tires?

To find the correct tire size, you need to use a tire calculator, with which the theoretical dimensions are determined. All measurements are carried out in millimeters, and the speed in km / h. To make a calculation, you must enter the parameters of the tires of your car in the appropriate line. Then enter the dimensions of the new tire and the rim to be installed. After specifying all the parameters in the table below, information about changes in the width of the tire and the height of the profile, the inner and outer diameter, the difference in speed (real and according to the speedometer readings) will appear.

What to look for when choosing a tire

• Installing tires and wheels of non-standard sizes can damage the tire itself, damage the wheel and reduce the performance of the car. When choosing a rubber, it is better to rely on the recommendations of the automaker.
• If the diameter of the wheel rim is larger, then the load on the suspension may increase. To maintain the same diameter of the outer wheel, the profile height indicators should be reduced.
• If you choose tires with a greatly increased profile, you need to be prepared for a loss in the quality of vehicle handling. The tire can rub against the body and suspension, causing rapid wear.
• Even with the smallest difference between the indicators on the speedometer and in reality, the error can increase significantly with increasing speed, which makes driving unsafe.
• Narrow or too wide rims can deform the tire. This, in turn, will lead to premature wear and poor performance.
