Tire calculator. Recalculation of the tire size Determine the outer diameter of the tire
When choosing new wheels for a car, the question often arises whether I should put wheels larger or smaller, or in order to improve the appearance of the car or reduce the cost of buying tires and wheels. But the most important question arises, will the wheels fit my car and how will its characteristics change. You can understand whether the wheels will fit on the gas tank cap or the side stand of the car (photo 1). Or find your car in our directory of applicability of discs to cars, and see the tires recommended by the factory. But it often happens that you can put other tires that are not officially approved by the factory.
In this case, the main thing is to understand how the speedometer will change, i.e. the speed of the machine, as the outer radius of the wheel will change. The clearance (ground clearance) will also change. It is not recommended to go beyond the values of factory tires by more than 2-3%. The handling and behavior of the car, the consumption of gasoline and the actual speed of the car may change.
Tire Calculator - Size Comparison
Our Tire Calculator will show visual differences in tire diameter, profile, radius, clearance and width. Dashed lines show the difference in size. At the top, you can see a visual representation of the old tire (original size), and at the bottom, a visualization of the new tire. Just as you noticed, the tire can be seen in lateral and frontal projection. You can copy the URL of the page and show it to other people and they will see the same comparison as you see.
But how to understand all these values and the difference in %? To do this, we created a tire calculator, it will help you understand the change in all the necessary characteristics and show the difference in% between the old and new tires, and even visually display how the wheel of the old and new sizes will look like. You just need to enter the tire width, profile and wheel radius. Usually they are displayed in this form - 195 \ 65 R15 (photo 2).
How to use the online tire calculator?
Our online tire calculator is very easy to use. In the upper left corner of the site, there are fields for choosing a tire size. In the top row, you need to indicate the size of your original factory tire (or the tires that are currently installed on your car). These values are written on the tire profile (side surface). In the first list, you need to select the tire width - it is indicated in millimeters. The second list is the percentage of profile height to tire width. The third list is the disc diameter in inches (commonly referred to as the radius).
In the bottom row you need to enter the size of the new tyres. Tires that you are going to install on a car or have already bought. Then click "Calculate". Our tire calculator will calculate the differences between the old and new tires and display them in a table and a picture. Namely: diameter, width, circumference, tire profile height, number of revolutions per kilometer and change in car clearance. The first columns of the table will show the parameters for old and new tyres, the following columns will show the difference in mm and the percentage difference between them.
At the bottom of the tire calculator there is a speedometer to visually compare the speed of the old and new tires. Under the speedometer, you can speed up and slow down and see the change in speed difference between the old and new tires.
Be careful!
Drive carefully and follow the manufacturer's recommendations. The reverse side of installing non-standard tire sizes is the risk of losing insurance in case of an accident, not passing the state technical inspection of the car, since setting tires that are not approved by the factory is considered a change in the design of the vehicle.
The first and second columns specify standard tire and wheel sizes. In the remaining columns, the dimensions desired for installation. The calculator will help determine tolerances and selection alternatives.
Tire calculator allows you to compare the dimensions of tires of different sizes. For example, choose wider tires, but keep the outer diameter of the wheel the same or find out how much the car's ground clearance will change if you put tires of a different profile.
To select an alternative size in one half of the calculator, you need to specify the standard or existing tire size, in the next half - the desired or alternative.
The calculator displays the recommended rim width for a particular tire size, as well as the outside diameter and wheel width. The most important parameter is the outer diameter of the wheel. You should pay the most attention to its change.
The second important parameter is the actual height of the tire profile. It is usually expressed as a percentage of the width: for example, 205/55 R16, where 55 is 55% of the tire's width. That is, 205*55/100=112. 75 mm is the actual profile height of this tire.
Tires with different widths, standardly installed on a car, have different profile heights in percentages, but the same in millimeters. For example, tires with dimensions 275/40 R20 and 315/35 R20 have a profile height of 110 and 110.25 mm, respectively.
Some features of tire selection:
Wider tires give better handling, but less hydroplaning resistance and more rutting, and reduced comfort - low profile tires are stiffer.
Lower profile - heavier wheel. This is due to the fact that the disk is heavier than rubber, the mass of the wheel increases and this worsens the performance of the suspension. In addition, the mass of metal is distributed closer to the outer edge of the wheel and increases the moment of inertia (for cars with a powerful engine, this is not essential).
With an increase in the profile, the car becomes more rolly, less responsive to control, but it passes bumps more easily, tires are less sensitive to sharp edges of pits, comfort becomes better.
A significant change in the outer diameter of the wheel leads to a distortion of the readings of the vehicle's instruments, in particular, mileage and speed.

Correct selection of tires and wheels for the vehicle
As the wise proverb says, "Measure seven times and cut once." Therefore, when deciding to replace the tires and wheels on your car, first select the dimension that is suitable specifically for your car. And the tire selection calculator is best suited for these purposes - an online service for car owners, created just to simplify and speed up the selection of tires and wheels.
Since everyone who decides to abandon standard-sized wheels faces a similar task, and not everyone knows how to choose the right tire size, the tire disk calculator has taken a well-deserved place in the list of useful services for car owners on our website. Use the tire and rim size calculator to help you make the right choice.
Online tire and wheel calculator
The proposed tire and rim calculator has obvious advantages that its users have appreciated in practice, many among them believe that this is the best tire calculator on the Runet.
Clearness of calculations
The visual wheel and tire calculator contains a schematic image of a car wheel, which immediately displays the values specified in the calculator, which allows you to visually see the changes in the dimensions of the wheel when changing its parameters.
Auto tire calculator will quickly select possible sizes
Online tire calculator allows you to select tires by size for any passenger car in a few clicks. A quick and easy calculator for selecting tuning wheels for non-standard tire sizes. In a matter of minutes, you can determine the maximum or optimal dimensions of the disc radius, its offset, as well as the width and height of the tire profile.
You can choose tires for almost any car
First of all, the service was conceived as a calculator for selecting tires and rims for passenger cars, however, the ability to make calculations for wheels with a rim diameter of up to 20 inches allows, in suitable cases, to use this online program for those who need a truck tire calculator (tire calculator for truck tires).
Selection of rims by tire size and selection of tires by rim parameters
The online tire and rim selection program allows you to match rims to tires and determine the right tire size for your car.
Wheel tire calculator works online
Online Tire Calculator does not need to be downloaded and installed, the service is always available online. The convenience of the online service lies in the fact that it allows you to use the possibility of selecting tires and rims in real time and without registration. Access to the tire calculator is possible from any device with Internet access.
How to use the tire disc calculator
The visual tire calculator offers a comparison of tires of different sizes. Using the calculator is very easy. As you can see, the bus disk calculator is divided into two parts. The upper area of the calculator includes fields for selecting tire and wheel parameters, as well as a graphical representation of the wheel, where changes are displayed on the fly, once all dimensions are determined. And the lower area, which offers a complete table of sizes for wheels of different diameters with tires of various widths and profiles that could fit the dimensions you specified recommended by your car manufacturer. The presented dimensional table of possible tires and disks allows you to quickly obtain information about the dimensions suitable for the car.
The main problem that the tire-disk calculator solves is that it allows you to choose a “cheap” tire size. For those who are not in the know, there are expensive tire sizes and cheap ones, but cheap not because the tires are bad or a ten-year release date, but because the sizes are not popular with manufacturers, although changes from the size recommended by the manufacturer will be very small. Using the calculator, you can quickly determine the most inexpensive tire size for your car, after which it will be easier to decide on the manufacturer.
If with summer tires inexpensive options can come across in any dimension, since a pattern has not been identified, then with regard to winter tires everything is more or less obvious. If you add 5% of the profile height from the original size to the tire size recommended by the manufacturer of your car for search. Then for the same manufacturer of car tires, the difference in the sale price can be up to 30%. The calculation formula is simple, the higher the profile of the wheel (within reasonable limits), the cheaper it can cost.
Virtual tire calculator for rims and tires will help you make the right choice!
Service users do not need to make complex independent calculations of the difference in allowable tire sizes and wheel offsets, the disk-tire calculator provides a detailed comparison table between the recommended size and the desired size, based on which you can easily make your choice.
In addition to the visual tire calculator, our website contains other useful online services for car owners.
You may need such a calculator if you want to install their analogues, but of a different size, instead of standard tires or disks. With it, you can visually represent dimensional changes and only then interpret them for a specific car. At the same time, the calculator is not a tool for selecting tires and wheels, since it does not contain a database of manufacturers.
When changing wheels and tires, taking into account the geometric data obtained from the tire calculator , it will not be superfluous to make several measurements yourself. First, the distance from the suspension to the wheel surface on the inside, as well as from the shock cup to the tread surface. Secondly, from the wing, as well as steering rods to the tread surface. At the same time, the geometric parameters of the new wheel assembly should not greatly exceed the size of standard tires and rims. Otherwise, unstable behavior of the vehicle is possible.
A few basic rules to remember when changing tires and rims.
Summer tire tread has a standard depth of 0.8-1 cm;
When installing discs with a larger diameter than standard, it is necessary to reduce the amount of overhang - for each inch of height, 3 mm of overhang;
It is not uncommon for hub bores on rims that are non-original to have a larger diameter. Therefore, when installing them, you need to use special rings for fixing;
In the event that the hole on the disk is smaller than the hub mounts, it is strictly forbidden to drill them, as well as to grind the hub itself;
The correct selection of non-original discs using a calculator will save the driving characteristics of the car;
If you are unsure of the compatibility of tires or wheels with your vehicle, do not install or seek professional assistance.
Some car owners eventually decide to install wheels with a larger diameter than originally specified at the factory. On the one hand, the car is being transformed, but behind the aesthetic beauty there is a technical error in the speedometer readings, which many people either do not know about or simply do not take into account. This is of course the choice of everyone, but you must admit that an unpleasant situation can arise when you drive your car, adhere to the speed limit, and the traffic police inspector who stopped you claims that you were driving in excess. Whom to trust, the inspector or the speedometer? Let's figure it out...
Here the situation can be twofold. If the installed size of tires and rims corresponds to factory standards (approved by the manufacturer), then there should be no problems with the speedometer readings (if, of course, it is in good order). But if the dimensions differ from those recommended by the manufacturer, then the inspector may be right.
Ideally, after installing non-standard tires, or wheels, or both at the same time, the speedometer should be calibrated. By default, manufacturers calibrate speedometers to the sizes that are indicated on the car body in the doorway on the driver's side, but if the sizes are different, then the speedometer starts to show not entirely reliable data.
The other day I came across a very interesting little program. The speedometer error calculator when replacing tires and disks is an auxiliary tool for the correct replacement of disks and tires installed on a car. If you want to change tire sizes or put wheels of a different radius, this program will help you find out how external indicators will change, calculate the speedometer error, and show changes in the car's ground clearance (clearance).
185/60/R14 - factory tire values for civilian versions of the 6th generation sivok; 195/55/R15 - factory tire values for a generation.
Attention! Manufacturers and many car services do not recommend installing wide tires on a car during the winter season - this is due to the deterioration of the car's braking performance.
Another useful tool is a wheel width calculator, because when changing tire parameters, it is very important to check the compatibility of the width of the rim installed on the car. In the worst case, you simply will not be able to pull the rubber on the disk. This small calculator will help you calculate the minimum and maximum rim widths that fit the selected tire size.
Using these two calculators, you can easily determine the size of car tires or choose new rims for the required tire size.
Perhaps that's all I wanted to show and tell you for today.
Attention #2! The calculator for calculating the speedometer error and comparing tire sizes is provided for informational purposes only and does not guarantee 100% correct data. Contact a tire specialist for advice!
