Correct selection of tires and wheels for the car
As the wise proverb says, "measure seven times and cut once." Therefore, having decided to replace the tires and wheels on your car, first select the dimension that is suitable specifically for your car. And the best for these purposes is a tire selection calculator - an online service for car owners, created just to simplify and speed up the selection of tires and wheels.
Since everyone who has decided to abandon standard-size wheels faces a similar task, and not everyone knows how to choose the right tire size, the tire disk calculator has taken its 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 offered tire and wheel calculator has obvious advantages, which in practice have been appreciated by its users, many of them believe that this is the best tire calculator on the Russian Internet.
Visibility of calculations
The visual tire and wheel calculator contains a schematic image of a car wheel, which immediately displays the values indicated in the calculator, which allows you to visually see changes in the dimensions of a wheel when changing its parameters.
Car tire calculator will quickly select possible sizes
The online tire calculator allows you to select tires by size for any passenger car in a few clicks. Fast and convenient calculator for the selection of 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 find tires for almost any car
First of all, the service is conceived as a calculator for the selection of tires and wheels for passenger cars, however, the ability to make calculations for wheels with a rim diameter of up to 20 inches allows, in appropriate cases, this online program can be used for those who need a truck tire calculator (tire calculator for trucks). tires).
Selection of disks by tire size and selection of tires by wheel parameters
The online tire and wheel selection program allows you to select both wheels and tires, and determine the appropriate tire size for your car.
Wheel tire calculator works online
The 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 possibilities of selecting tires and rims in real time and without registration. The bus calculator can be accessed from any device with Internet access.
How to use a tire disk calculator
The Visual Tire Calculator offers a comparison of different tire sizes. The calculator is very easy to use. As you can see, the shino disk calculator is divided into two parts. The upper area of the calculator includes fields for selecting tire and rim parameters, as well as a graphical representation of the wheel, where changes are displayed on the fly as soon as all dimensions are determined. And the lower area, which offers a full table of sizes for different rim diameters with tires of different widths and profiles, which would fit your specified dimension as recommended by your car manufacturer. The presented size table of possible tires and rims allows you to quickly obtain information on the dimensions suitable for the car.
The main problem that the tire-disk calculator solves is that it allows you to choose the "cheap" tire size. For those who are not in the know, there are expensive tire sizes and cheap, but cheap, not because the tires are bad or a ten-year production date, but because the sizes are not popular with manufacturers, although the changes from the manufacturer's recommended size will be very minor. Using the readings of the calculator, you can quickly determine the most inexpensive tire size for your car, after which it will be easier to determine the manufacturer.
If with summer tires inexpensive options can be found in any dimension, since the 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 dimension recommended by the manufacturer of your car. Then the same manufacturer of car tires, the difference in the selling 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.
A virtual tire calculator for rims and tires will help you make the right choice!
The users of the service do not need to make complex independent calculations of the difference in the permissible tire sizes and displacement disks, the disco-tire calculator provides a detailed comparison table between the indicators of the recommended size and the desired one, being guided by which you can easily make your choice.
In addition to the visual tire calculator, our website contains other online services useful for car owners.
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 you install tires with a different standard size 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 body parts and suspension of the car, which will subsequently lead to its destruction.
Do you want to choose a tire for your car, but don't know much about tire labeling? It's not a problem! In this section, we will help you figure out: what are the parameters of the tire, what they mean, and what kind of tire is suitable for your car.
Find tires / tire catalogDecoding of tire marking.
195/65 R15 91 T XL
195 is the width of the tire in mm.
65 - Proportionality, i.e. the ratio of the height of the profile to the width. In our case, it is equal to 65%. Simply put, with the same width, the larger this indicator, the higher the tire will be and vice versa. Usually this value is referred to simply as “profile”.
Since the tire profile is a relative value, it is important to take into account when choosing rubber that if instead of the 195/65 R15 standard size you want to put tires with the size 205/65 R15, then not only the width of the tire will increase, but also the height! Which is unacceptable in most cases! (except for cases when both of these standard sizes are indicated in the car manual). You can calculate the exact data on the change in the outer dimensions of the wheel in a special tire calculator.
If this ratio is not indicated (for example, 185 / R14C), then it is equal to 80-82% and the tire is called full profile. Reinforced tires with such markings are usually used on vans and light trucks, where a high maximum wheel load is very important.
R- means a tire with a radial cord (in fact, now almost all tires are made this way).
Many people mistakenly think that R- stands for the radius of the tire, but this is precisely the radial design of the tire. There is also a diagonal design (denoted by the letter D), but recently it has practically not been produced, since its performance is much worse.
15 - wheel (disk) diameter in inches. (It is the diameter, not the radius! This is also a common mistake). This is the "landing" diameter of the tire on the disc, i.e. it is the inner size of the tire or the outer at the rim.
91 - load index. This is the maximum permissible load per wheel. For cars, it is usually done with a margin and when choosing tires is not a decisive value, (in our case, IN - 91 - 670 kg.). For vans and small trucks, this parameter is very important and must be observed.
Tire Load Index Table:
T- tire speed index. The larger it is, the faster you can ride on this tire (in our case, IS - N - up to 210 km / h). Speaking about the tire speed index, I would like to note that with this parameter the tire manufacturer guarantees the normal operation of the rubber with the constant movement of the car at the specified speed for several hours.
Speed Index Table:
American tire markings:
There are two different markings for American tires. The first one is very similar to the European one, only the letters "P" (Passanger - for a passenger car) or "LT" (Light Truck - light truck) are put in front of the standard size. For example: P 195/60 R 14 or LT 235/75 R15. And another marking of the tire, which is fundamentally different from the European one.
For example: 31x10.5 R15(corresponds to European standard size 265/75 R15)
31
is the outer diameter of the tire in inches.
10.5
- tire width in inches.
R- a tire of radial design (older models of tires were with a bias design).
15
is the inner diameter of the tire in inches.
Generally speaking, apart from the unusual inches, the American tire marking is logical and more understandable, unlike the European one, where the tire profile height is not constant and depends on the tire width. And here everything is simple with the decoding: the first digit of the standard size is the outer diameter, the second is the width, the third is the inner diameter.
Additional information indicated in the marking on the sidewall of the tire:
XL or Extra Load- a reinforced tire, the load index of which is 3 units higher than that of conventional tires of the same standard size. In other words, if a load index of 91 is indicated on a given tire, marked XL or Extra Load, then this means that with this index, the tire is able to withstand a maximum load of 670 kg instead of 615 kg (see the table of tire load indices).
M + S or M&S tire marking (Mud + Snow) - mud plus snow and means that the tires are all-season or winter. Many summer SUV tires are labeled M&S. However, these tires must not be used in winter because winter tires have a completely different rubber composition and tread pattern, and the M&S badge indicates a good cross-country performance of the tire.
All Season or AS all-season tires. Aw (Any Weather) - Any weather.
Pictogram * (snowflake)- rubber is designed for use in harsh winter conditions. If the sidewall of the tire does not have this mark, then this tire is intended for use in summer conditions only.
Aquatred, Aquacontact, Rain, Water, Aqua or pictogram (umbrella)- special rain tires.
Outside and Inside; asymmetrical tires, i.e. it is important not to confuse which side is external and which is internal. When installed, the Outside lettering should be on the outside of the car, and Inside on the inside.
RSC(RunFlat System Component) - RunFlat tires are tires on which you can continue driving a car at a speed of no more than 80 km / h with a FULL pressure drop in the tire (in case of a puncture or cut). On these tires, depending on the manufacturer's recommendations, you can drive from 50 to 150 km. Different tire manufacturers use different designations for RSC technology. For example: Bridgestone RFT, Continental SSR, Goodyear RunOnFlat, Nokian Run Flat, Michelin ZP, etc.
Rotation or an arrow on the sidewall of the tire indicates a directional tire. When installing the tire, the direction of rotation of the wheel indicated by the arrow must be strictly observed.
Tubeless is a tubeless tire. In the absence of this inscription, the tire can only be used with a camera. Tube Type - means that this tire must be used only with a tube.
Max Pressure; maximum allowable tire pressure. Max Load - the maximum permissible load on each wheel of the vehicle, in kg.
Reinforced or the letters RF in the standard size (for example 195/70 R15RF) mean that this is a reinforced bus (6 layers). The letter C at the end of the dimension (eg 195/70 R15C) denotes a truck tire (8 layers).
Radial This marking on a rubber in a standard size means that it is a tire of a radial design. Steel means there is a metal cord in the tire construction.
Letter E(in a circle) - the tire complies with the European ECE (Economic Commission for Europe) requirements. DOT (Department of Transportation - US Department of Transportation) - American quality standard.
Temperature A, B or C heat resistance of tires at high speeds on a test bench (A is the best indicator).
Traction A, B or C- the ability of the tire to brake on a wet road surface.
Treadwear; the relative expected mileage compared to the US specific standard test.
TWI (Tread Wear Indiration)- indicators of tire tread wear indicators. The TWI wheel can also be marked with an arrow. The gauges are evenly spaced at eight or six places around the tire circumference and indicate the minimum tread depth allowed. The wear indicator is designed as a protrusion with a height of 1.6 mm (the minimum tread size for light vehicles) and is located in the groove of the tread (usually in the drainage grooves).
DOT- Coded manufacturer address, tire size code, certificate, production date (week / year).

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 around 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 in terms of 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, it is difficult to overestimate the usefulness of a tire calculator by car brand. 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.
In order to choose the right tires for the disks, you need to know certain parameters, failure to adhere to which will seriously worsen the car's behavior on the road. Since the tire is put on the rim of the rim, the width of the profile must be commensurate with it. We note right away that, despite the tuning widespread in recent years, automakers categorically do not recommend it. After all, if the sizes of disks and tires are very different, then the contact patch will not be even, which means that the control may get out of control.
In general, the question of matching tires and disks can be viewed from two sides. The first is the selection of tires and wheels based on the manufacturer's recommendations, and the second is this fitment. Fitment is the study of the fit of the tire on the rim and the position of the wheels relative to the wheel arches, which includes negative camber, low landing and other delights that we will not talk about, since we consider it more important to tell how to choose the right one in terms of safety and comfort tires to disks.
In order to choose the right tires for the rims, you need to know the labeling of the rims.
Ideally, that is, to be sure of safety, the PCD of the disc (the diameter of the circle of the centers of the mounting holes) should not be changed. In an extreme case, the dimensions of the rims and tires may not correspond at all to each other, but then eccentric bolts are used for fastening, which allow you to install rims with PCD 100 mm on cars with PCD 98 mm. However, it is worth noting that the maximum difference in displacement should not exceed 2 mm, and ideally, the alignment of tires and disks should be one hundred percent.
The dimensions of the rims and tires must also match with their central hole, but if for certain reasons this is not possible, an adjusting ring will come to the rescue (it is also a spacer ring). The setting ring has an outer diameter equal to the diameter of the hole in the disc, and the inner diameter corresponds to the diameter of the car hub. If the setting ring is put correctly, then the running characteristics will not change. It should be noted that the discs do not have stamped locating rings. Install them only on.
The disc markings do not indicate the maximum load ( MAX LOAD), you can find out this parameter either in the passport that some manufacturers of domestic wheels attach to their products, or look for this information on the website of the wheel manufacturer. This information is not very important, as manufacturers usually make discs with a margin of safety. But, if for some reason you decide to put, say, disks for a car on a jeep, then the maximum disk load will be an important parameter. And if you do not take it into account, the wheel may not withstand the load and deform, even falling into a small hole.
In addition, even if the dimensions of the tires and wheels are the same in all respects, there is still a risk that the wheel will not fit on the car. The reason for this is the so-called X-factor, when the disc rests against the suspension parts or the caliper, which is associated with the form of stamping or casting. Therefore, we recommend that you first try it on before mounting a tire on a wheel.
