In order to choose the right tires for the wheels, you need to know certain parameters, the non-observance of which will seriously worsen the car's behavior on the road. Since the tire is put on the rim of the disc, the width of the profile must be commensurate with it. Let us immediately note that, despite the widespread last years tuning, automakers categorically do not recommend it. After all, if the sizes of disks and tires vary greatly, then the contact patch will not be even, which means that the control can get out of control.
In general, the question of matching tires and wheels can be considered 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 a tire on a rim and the position of the wheels relative to the wheel arches, which includes negative camber, low landing and other frills, which we will not talk about, because we consider it more important to tell you how to choose the right tires for the rims from the point of view of safety and comfort.
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, PCD disc(diameter of the circle of the centers of the fixing holes) cannot be changed. In extreme cases, the sizes of wheels and tires may not match each other quite a bit, but then eccentric bolts are used for fastening, which allow you to install wheels 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 tires and rims should still match one hundred percent.
The dimensions of the rims and tires must also match with their central hole, but if for some reason this is not possible, an adjusting ring (it is also a spacer ring) will come to the rescue. The adjusting ring has an outer diameter equal to the diameter of the hole in the disk, and the inner diameter corresponds to the diameter of the vehicle hub. If the adjusting ring is set correctly, then driving performance not change. It should be noted that the discs do not have stamped mounting rings. Install them only on .
Disk labels do not indicate maximum load (MAX LOAD), you can find out this parameter either in the passport, which is attached by some manufacturers domestic wheels on your products, or look for this information on the disc manufacturer's website. This information is not very important, since manufacturers usually make discs with a margin of safety. But, if for some reason you decide to put, say, rims for a car on a jeep, then the maximum disk load will be important parameter. And if it is not taken 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 rims match in all respects, there is still a risk that the rim will not fit on the car. The reason for this is the so-called X-factor, when the disc rests on the suspension parts or caliper, which is associated with the shape of the stamping or casting. Therefore, we recommend that you first try it on before beading the tire on the wheel.

Instruction
Look at the nameplate in the doorway on the driver's side for the recommended tire size. Write it down on paper or memorize it. Find wheels with this size in the car shop and use a tape measure to measure the outer diameter of the tire. Write this value down on paper. Drive the car into the pit and turn the front wheels completely: first in one direction and then in the other direction. Measure the distance from the tire to the nearest structural element with a ruler or tape measure and write these values down on paper.
When choosing the tires you like, consider the diameter of future rims, and, depending on the size of the future tire, select 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 14-inch rims instead of 13 and fit 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 dimensions which will be approximately the same as recommended. 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 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 tire width may differ from the tread width, so if you want a wider tread, then pay attention to this feature. Do not take tires with low load and speed ratios.
If you want to put R16 wheels on your car instead of R13, find the right tire width. Since 175mm wide R16 tires don't exist, it's more realistic to find 215mm or wider tires. Look at your notes and calculate how many centimeters you have left. Increasing the tire width by 1cm more than recommended reduces the measured distance between the wheel and the body by 5mm. Please note that it is not advisable to increase the diameter of the wheel by more than 3 cm, as this will lead to increased consumption fuel and deterioration traction characteristics cars. Select suitable tires and measure their diameter with a tape measure. Compare with recommended wheel diameter. If the recommended dimensions of the future wheel are exceeded within your calculated norm, you can safely buy the selected tires. The speed and load coefficient in this case will significantly exceed the recommended one, which will have a beneficial effect on the durability of rubber.
Buying a new question tires for a car sometimes baffles novice motorists. Selection criteria tires for a car a lot: winter or summer tires, tread pattern, manufacturer, and most importantly - size tires which is necessary for your specific car.
You will need
- - technical documentation of the car;
- - "tire" calculator.
Instruction
Examine the vehicle's documentation. Find manufacturer's recommendations by type and size at tires, which can be used on this vehicle. IN general case options tires you will be indicated, for example, in the following form: 175/70 R13, where 175 is the profile width tires s, mm, and 70 - profile height tires s in relation to the width,%; R13 - radius tires s in inches. If the profile height is not specified, then it is assumed to be 82%. Radius tires s determines the diameter of the wheel on which this tires y.
If for some reason you do not have documentation for the car, look for information on the car itself. As a rule, a sticker with basic information about the car is located on driver's door. The label usually indicates size tires and allowable pressure in them.
Find information about size e one of tires of your car on its sidewall.
If the information from the nameplate sticker has been erased and there is no way to find this information in one of the following ways, use the " tires calculator" on one of the automotive sites. Select the make, model, year of manufacture and modification of the car and find out size s tires s for the entered parameters.
note
Prolonged use of tires that are not the correct size for your vehicle can damage your vehicle's fender liner and cause suspension parts to fail quickly.
Before buying a set of new tires, study the marking procedure for car tires. On a new tire, with any marking (European, American or Japanese), its main characteristics will be marked with an alphanumeric code. Knowing these markings will help you choose the right tire and possibly avoid later emergency.

Going to the store for clothes, the buyer is often faced with the fact that he cannot immediately determine his size. This is due to the fact that each country has its own designation systems. size and it's not easy to figure it out.
Instruction
You can also contact a car service, where an experienced specialist will determine diameter wheels with specialized tools. All calculations in this case will be immediately made in inches, which will facilitate your task.

Correctly selected car tires provide security and implementation specifications car. If it is not possible to install tires recommended by the automaker, it is necessary to select an interchangeable tire size, taking into account several parameters.
Look at the combination of letters/numbers on the tire. Most tire sizes begin with a letter or letters that identify the type of vehicle and/or use for which they are designed. General indicators:
- P225/50R16 91S
- P: When the tire size starts with "P", it means that the tire size is specified in the "P-metric" system, which is designed to be used primarily in passenger cars. This includes cars, minivans, "parquet" SUVs and light pickups (usually with a carrying capacity of 250–500 kg). Dimensions in the P-metric system began to be used in the late 1970s, today they are most often used.
- /50R16 92S: If there is no letter followed by three numbers first, then it is a tire with metric size(also called "Euro-metric" because these measurements originated in Europe). In addition to the fact that the Euro-metric system is used on European cars, it is also used on vans and "parquet" SUVs. Euro-metric dimensions are equivalent to P-metric dimensions, but generally differ slightly in maximum load capacity.
- T125/90D16 98M
- T: If the tire size starts with "T", it means that the tire is "spare" (temporary spare) and can be used until the flat main tire is replaced or repaired.
- LT245/75R16 108/104S
- LT: If the tire size starts with "LT", this means that the tire size is indicated in the "Light Truck-metric" system designed for use on vehicles capable of hauling heavy loads or towing large trailers. This includes medium and heavy (750-1000 kg capacity) pickup trucks, parquet SUVs and full-size vans. Tires with the designation "LT" are the "little brothers" of tires that are used on an 18-wheel tractor and are designed with a significant reserve load to withstand the additional load of transporting heavy loads.
- 50R16LT 112/107Q, 8.75R16.5LT 104/100Q or 31x10.50R15LT 109Q
- LT: If the tire size ends with "LT", it means that the tire belongs to the early marking systems - "Numeric" (numeric), "Wide Base" (wide base) or "Flotation" (flotation), designed for use on vehicles capable of carrying heavy loads, as well as on trailers (numeric marking system). The rim diameter of these tires starts at 16.5" (wide base), tires big size allow the vehicle to overcome mud and sand (flotation) surfaces. This includes light, medium, and heavy (typically 500 kg, 750 kg, and 1,000 kg payloads) pickup trucks and "parquet" SUVs. Tires with "LT" at the end are also " younger brothers» tires that are used on an 18-wheel tractor and are designed with a large reserve load to withstand the additional load of transporting heavy loads.
- /70R15C 104/102R
- C: If a tire with a Euro-metric size ends in "C", it means that the tire is a commercial tire and should be used on vans or distribution vehicles that are capable of transporting big loads. In addition to being marked with the letter "C" in the tire size, they are also marked with the appropriate service description and "load range" (load range B, load range C or load range D).
- ST225/75R15
- ST: If the tire size starts with "ST", it means that it is a "Special Trailer Service" tire and is intended for use on caravans general purpose and for transporting boats or cars. These tires cannot be used on cars, vans or pickup trucks.
Look at the three digit number. It indicates the width of the tire profile in millimeters.
- P225/50R16 91S. 225 indicates that the width of the tire is 225 millimeters from the widest part outside to the widest side of the inside when installed and measured on a wheel of a certain size.
Look at the two numbers after the tire section width. This is the tire height ratio.
- P225/50R16 91S. 50 means that the height of the tire (from the seat rim to the outer edge of the wheel) is 50% of the profile width. This value is the height of the tire profile, and is also called its series, profile and the ratio of the height of the tire profile to its width. The larger this value, the larger the sidewall of the tire, and vice versa. We know that the width of the tire profile is 225mm and the height is 50% of 225mm. Accordingly, multiplying 225 by 50% (0.50), we get a profile height of 112.5 mm. If the tire size is P225/70R16, then by multiplying 225 by 70% (0.70), we get a profile height of 157.5, which is 45 mm more.
Look at the letter that follows the numbers - it stands for the radial design of the tire.
- P225/50R16, P225/50ZR16. The R in P225/50R16 91S indicates that the tire is of radial construction and the cords in the carcass plies are arranged radially. Today it is the most popular type of tires. 98% of all tires sold are radial.
- If the tire size instead of R is D (225 / 50D16), this means that the tire has a diagonal carcass type, and its design consists of intersecting cord layers. Tires with this design are intended for use as spares and for light duty trucks.
- If instead of R there is B (225/50B16), then the tire has not only diagonal frame, as before, but also reinforced with belts in the tread area. This type of tire construction is called "Belted". Today, tires with this design are almost gone.
Look at the speed index. To date, the only type of tire that has a speed index included in its size is "Z-speed rated" tires. In this case, after the two digits used to identify the ratio of the height of the tire profile to its width are the letters ZR, which determine the speed index (Z) and internal structure tires (R). Since 1991, all other types of speed index markings are listed in the service description (which you will learn about shortly).
Consider the diameter of the tire and wheel.
- P225/50R16 91S. 16 indicates that the tire is suitable for a 16" rim.
- Tires rated in inches (P225/50R16, as well as 8, 10, 12, 13, 14, 15, 17, 18, 19, 20, 22, 23, 24, 26 and 28) are by far the most common and on most cars, minivans, vans, "parquet" SUVs and light trucks small load capacity. Although not as common, two additional "unique" types of tire/wheel diameters are still in use today.
- Tires and rims with a diameter of 0.5" pitch (8.00R16.5LT, as well as 14.5, 15.5, 17.5, 19.5) are used on some heavy trucks, light trucks heavy duty and covered wagons.
- If the diameter of tires and rims is expressed in millimeters (190 / 65R390, as well as 365, 415), this system is called millimetric. Michelin used a millimetric system for their TRX tires, which were used in limited numbers on different cars in the late 1970s and 1980s.
- The Michelin PAX system is an integrated runflat tire/wheel system; she was presented in North America as original equipment. For example, the dimensions of the tire and rim of the PAX system are indicated in millimeters - 235 / 710R460A 104T (235 mm - tire profile width, outside diameter tires - 710 mm and 460A mm - rim diameter), the letter "A" in 460A indicates that tires with asymmetric beads, the outer (450 mm) and inner (470 mm) beads have different diameters.
- All of these "unique" tire/wheel diameters were designed specifically for a tire/wheel project, or a particular vehicle required tires or wheels of a specific size. The bead profiles of all these tires and wheels are shaped differently from the traditional "inch rims".
Rubber profile: what is it, what is the minimum and maximum height? Find answers to all questions about the size of tires for a car in this article.
When choosing tires, novice car owners often ask the question “tire profile height: what is it?” To find out the profile of the rubber, just look at the markings on its side. The main thing is to be able to correctly decipher the meaning of these numbers.
Rubber profile: what does it mean and how to recognize it?
On the sides of the tires there is information about all of them. design features and properties. The first digits of the marking indicate its width in millimeters, the next - the height, which is expressed as a percentage of the height. Next is the type of rubber and the landing size, which is expressed in inches. If the height of the tire is 55% or less of its width, it is considered low profile.
Tires marked 225/40/R18 have a seat size of 18 inches and a width of 225 millimeters. The last indicator shows the distance between the outer surfaces of the side walls of the rubber, inflated to standard pressure.
Important: when determining the width, elevations due to additional belts, letters, contours and tire upholstery are not taken into account. It is advisable to buy wheels of the width specified by the manufacturer. In general, this parameter should not exceed the width of the wheel rim by more than 30%.
The R index refers to the radial design of the tires. However, diagonal tires are almost out of production. The height of the rubber profile with this marking is 112.5 millimeters (50% of 225 mm). Like the tread height, the size of the tire profile greatly affects the car's handling and driving comfort on poor quality roads. Now that we have figured out what tire profile height means, it's time to find out what it can affect.
What affects the height of the tire profile
What does tire profile height mean? This parameter allows you to determine the outer diameter of the wheel. So if landing diameter is 15 inches (381 millimeters) and the tire profile is 50% of 170 millimeters (170/2=65 mm), then the total wheel diameter with the tire inflated will be 381+65*2=315 millimeters.
What is the profile of a tire? Manufacturers do not recommend installing tires with a size different from that specified in the operating instructions. However, small changes are quite acceptable, although they change performance characteristics cars. This parameter depends on:
- controllability of the car and reaction time to turn the steering wheel;
- comfort when driving through pits and other irregularities;
- the required tire pressure;
- fuel consumption;
- throttle response and maximum speed;
- the accuracy of the speedometer readings;
- braking distances;
- chances of disk damage due to hitting the pit.
By installing tires of different heights, you can adjust these parameters within reasonable limits.
What is the height of the tire profile measured in
When marking, the height of the tire is indicated as a percentage of the width, but it is more convenient to know what the height of the tire profile is in centimeters. Calculating the height of the rubber is simple - elementary knowledge in mathematics is enough. You need the width value, which is indicated in millimeters, multiplied by the percentage indicated in the marking and by 10. So, if the width is 175 and the profile is 60%, then the height of the rubber in centimeters is 10.5 centimeters (175 * 60% * 10 = 10 ,5).
As you can see, if a marking is indicated on the side of the tire, the calculation of the profile will not be difficult. What to do if you need to find out the rubber profile in centimeters, and the marking is erased or missing for some reason?
How to find out the height of the tire profile
To find out this indicator, it is necessary to measure the difference between the outer and inner diameter of the tire (the actual height of the profile in centimeters) and divide it by the distance between the outer edges of the rubber. The resulting value shows the ratio, which is indicated on the side of the wheel.
Now you know how to determine the height of a tire profile.
Everyone has heard expressions like “low profile tires” or “high profile tires”. How to calculate the profile height of a tire and find out if it belongs to the "high" or "low" models?
Low profile rubber
Those who are poorly versed in the problem of choosing tires often ask: "How many millimeters is a low profile rubber?"
It is impossible to answer such a question, since it is formulated incorrectly. The low profile of rubber is not defined in absolute terms (centimeters or millimeters), but in relative terms.
The automotive industry is constantly evolving, and as a result, many standards are changing. If in the 1970s a profile of less than 80% was considered low, today even 60% does not belong to such. Even with a height of 55% of the width, the profile is far from always considered low. Size 205/55 R16 has become the most popular among modern cars middle class. Such rubber often does not have a special rib to protect the disc from impacts. Therefore, manufacturers do not classify it as a low-profile. Although with a width of 185 millimeters, a profile of 55% (92.5 mm) is already quite low
It is safe to say that low profile tires are anything less than 50-55% and are equipped with a rib to prevent damage to the rim.
According to European standards, the lowest rubber profile is 20. These are 375/20 R21 tires. However, Nexen and Kumho have recently introduced the lowest tire profiles: 375/15 24" and 385/15 22".
We can say that low profile tires are now limited to 15%.
High profile rubber: pros and cons
This type of tire includes those that have a height marking of 80: and more. They are commonly used on SUVs, pickups and trucks. A high profile tire, like a low one, has its advantages and disadvantages.
The advantage of such rubber is that it is ideally suited for driving on potholes, pits and off-road. High rubber easily absorbs shock, providing less stress on the suspension and protecting the disc from impacts. However, when driving on high-quality asphalt or concrete pavement, they do not behave in the best way. The higher the tires, the more they deform under side load. As a result, the car reacts with a delay to the steering wheel and “holds the road” poorly when driving along the highway for high speed.
Another feature of high-profile tires, because of which they are not put on small cars, is the reduction in disk size. In the same wheel arches either large wheels with low profile tires, or small ones with high profile tires can fit. In the latter case, constructors have to reduce the size brake drums and discs, which impairs braking performance.
Which tire profile height is better
First of all, the height of the tires must comply with the manufacturer's recommendations. If it is too high, the wheels simply will not enter the arches and will catch them on turns or bumps. Installation low profile tires without installing discs with a large outer diameter, it will reduce the clearance of the car, which will make it difficult to move on the dirt road and the fret, passing through the speed bumps.
One can only say which profile is better for specific driving conditions.
If you have to travel broken roads, dirt and off-road, high profile will behave excellently. You can hardly worry about the edge of the pit being bent or broken. rim, and the car will “sit on the bottom” due to too low ground clearance.
But if you try to perform a "snake", you can see how the car "walks", reluctantly responding to the steering wheel. Also, such rubber begins to “float” along the road at high speed, deviating from a given trajectory. Therefore, it is impossible to say unambiguously which profile is better.
Low-profile tires provide excellent handling, but can cause disc failure or deformation. Therefore, the driver himself should decide which profile is better, based on operating conditions. The only thing to keep in mind is the installation on regular disks a lower tire leads to an overestimation of the speedometer and odometer readings, and a higher one leads to an overestimation. In the latter case, you can earn a ticket for speeding if you do not first check the accuracy of the speedometer.
It is because of the overestimation of the odometer readings that drivers who installed low profile tires note the reduction in fuel consumption.
Tires of different heights on a car
The difference in the height of the tire profile affects its grip performance with pavement and behavior when passing rough sections of the road. Is it possible to put tires of different heights on the wheels of a car?
From the point of view of traffic rules (clause 5.5), the answer is this: you can put only the same rubber on one axle. The difference in the profile of rubber on the same axle is unacceptable. This is punishable by a fine or a warning. The only option when tires with different profile heights can be on the same axle - driving on a “spare tire” to the nearest tire fitting workshop. In this case, even a “stowaway” can be on the car. However, it must be remembered that it can only be placed on rear axle: it does not have steering wheels and the load on it is less. If you have broken front wheel, you should replace it with a whole rear one, and put the “dokatka” back.
Different heights of tires on the axles are not prohibited when it comes to the difference between the front and rear wheels. If you put a higher tire forward and a lower one back, or vice versa, there will be no complaints from the traffic police inspector. The main thing is that seasonality coincides or that studded tires are not on one axle, while on the other - without studs.
But answering the question of whether it is possible to put rubber of different heights, you need to understand that different height And different behavior rubber can cause skidding. Therefore, it is better not to experiment.
What is a tire calculator for?
With this tire calculator you can easily calculate how to change: outer dimensions of the wheel, height ground clearance(clearance), speedometer readings and other characteristics when tires with a different size are installed on your car.

The site of the online store contains a convenient tire calculator that makes it easy to calculate changes in wheel parameters when switching to another tire size. With this online tool, you can calculate external wheel measurements, ground clearance (ride height), calculate speedometer readings and other characteristics.
With the onset of the new season, every responsible car owner considers it necessary to change tires in accordance with the season. The best option will install tires of the size recommended by the automaker for a particular brand of car. In cases where this is not possible, deviations in diameter in the 2% range are allowed.
Replacing tires requires a serious approach. When choosing new tires and wheels, it is necessary to take into account such indicators as:
- tire width,
- profile height,
- wheel inner diameter,
- valid speed indices.
Incorrectly selected tires can cause malfunctions in the car's electronics, increase fuel consumption, worsen driving comfort, and also cause problems during a vehicle inspection at the traffic police.
How to calculate tires?
To select the tires of the required size, you need to use the tire calculator, which determines the theoretical dimensions. All measurements are in millimeters and speed is in km/h. To make a calculation, you should enter the parameters of the tires of your car in the appropriate line. Then enter dimensions new tire and the disk to be installed. After specifying all the parameters in the table below, information will appear on changes in the tire width and profile height, inner and outer diameters, and the difference in speeds (real and according to the speedometer).
What to look for when choosing a tire
- Installing tires and rims custom size can lead to damage to the tire itself, damage to the disc and reduce the performance of the car. When choosing tires, it is better to rely on the recommendations of the automaker.
- If the diameter of the wheel disc is larger, then in this case the load on the suspension may increase. To maintain the same diameter of the outer wheel, the height of the profile should be reduced.
- If you choose tires with a greatly increased profile, you need to be prepared for a loss in the quality of car handling. The tire can rub against the body and suspension, causing rapid wear.
- Even with the slightest difference between the indicators on the speedometer and in reality, the error can increase many times with an increase in speed, which makes driving unsafe.
- narrow or too wide rims can cause tire deformation. This, in turn, will lead to premature wear and poor performance.
