Most popular tire models: Continental, Nokian, Michelin, Dunlop, Bridgestone, Kumho, Pirelli, Maxxis, Toyo, Nordman, Viatti and others.
2. Maximum load designation. Some firms write the small Max Load font (maximum load) and then indicate the load in kilograms and English pounds (the example of max load 515kg (1135lbs), 1LBS \u003d 0.4536 kg). I consider it necessary to warn from one misconception. Some drivers are considered sufficient to multiply this value by 4 (i.e., on the number of wheels) to obtain a maximum mass of the car tires with this load. So you can not do.
First, the resulting mass is strongly overestimated. Tires should not work under the maximum weight load. Therefore, from the maximum mass you need to take 20% - if you have passenger car or 30% - if an SUV. Secondly, if you take the right interest, it is not a fact that this mass will be permissible. Max Load is a limiting load, without binding to the design features of a particular car. And such a binding is obligatory.
3-4-5 - marker required according to regulatory documents about informing consumers (quality level); Tread Wear Index - Wire Resistance Index, Traction Index - Coupling Quality Index; Temperature index is a temperature index.
Treadwear - wear indicator. It has a value from 60 to 620 units with an interval 20. Reference tires have a value of 100. The more this indicator, the longer the tires will go. Wear resistance is determined by a special technique. Take two cars with reference tires and subjects. They pass a certain route longer than 10,000 km each other. Conditions for cars identical. According to the results, the intensity of wear is calculated, and how much this tires will pass to maximum run. For example, Nordman tires have Treadwear 500 units, and Continental is only 280.
6. The maximum allowable air pressure - indicated in kilopascals and "atmospheres" for the tire in a "cold" state (for example 3.0 atmosphere or 44psi). If specified maximum pressure 2.4 atm., then pump up above - dangerous.
The letter R means the radial "RADIAL" tire design and the mounting diameter of the rim. The diameter of the rim is measured in inches and millimeters. When translated, it should be considered 1 inch \u003d 25.4 mm. For example, we consider the label type R14 - this means not the 14th radius, but the radial design of rubber and its diameter of 14 inches.
11. Load index - Limit weight load that tire is withstanding. The affiliated two-digit number mathematically is not attached to a specific kilograms - this is a conditional index.

12. Speed \u200b\u200bcategory - Shows the maximum estimated tire speed. The table below indicates the equivalent maximum speed in km / h.
Table 2. Speed \u200b\u200bdesignation on tires (in the letters of the Latin alphabet).

The high-speed category assigned to the tire on the results of special tests implies the maximum speed. That is, the speed, with the slightest excess of which no one can ensure that the rubber will not start collapse. For operation, the "gentle" mode is installed - the car must ride at a speed of 10-15% less than the one that "admits" tires.
13. Design information - fixed on board by appropriate inscriptions on the number of layers of the breaker and frame, as well as the material of Cord. For example, the inscriptions of Tread Plies: 2 Polyester Cord + 2 Steel Cord + 1 Nylon Cord mean that the tire breaker consists of 2 layers of polyester + 2 layers of metal cord + 1 layer of nylon cord.
14. Additional information.
Twi is a pointer to the location of the wear indicator. The tread wear indicator itself must be sought on the bottom of the tread groove closest to the label (if there is an arrow, it specifies this particular groove). It shows the maximum allowable degree of "baldness" of the tire.
The date of manufacture - is shown in four digits in oval on the sidewall, and the first two denotes the week of manufacture, the rest is the year of manufacture. For example, the marking 4615 explains that they are released on the 4th anniversary, i.e. In November 2015.
Tubeless - Indicates that the tire should be used without a camera. The tubeless tire is different from the chamber that does not require an inflatable camera. Tube Type - designation for chamber tires.
PR is the problem of the layering. For passenger cars Using tires with 4PR layering norm and sometimes 6Pr, and in this case the latter have an inscription REINFORCED (reinforced). Tires with marking 6PR and 8PR are suitable for light trucks and minibuses, therefore, after the landing diameter designation (for example, 185R14C), they are set to "C" (Commercial).
How else are there notation? For example, the abbreviation "Front Wheel" or "Rear Wheel" occurs. The first indicates that the tire is installed only on the front axis of the machine, the second is only on the back. Also often encounters "Rotation" with a circular arrow - shows which side you need to install the wheel (the arrow shows how the wheel should rotate when the car moves forward). Such a pictogram is only for asymmetric rubber (drawing different along the edges), symmetrical can be installed by any side.
Always a responsible moment in the life of every motorist. But for independent choice Right automotive tires It is necessary to know the features of the design and understand the main marks that are applied to each car tire.
For everyone automotive tiresaH adopted the following combinations of the designation of the main parameters:
P 185/65 R14 86

Each tire has a number of parameters to which it is worth paying attention to when buying. All indicators are of great importance, because of them you can learn about the age of rubber, its characteristics. It will help you choose the shoes as possible for your car, based on the features of operation.
This article is devoted to the loading index of passenger cars. We will consider deciphering the parameters, which means these numbers where they are applied and how to choose a tire for your car.
All tire manufacturers need to be specified on their products a number of parameters. This includes the dimension of the wheel itself. Depending on the type of marking, these indicators may be marked in millimeters or inches.
Look at the sidewall rubber. If there are parameters, for example, 225 * 55 * R17, then this suggests that the kit is manufactured for consumers from European countries. Tire manufacturers for Europe apply a certain number of numbers that talk about the following sizes:
- the first number indicates the distance from one side part to the other, i.e. tread width - 225 mm;
- the second is the ratio of the tire profile to the width or height of the tread. It is important here to understand that this indicator is variable and depends on the width of the tire. That is, the auto strokes 225 * 55 * R17 and 185 * 55 * R17 differ in their sizes;
- the third is deciphered as the inner diameter - 17 of inches;
- the letter R says that we have a tire with a radial weaving cord. There are still diagonal tires, where the "\\" icon is affixed instead.
American companies have developed their own labeling of their products, where the tire size is indicated in inches. The overseas type of designation has a format, for example, 33 * 11 * R17, and such an index is interpreted as follows:
- the first digit indicates the outer diameter of the wheel - 33 inches. This indicator is static and convenient to use as it does not depend on the width, as in the European format;
- the second digit is the width of the tread - 11 inches;
- the third carries information about the inner diameter in the 17th. This method is more convenient, because all the indicators are designated separately and do not depend on each other. If you get used to calculus in inches, then select the desired kit becomes easier.
Together with the dimension indicators on the sidewall of tires, other mandatory parameters are deposited - load index and velocity, manufacturer brand, rubber model, production date and maximum allowable pressure.
The presence of color labels indicates prompts when mounting the wheels. The yellow triangle says where the easier place in the sidewall of the chamber tire, which must be combined with a special disc on the disk. The red triangle signals the tight place of the tubeless rubber and is also combined with the corresponding mark.
Additionally, on automotive tires, you can see different labeling and pictograms indicating seasonality, (4 season, all season), the direction of rotation of the wheels (Rotation + arrow), the marking of the external or inner side (Outside or Inside) for rubber with the asymmetric protector. All these indicators, including the load index, will help calculate and select the shoe shoe shoe, and will also be able to guarantee a safe ride.
Load designation
One of the most important parameters is the tire load index. This indicator is denoted maximum masswhich must withstand the tire. The markings of the load index marking is expressed in the numerical value and is located near the wheel dimension.
Therefore, when choosing rubber worth it is for this indicator. For the competent calculation, the value of the load index should take into account the full mass of the machine in the presence of luggage and passengers in the cabin.
Separately, you need to remember about some nuances. For example, the wheel can correspond to the load capacity, but due to the uneven distribution of luggage or passengers, the load may exceed the permissible limits. Therefore, it is worth a renowning and take a set with a higher indicator. This will provide an additional margin of strength and will allow you to be confident on the road.
Sometimes the tire load index has a double value that is written through a hyphen. This means that the wheels are organized for cars with a paired tire mounting. The first number on the tires indicates the load indices in the single state, the second is in the parsen. For example, the numbers 106 * 102 mean that if you use a tire in a paired form, then the maximum load will be 850 kg, and with a single wheel setting it can withstand 950 kg. 
You can often find additional designations next to the tire load index in the form of a LITER EL, which is decrypted as Extra Load or the words reinforced. Such tires are distinguished by a reinforced structure that implies additional layers of the Cord and Brecker. Marking of these sets occurs somewhat differently. To the specified loading index on tires it is worth adding 3 other units.
It should also be remembered that the calculation of the vehicle load index coefficient is carried out on the basis of the limit pressure in the wheels. Information on how pressure should be in the tires are contained on the side of the product, closer to the inner circle. The parameter is measured in atmospheres or kilopascals.

Selection of high-quality and safe rubber
Another important indicator to which is worth watching when choosing rubber, in addition to the tire load index, is the speed index. It is denoted by the Latin letter and means extremely permissible speed Selected set. Speed \u200b\u200band load indicators are indicated together and affect each other. The more loading capacity, the greater the safety margin.
Minimum value acceptable to modern cars - N. This implies that the maximum speed on which you can move is 140 km / h. Car Movement S. specified speed Over the course of several hours does not damage the structure of the tread. Excess this speed parameter will lead to serious wear of rubber and possible damage to the wheel.
Every 10 km / h, the kit receives the following letter, closer to the end of the Latin alphabet. If you want to move on high speeds On good roads, the tires must have an index H, V, W or Y.
For winter tires This indicator is not so relevant. Conditions of the car do not allow to develop the maximum speed. Therefore, it is worth understanding that it is necessary to repel from the class of auto and choose the winter set, based on the tread pattern and the features of operation and weather conditions.
The same is relevant, if you think what index for an SUV is best suited. It is preferable to abandon high-speed tires in favor of rubber with a large load index. The full classification of the tire speed index is presented below.
| Table tire | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|

In conclusion, it is worth saying that new tires It is better cling to the coating than old, worn tires. The load index of such products can also become less with age. Therefore, how to better fill fresh liquids in a timely manner for the full work of all systems, it is more preferable to change the tires every three years.
On tires, in addition to information about the manufacturer, you can find many interesting labels, regarding the size, carrying capacity, tire designs and other parameters, are sufficiently important when choosing automotive rubber. Consider the most common tire marks.
Standard tire marking
In this case, the number 185 will mean tire profile width in millimeters.
The number 60 in the world is considered the tire profile height. However, this is not quite true. In fact, it is indicated here the ratio of the height of the tire profile to its width in%. For our roads, tires are most suitable with a ratio from 65 to 75%. The smaller this number, the lower the tire profile, and the more difficult it is to operate in the conditions of non-ideal domestic roads.
The width and height of the tire profile is of great importance for the chassis of the car. When installing a tire of greater height and width, the car will be softer, the likelihood of damage to the disk decreases, the load on bearings and suspension decreases. Semit wide tires For your car, you will get: good contact car with road coating, good turning on significant speed, improved acceleration and braking characteristics. But the disadvantage in this case is a high price, an increase in fuel consumption, as well as a slight increase in weight, especially in vehicles with low-power engine (up to 1-1.5 liters). In general, wide tires are suitable for a quick and powerful machine, and not for urban minor.
"Z" indicates that this tire is designed specifically for speed movement (more than 240 km / h). On ordinary unordinated tires, the letter "Z" is missing.
14 - that's inner tire diameter In inches, in the place where the tire matches the rim of the wheelbarrow (landing diameter). In this case, the landing diameter of the bus 14 inches and the wheel drive for it should be selected the same diameter. Cm. .
Digit 82 is load index Tires (extremely permissible load on the wheel), defined in accordance with the diagram of "Industrial Standard bandwidth With maximum load. " The tire with an index 82 will safely withstand 1047 pounds (475 kg). Four tires together can carry a fully loaded car, the total weight of which is as much as possible to 4188 pounds. (1900 kg). In most cars on the door jacket from the driver there are information on the carrying capacity of a specific vehicleas well as about suitable for this car Tire sizes.
Letter N is speed \u200b\u200bindexwhich can be marked with the following letters: L (up to 120 km / h), M (up to 130 km / h), n (up to 140 km / h), q (up to 160 km / h), s (up to 180 km / hour), t (up to 190 km / h), u (up to 200 km / h), h (up to 210 km / h), V (up to 240 km / h), w (up to 270 km / h), y ( up to 300 km / h). The letters of speed category indicate the maximum safe speed that the tire is capable of making ideal conditions over a long driving period.
"XL" or "Extra Load" - reinforced tires Among the tires of its size.
American tire marking in millimeters and inches. Translation of American tire sizes to European
American tires are sometimes marked as European - species 185/60 ZR14.. However, the figures are set, for example P 185/60 ZR14. Moreover, the letter R denotes tires for a passenger car . Lt. (Light Truck) denotes tires for jeeps, pickups and small-sized trucks. T. - Spare or temporary tires. Note that these characters are put only on american-made tires.
American tires manufactured for domestic market The United States is marked in inches. American marking in this case looks like 32x12.5 R17where 32 is the width of the profile of the tire in inches, and 12.5 - the height of the profile in inches. What corresponds to the "European" size tires - 320/65 R17.
Additional tire marking
The sign of the umbrella, as well as the labels "Rain", "Water", "Aqua", "Aquatred", "AquaContAct", mean special for confident movement on a wet road.
The "Outside" label shows the outer side tires with asymmetric pattern of tread, and the "Inside" label is internal.
Tire manufacturing date - These are four digits called by oval. The first two digits mean a week, the second two digits - the year of manufacture of the tire. For example, if the date is shown as "0512" it means february 2012..
Concerning domestic tiresAll two indicators are usually affiliated with them: release date and release series.
Colored tires
Colored marks are affixed by the manufacturer of autoresine and carry important information. For tire marking, most often four colors are used - red, yellow, white and blue.
Most often you can see label white color In the form of characters concluded in a small circle. A white marker puts a person checking the compliance of the product issued by the standards. In his own kind, this label is equivalent to the SW icon.
Red marker Carries in itself a double meaning. As a rule, tires marked in this way are used for the factory configuration of the car, as well as a small red circle indicates the most severe area of \u200b\u200bthe bus body.
Labor noticeable yellow marker Indicates a lung part of the tire. This section of the tire must correspond to the position of the spool on the camera. This label is useful for specialists with a tire workshop, as it facilitates the wheel balancing process.
Colored tags used by automotive rubber manufacturers are most often set exclusively for car service specialists. There is no need to know their designation.
Often it is applied to the tire protector along its entire length. colored strips. They are necessary for warehouse workers in order to group the tires of the same size and manufacturer. In addition, color bands demonstrate to the consumer that this tire has not yet been in operation. When driving on the car, these bands simply are erased about the road surface.

Tire Protectors - Classification, Figure, Features
From right choice The shoes for the car depends a lot. Deciding on the purchase of a kit can be guided by various comparative tests. However, it is worth remembering that their characteristics must comply with the operating conditions. In this case, the information indicated in the label on the sidewalls of the tire will help. Such inscriptions on the tire talk about the size of the products and its technological characteristics. Below we will conduct decoding of characters and try to figure out what the numbers and letters in the marking of rubber mean.
In the marking of tires there are mandatory and optional notation. So, on each tire, the manufacturer will be indicated, the brand of rubber itself and the tire sizes. The designation of three digits on the tires indicates the dimension of the disc in inches, the width of rubber and the height of the profile. The numbers are located on the outside.
We have a wheel with parameters, for example, 195 60 R16. This means that we have rubber, the tread width of 195 mm. The second number is the ratio of the height of the drawing to width. The more this parameter, the more the "cazing" there will be rubber. Usually this value is called the profile indicator.
The third digit is an index of the inner diameter of the tire in inches. In general, the widespread error is that motorists acquire wheels, not paying attention to some data on the change in external parameters. For example, size 185 65 R15 will differ in height from 210 65 R15 with the same landing diameter. The ratio of the profile to the width in our case can interfere with the autoresine installation by car. This factor should be understood and take into account. And correctly calculate the sizes of tires will help a special calculator.
Speed \u200b\u200bindexes
Also, the manufacturers of tires are mandatoryly supply all tires by the speed index. This sign can be found immediately after the wheel size indicator. He talks about what limit speed you can move on the roads. Correctly read this sign will help the table, decrypting the speed of the speed of passenger cars.

Load indices
Immediately behind the velocity index on the car's tires there is an index of a permissible load on each wheel. For example, tire marking contains an indicator 88T. This suggests that the car can move with maximum speed 190 km / h, and the maximum allowable load on each wheel is 560 kg.
On certain tires, you can meet the symbols in the form of letters XL or the words are reinforced. Such label is usually awarded autoresin, the load index of which is higher, standard values. If the sidewalls of the XL or Extra Load are written in the figure 88, then it is worth adding to the value 3. Those. Decrypt this indicator is as 91 or 615 kg per wheel.
| Digital designation | load in kg One wheel for passenger cars |
|---|---|
| 60-70 | 250-335 |
| 71-80 | 345-450 |
| 81-90 | 462-600 |
| 91-100 | 615-800 |
| 101-110 | 825-1060 |
| 111-120 | 1090-1400 |
| 121-129 | 1450-1850 |
Deciphering American Size Note
American tire manufacturers Resort to another tire marking. The first one is very similar to European only before the dimension of the additional letters P - the passenger, Lt - a light truck or T - truck. For example, 185 R14C P means that this is a wheel with a tread width of 185 mm, a diameter of 14 inches and intended for passenger cars.
The second system of classification of its products has a completely different look. If a european system Measures the dimensions of automotive tires in millimeters, then American - in inches. However, it is simple enough to understand. For example, there are numbers on tires 27 * 11 * R15. The first number means the outer diameter of the tire, the second - the width of the tread, and the last value is the inner diameter.
Tire marking color marks
To facilitate the installation of wheels on wheel disksManufacturers sometimes equip additional color marks that carry their own information. About how to decipher such icons is lower.
Yellow tire marking
Sometimes on the tires you can find a yellow point or triangle that means the easiest place on the tire When installing, you must combine the mark with the most difficult part of the disk to facilitate balancing.
Red rubber marking
Additional tire parameters include the symbols of a red circle or triangle, which can be found on the sidewall rubber. This is the designation of the tight place of the tire wall. It must be combined with the "L" mark on the disk.
White stamp with digit
The white stamp with a digit, located on the outer sidewall, carries information about the inspector, which carried out the final "acceptance" of the goods.
Colored strips
Some tires are equipped with radial colored stripes. They help identify tires for those or other brands in the store, search for them faster in stock. Sometimes the color of the strip speaks of the date of release or the country by the manufacturer, and also indicates the passage of running.
Additional inscriptions on the sidewall tires
On many passenger tires, in addition to the designation of the model and the type of tread, there is an additional marking:
- the letter R suggests that the Rubber of the Radial Design - the older models are indicated by other letters;
- the presence of STEEL's word in construction means the presence of a metal coordination;
- E in the circle indicates an agreement on the European requirements of ECE;
- Aqua - tires, with improved behaviors on wet asphalt and in Aquatred Aquacontact Rain;
- TL (Tubeless) - besleless tire, in the absence of this labeling, there is a chamber;
- Outside - outer side Installations. Differs from inner side with the asymmetric protector. Will help to figure out which side should be outside when installing a set of rubber on a car;
- DOT - compliance with the requirements of standardization countries;
- Rotation - applied to sets with directional pattern. Wheels should rotate in the direction indicated by the arrow;
- Treadwear - Wire Resistance Indicator. On many tires, wear marking is performed in the form of the grooves. The increased number of layers is indicated by the letter C;
- RF (RUNFLAT) - Rubber with enhanced cord. It is capable of arriving more than 80 km at low pressure - 0 atmospheres. There are cases when both punched wheels have nicely kept the road at speeds up to 80 km / h.
Seasonality
It is also worth understanding what seasonal icons on wheels mean.
- Winter - Winter Tire Designation. It is characterized by a soft composition of rubber, and some tires are equipped with spikes, 1.6 mm high, providing the best tap on the icing road;
- m + S badges are found on many winter and summer sets. This marking indicates MUD + SNOW. Tires have a pronounced drawing and are able to behave well in the conditions of bad weather. However, universal rubber behaves worse than specialized sets.
Manufacture date
Next to the place of the sizes of the wheels there are four more digits that indicate the date of the manufacture of the kit. Read it is quite simple if you understand the calendar. The first two digits are the sequence number of the week, and the second is the year of production. That is, number 4215 suggests that the kit has been produced at the 42nd week of 2015.
Permissible loads
A few more words about how to read the index of permissible load. To achieve the maximum value, the pressure must also be maximum. The designation is given in pounds per square inch and designated as Max Pressure on the sidewall of the tires.
