8.25 r20 and 397 is suitable for what. Passenger tires, summer, winter

7.50-20 - bias tire

where 7.50 and 315 are the designation of the nominal width of the tire profile (in inches and millimeters, respectively);

16 and 22.5 - designation of the nominal diameter of the rim (in inches);

R - designation of a radial tire;

80 - series (nominal ratio of height to width of the profile in percent).

195 - profile width in mm

R - designation of a radial structure

16 - landing diameter in inches

All the same only the wheel series is 82% and is not indicated on the tire sidewall

Low Profile Bias Tire

An example of a camera designation:

Example of rim tape designation:

Matching tire designations in inches and millimeters

The designation for bias tires is the same as for radial tires.

There is a designation of tires through their overall dimensions.

For example: 530 / 70-21 (1300x530-533) - Kama-410

In accordance with GOST 5513-97, the following mandatory inscriptions are applied to the tire:

a) trademark and (or) manufacturer's name;

b) the country of origin in English "Made in ...";

c) tire designation;

d) trade mark (tire model);

e) indices of bearing capacity of loads for single and double wheels;

g) "Tubeless" designation for tubeless tires;

i) the designation "M + S" or "M.S" for winter tires;

j) production date of four digits (the first two indicate the ordinal number of the week, the last two - the year of manufacture);

l) pressure index PSI;

m) the designation "Regroovable" is applied to each of the sidewalls only if it is possible to deepen the tread pattern by cutting tires;

m) approval mark "E" indicating the approval numbers and the country issuing the certificate of conformity with UNECE Regulations No. 30 or 54

o) designation of this standard (without year of approval);

p) national mark of conformity for certification of a tire for compliance with the requirements of this standard;

c) serial number of the tire;

r) sign of the direction of rotation (in the case of a directional tread pattern);

y) All steel - for solid steel cord tires;

t) designation "TWI" indicating the location of wear indicators in the shoulder area of \u200b\u200bthe tread;

x) technical control stamp.

American designations: standard size (decoding).

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 - a light truck) are put in front of the standard size. For example: P 195/60 R 14 or LT 235/75 R15.
And another tire marking, which is fundamentally different from the European one.
For example: 31x10.5 R15 (corresponds to the European standard size 265/75 R15)

  • 31 is the outer diameter of the tire in inches.
  • 10.5 is the width of the tire in inches.
  • R - radial tire (older tire models were diagonal).
  • 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.

Color marks used to mark the tire:

Yellow marking on the tire

(round or triangular mark) on the sidewall indicates the lightest spot on the tire. When mounting a new tire on a rim, the yellow mark must be aligned with the heaviest spot on the rim. This is usually where the nipple is attached. This allows for better wheel balance and lighter weights.
On used tires, this yellow marking is not so relevant, since, as a rule, when the tire is worn, its balance shifts.

Red marking (red dot on the tire)

- means the place of maximum power inhomogeneity, the manifestation of which is usually associated with different connections of different layers of the tire during its manufacture. These irregularities are completely normal and all tires have them. But usually only those tires that go to the original equipment of cars are marked with red dots, i.e. when the machine leaves the factory.
This red mark is aligned with the white markings on the rims (white markings on the rims are also placed mainly for the original equipment of the car), which indicate the closest place to the center of the wheel. This is to ensure that maximum tire discontinuity is minimized when driving, providing a more balanced wheel power response. During normal tire fitting, it is not recommended to pay attention to the tire marking with a red mark, but to be guided by the yellow mark, aligning it with the nipple.

White point or white circle

In the case of some first-specification car tires, this color coding indicates the point of minimum radial force deflection (RFV), which is the most flexible point in the sidewall of a car tire. In this case, the white dot or circle must be aligned 180 ° from the "L" mark, or the "top" mark on the wheel.

Marking - white stamp with number

means the number of the inspector who carried out the final inspection of the tire at the factory.

Colored stripes

on the tread, tires are made to make it easier to "identify" the tire in the warehouse. All models of tires and different standard sizes have different markings. Therefore, when tires are stacked in warehouses, it is immediately apparent that the stack of tires is of the same size and model. These colored stripes on the bus have no other meaning.

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.

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- asymmetric tires. 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 to drive a car at a speed of no more than 80 km / h with a FULL pressure drop in the tire (in case of 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 arrow this marking on the sidewall of the tire indicates the directional tire. When installing the tire, the direction of rotation of the wheel indicated by the arrow must be strictly observed.

Tubeless- 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 camera.

Max Pressure - the maximum admissible pressure in the tire, in kPa.

Max Load- the maximum permissible load on each wheel of the vehicle, in kg.

Reinforced or letters RF in a standard size (for example 195/70 R15RF) means that this is a reinforced tire (6 layers). The letter C at the end of the dimension (e.g. 195/70 R15C) denotes a truck tire (8 layers).

Radial this marking on the rubber in a standard size means that it is a tire of a radial design.

Steel means that 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 Is 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 made in the form of a protrusion with a height of 1.6 mm (the minimum tread size for light vehicles) and is located in the recess of the tread (usually in the drainage grooves).

What do the tire sidewall markings H / P, H / T, A / T, M / T mean?

For four-wheel drive cars and 4x4 SUVs, the following tire categories can be distinguished.

  • H / P (High Performance) - Pure road tires. For driving on asphalt roads. The tires are as close as possible to the tires of a passenger car - for dynamic driving. They have quietness, good grip on a flat highway. The tread is not high, "racing".
  • H / T (Highway Terrain) - For driving mainly on asphalt roads. Road tires. The tread is not high, typical for light rubber. The tire sidewall is poorly protected.
  • A / T (All Terrain) - Universal tires for driving both on asphalt and on light off-road. The tread is more aggressive than the H / T (taller and more grippy), the sidewall is more protected. Designed for asphalt, dirt roads, sand, stone, snow, everyday. All means that the tire behaves well both on and off the tarmac.
  • M / T (Mud Terrain) - Mud in English means mud - off-road tires. The tread is "like a tractor", has side lugs, it is more difficult to clog with mud. The rubber is more oak than A / T and is not very good on asphalt (do not drive on the highway), as well as behaves badly on ice. Designed for: driving on bumpy roads, ruts, clay, wetlands.

Sidewall wear indicator

It is applied to the sidewalls as a rule of bus tires. This sign is nothing more than a sidewall wear index, since the bus must park tightly to the curb near the stop, respectively, in the process of sidewall abrasion, there are numbers that show the degree of wear.

How to find out the date of manufacture of a tire


The date of manufacture of a car tire is written in the form of four digits in an oval (for example 3706) - the first two digits are the week of manufacture, the next two are the year of manufacture (in our example, 37 is week of 2006).

Russian truck tires are marked as follows

Where 3494 is the date of manufacture of the K-letter, 00092 is the serial number of the tire

The 3-digit date code on the tire means it was manufactured before 2000.
The old marking is similar to the new one, i.e. the first two digits are also the week of manufacture, but the last digit does not mean the entire year, but only the last digit of the year.

For example, code: 108. This means that the tire is produced: 10th week 88 or 98 years.
To understand the 80s or 90s, you need to carefully look whether there is a space after these numbers (gap or triangular stamp) on the sidewall or not.
If not: * 108 *, then this is 88, but if there is: * 108 * or * 108 (the icon is a triangle) *, then this tire is 98th year of production.

Such difficulties are due to the fact that previously tire manufacturers did not think that the tire would be used for more than 10 years. But after 2000, tire manufacturers came up with a more convenient 4-digit production date marking on the wheel.

The following inscriptions and designations are applied to the camera and rim tape:

a) product designation;

b) trademark and (or) manufacturer's name;

c) designation of this standard (without year of approval);

d) production date of four digits (the first two indicate the ordinal number of the week, the last two - the year of manufacture);

e) technical control stamp;

f) BC - for chambers made of butyl rubber.

In our store you can find out. We always have unmatched quality, trained staff, and great prices!

All truck tires presented in the catalog of our online store comply with high quality standards and are covered by the manufacturer's warranty.

The total number of found commodity items in the amount of 8.25-R20 is - 14 pcs. The cost of the cheapest truck tire in this standard size is only 6110 rubles. ... Premium brands are somewhat more expensive in price, since the final cost is influenced by innovative technologies used in the production of rubber and high-quality components that make up the rubber compound. Maximum cost of a truck wheel R20 8.25 in Moscow will be RUB 6110.

Truck tires 8.25 r20 can be designed for driving or steering axles. Some standard sizes can be mounted on a trailed axle. When choosing a truck rubber, pay attention to the characteristic "Axle of application" in which the type of tire is indicated. The parameters also indicate the purpose of using the rubber, its ply content, country of production, and speed and load indices.

Be sure to check the 8.25R20 Truck Tire Photos, Ratings, Features, Customer Reviews and Prices before buying. You can pay for your order either in cash or by bank transfer. The price is indicated for one tire and is automatically recalculated when the quantity changes.

All presented products are available for ordering and delivery in Moscow after placing and paying for the order.

According to the rules of the road, tires on passenger vehicles must be changed when they do not exceed 1 mm. It is also mandatory to switch from summer tires to winter tires with a decrease in the average daily temperature. Therefore, any driver is interested in buying high-quality rubber that will last a long time, while providing good grip on the road surface.

To get complete information about a particular tire, just look at its sidewall, where the marking is located.

The most important parameters that interest the car owner:

  • standard size;
  • manufacturer;
  • speed and load indices;
  • seasonality - winter, summer, all-season tires.

Standard size

The standard size for passenger cars is indicated by metric markings: 185/70 R13 or 205/55 R 16. Usually, drivers know what size they need. The same numbers and letters mean the following (for example 205/55 R16):

  • 205 - width in millimeters;
  • 55 - the ratio of the width and height of the profile (205 multiplied by 0.55 is equal to 112 millimeters). That is, in this case we are dealing with a low-profile sports type tires;
  • R16 is the rim diameter, it also corresponds to the diameter of the disc in inches.

If we are talking about truck tires for domestic cars, then ordinary marking in millimeters is often used:

  • 240x508 (240R508) - wheel for GAZ-3307 or PAZ;
  • 300x508 - MAZ or KamAZ wheel.

In America, dimensions are indicated in inches:

  • 31x10.5 R16;
  • 8.25R20 (analogue 240x508).

Please note: if before the size of the bore diameter is English. the letter "R" means that the tire is a radial type. If there is a hyphen instead of a letter, it is diagonal. Radial tires are more suitable for driving on hard surfaces, while diagonal tires are usually used for row-crop tractors, mining trucks and off-road vehicles.

Tire technical parameters

The type of rubber should be appropriate for the weight of the vehicle and its speed characteristics. This parameter is displayed as follows: 112H or 88T. In this case, we have:

  • H - speed index (up to 210 km / h).

    • In any auto shop, you will find a plate where these parameters are indicated. Let's just say that the lowest speed index for modern passenger cars is "Q", corresponding to a speed of 160 kilometers per hour. These values \u200b\u200bcan be selected with a small margin. If the stock is too large, then the rubber will be too stiff.

    Seasonality

    Rubber must be selected for the season:

    • snowflake - winter tires;
    • M + S (Mud and Snow) - the tire retains its qualities when driving on snowy or muddy roads;
    • All Seoson is all-season.

    If you see an umbrella or the words "Rain", "Water", "AquaContact" - rubber for driving on wet surfaces.

    date of manufacture

    An important parameter. According to GOST, tires should not be stored in the warehouse for more than five years. Even one year of storage is negatively reflected in the performance. The year of production is indicated in this way - 3614, 1215, 0513 and so on. The first two digits are the week number, the second two are the year. That is, if, for example, 2412 is written, it means that the rubber was made around May-June 2012 and it is better to look for something fresher.

    Other marking

    There are many other inscriptions on the tires:

  • allowable pressure (Max Pressure);
  • Rotation - which direction it rotates;
  • Inside, Outside - inside or outside (indicate rubber with an asymmetrical tread pattern);
  • Traction - coefficient of braking on a wet canvas (A, B, C);
  • TT, Tubeless - tubeless tires.

    • Knowing these designations, you can easily find the perfect tires for your car.

    What are the letters? what are the numbers on the wheels? We read, we are enlightened ...



    The description of any tire model contains the values \u200b\u200b" SIZE"And" INDICES».
    For instance: 195/65 R15 91T
    Let's decipher these values:
    195 - tire width in mm.
    65

    R15 - value 15 MEANS DIAMETER in inches !, not RADIUS! and beech R

    15
    91 - index of the maximum load per tire in kilograms.

    Some tires say MAX LOAD (maximum load) and then the values \u200b\u200bare in kilograms and pounds.

    Index 91 corresponds to the load 615 kg on one wheel.

    For vans and light trucks, special, multi-layer reinforced tires with high load indices are produced. And they are indicated depending on the load index - by the inscription REINFORCED (6 layers, reinforced tire) or the letter " FROM»After the tire diameter, for example: 195 / 70R15C, (8 layers, truck tire).

    T - speed index - the maximum permissible speed in km / h.

    Additional marking used by tire manufacturers.


    M&S (Mud + Snow - Mud Plus Snow) - This marking on a tire indicates that the tire is specially designed for winter or all-season use.

    All Season - An all-season tire designed for year-round use.

    Rotation - A directional tire, the direction of rotation of which is indicated by an additional arrow on the sidewall of the tire.

    Outside and Inside (or Side Facing Out and Side Facing Inwards) - Asymmetrical tires, when installing which you must strictly follow the rule of installing the tire on the rim. Inscription Outside (outside) should be on the outside of the car, and Inside (inner side) - from the inner.

    Left or Right - Means that the tires of this model are left and right. When installing them, you must strictly follow the rule of installing the tire on the car, the left ones only on the left, and the right ones, respectively, only on the right.

    Tubeless or TL - Tubeless tire. If this inscription is not in the marking, then the tire can only be used with a tube.

    Tube Type or TT - The tire must be operated with a tube.

    MAX PRESSURE - The maximum admissible pressure in the tire, in kPa.

    PSI - Pressure index from 20 to 85 (only for tires with the index " FROM»).

    Steel - Designation of the presence of a steel cord.

    E enclosed in a circle - Tire complies with ECE R30 (ECE regulation).

    DOT - American safety standard.

    XL or Extra Load, EL - Reinforced tire with increased load capacity.

    RAIN, WATER, AQUA (or the umbrella icon in the tire sidewall markings) - Indicates that these tires are specially designed for rainy weather and have a high degree of aquaplaning protection.

    TWID - Projector wear indicator pointer. The indicator itself is a protrusion at the bottom of the tread groove. When the tread wears down to the level of this lug, it's time to replace the tire.

    Energy - Tires with low rolling resistance, characterized by reduced fuel consumption.

    American size designation.


    There are two types of American tire markings.

    The first one is very similar to the European one, only the letter “ P» ( Passanger - for a car) or the letter " LT» ( Light Truck - light truck). For instance: P 195/65 R 15 or LT 185/75 R 16.

    And another marking, which is fundamentally different from the European one.

    For instance: 31x10.5 R15
    Let's decipher these values:
    31 is the outer diameter of the tire in inches.
    10.5 - tire width in inches.
    R - radial tire.
    15 is the inner diameter of the tire in inches.

    Truck tire marking


    Truck tire marking - radial


    For instance: 10.00R20 146 / 143M
    Let's decipher these values:
    10.00 - Width of the tire profile (in inches); .00 - designation of a full-profile tire for trucks.
    Also the width can be: 6.00 or 8.25 or 9.50 etc. - Tire section width (in inches) - This is also a full profile tire.
    R - Radial.
    20 - Mounting diameter of the tire (in inches).
    146/143 - Load index. 146 - for a single wheel, 143 - for doubles (load on each wheel). (see table of load indices). The difference in the indices of double and single wheels is due to safety reasons, in case one of the four wheels on the axle fails, the remaining tire could withstand the additional load.
    M - speed index - maximum permissible speed in km / h. (see table of speed indices). Letter M corresponds to a maximum speed of 130 km / h.
    Marking 146 / 143M means that with a single busbar the carrying capacity of the tire is 3000 kg, and with a double busbar - 2725 kg at a maximum speed of 130 km / h. At the same time, if the car is moving at a lower speed, the bearing capacity of the tire can increase, in other words, the car can carry more weight.

    Values \u200b\u200bmay also be present ns12, ns14, ns16 and others - tire ply. The number is the number of layers.

    For instance: 385 / 65R22.5
    385 - tire profile width in mm.
    65 - the ratio of the height of the tire (from the landing rim to the outer edge of the wheel) to its width in percent.
    R - radial cord construction, the cord threads in the carcass plies have a radial (meridional) arrangement, i.e. directed from side to side.
    22,5 - mounting dimension of the rim in inches (1 inch \u003d 2.54 cm).
