Extended Materials. Tires are one of the most important components of a car, and its main functions are:

1. Support the full weight of the vehicle, bear the load of the car, and transmit the force and torque in other directions;

2. Transmit the torque of traction and braking to ensure good adhesion between the wheels and the road surface, so as to improve the dynamics, braking and passability of the car; Together with the automobile suspension, it mitigates the impact of the car when driving, and attenuates the resulting vibration;

3. Prevent auto parts from severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

Installation process: 1. Please use standard wheels, do not use deformed or damaged wheels.

2. Before combining the rim and tire, please clean the rim and tire, and no debris should be left inside.

3. Before the combination of the rim and the tire. Use rubber lubricant or soapy water to wipe the rim flange of the tire lip, do not use oil-based lubricants.

4. When combining the rim and tire, pay attention to the mating situation, and do not use the wind pressure beyond the normal range to force the installation, so as to avoid danger.

5. The combination of the rim and the tire needs to be operated by the special personnel of the tire line, please do not combine it by yourself.

235--- tire cross-sectional width 235mm

55--- percentage of tire thickness to tire width.

R--- radial tires.

The rim diameter of the 18--- is 18 inches.

With a load index of 100 ---, the maximum load of this tire is 800 kg.

--- speed class, the tyre has a top speed of 210 km/h

235 is the unit of cross-sectional width mm

55 is the flat ratio (the tire section is high, the tire section is high).

R--- radial tires.

18 rim diameters in inches.

215 = cross-sectional width copy of 215 mm, 55 = aspect ratio of bai55%, r = radial tire structure, 18 = rim diameter of 18 inches

The size of the tire is printed on the wall, and there are two ways to express it, such as 34*7 or so on. The former is a high-pressure tire and the latter is a low-pressure tire.

There are also many symbols, such as D for light cars, F for mid-size cars, G for standard cars, and H, L, and J for large luxury and high-performance cars. If an R is printed on the sidewall, such as 175R13, it means that the tire is a diameter tire, with a width and length of 175mm, which is inches, and it is installed on the wheel with a diameter of 13 inches on the wheel, and the word radial is generally engraved.

1. Answer: 215 meaning.

Du Si is the cross-sectional width of the tire zhi degree zhi degree, 55 means the flat ratio of the tire, the flat ratio is the percentage of the tire section height divided by the tire width, r means radial tire, 18 means rim diameter is 18 inches.

3. English expression: tire size

4. Unit: mm 5,

215 represents the cross-sectional width of the tire 215 mm, 55 represents the flat ratio of the tire, which is the percentage of the cross-sectional height of the tire divided by the width of the tire, r represents the radial tire, and 18 represents the rim diameter of 18 inches.

Rim diameter 18 inches ......The cross-section of the tire is 215 mm and the aspect ratio is 55

The meaning is as follows: 235: the tire width is 235 mm; 55:

It is called the flattening rate of the tire, which means: the ratio of sidewall height (sidewall) to tire width is 55%; R: Wire radial tires, 18:

The diameter of the hub is 18 inches. Tire is one of the most important components of the car, its main functions are: to support the full weight of the vehicle, to bear the load of the car;

Transmit the torque of traction and braking to ensure the adhesion between the wheels and the road surface; Reduce and absorb the vibration and impact force of the car when driving, prevent the auto parts from being subjected to severe vibration and early damage, adapt to the high-speed performance of the vehicle and reduce the noise during driving, and ensure the safety, handling stability, comfort and energy-saving economy of driving.

235 means the cross-sectional width of the tire 235mm; 55 represents the flat ratio of the tire, which is the percentage of the cross-sectional height of the tire divided by the width of the tire, the greater the value, the thicker the tire, the lower the maneuverability, but the comfort will increase; r stands for tire type, radial tire, and 18 for rim diameter 18 inches.

Since tires have a certain lifespan, it is also very important to pay attention to the production date. The production date is generally on the outside of the tire and has four digits, the first two digits indicate the number of weeks, and the last two indicate the year of production. Therefore, 3410 indicates that it was produced in the 34th week of 2010.

235 represents the cross-sectional width of the tire 235 mm, 55 represents the flat ratio of the tire, which is the percentage of the cross-sectional height of the tire divided by the width of the tire, R represents the radial tire, and 18 represents the rim diameter of 18 inches.

Width 235 and height 55R indicate that radial tire 18 is the size.

235: Nominal size of the cross-sectional width (mm).

Tire section width refers to the maximum distance between the two outer sides after the tire is inflated according to the regulations, which is generally divided into 5mm units, but the tolerance of the new tire section width is 63%.

55: Flat rate (%)

The aspect ratio is a piece of data for tires, which refers to the percentage of the height of the tire's cross-section to the maximum width of its cross-section, which is simply the height-to-width ratio of the tire.

r: Tire structure: radial.

Radial tires are a structural form of tires, which are different from bias tires, arch tires, pressure-regulating tires, etc. The international code for radial tires is "R", commonly known as "steel wire tires".

18: Adapted hub diameter (inches).

They are the width of the tire. The flat ratio also has steel rims.
