Q:The left rear tire side of the car scratch, need to change it?

Tire pressure is too low or too high, will affect the service life of tires. If the tire pressure is too low, the radial deformation increases, the deformation of both sides of the tire wall is excessive, resulting in two wear of the crown of the tire, so that the temperature of the tire increases, will seriously reduce the service life of the tire.If the tire pressure is too high, increased tire stiffness, deformation and ground area is reduced, so that the central unit tread pressure increases, the wear of Caroline drama. Produces a crown wear phenomenon that affects comfort and reduces tyre life. Tests have shown that if the pressure is increased by 25%, the tire life will be shortened by about 30%.

Q:How often will the new car be inflated?

It's usually oxygen, and the advanced cars in the 4S repair shop seem to be nitrogen, which is said to be more stable and less corrosive to the tires. The street can be added, as long as you pay attention to the tire pressure, the car in the car door or fuel tank lid will have the air pressure logo.

Q:Which brand is the best for truck tires?

For example, the domestic tire ZhengXin Chaoyang, shuangqian, etc. these qualities can be universal, the same high price

Q:What are the sizes of the tires for big trucks?

PR is the meaning of hierarchy, which refers to the nominal number of plies in the tire rubber layer, which is not consistent with the actual ply number. It is an important indicator of the tire strength. Levels are marked in Chinese, such as 12 levels. In English, such as "14P.R", that is, the "14 poles".

Q:How to distinguish the tire grades?

Each tire side is engraved with the tire speed symbol (also called speed level), corresponding to the speed symbol, you can know the maximum speed of the tire

Q:The car has a flat tire. How long can it run?

The tyre is not recommended to continue under low pressure. (please check the cause of the tire depression; for example: nail sticking, cutting, rubber aging, cracking, etc.).

Q:Large trucks, tires and wheel heating, and can not find out the problem, the general heat to the number of temperature, tires or wheels will be dangerous situation?

The hub (shaft head) is hot: it may be tight or abnormal wearThe hub is in the inside of the brake drum, which is the axle head that is installed when it is disassembled. The hub (shaft) is hot, usually bearing assembly too tight or lubrication is not good, the temperature is too high will lead to the inside of the grease melt, flow out, affect the brake effect, will burn the bearings seriously. If the shaft is hot, be careful. It may be that the bearings are tight or abnormally worn.

Q:Why should full load trucks bring water to the tires?

The maintenance of freight cars generally need to do the following: first of all, affected by the temperature, the tire gas will automatically expand, in order to ensure the tire pressure, it is recommended summer filling nitrogen, filling pressure should be reduced by 10%. Second, replace tires in time. Summer temperatures will accelerate the wear of tire rubber aging, decreased strength of steel layer, general tire tread gounei raised markers, the owner should timely change. At the same time, the front wheel for the reason of the steering wheel, wear faster than the rear wheel, in order to extend the service life of the tire, you can regularly tire transposition, to balance the front and rear wheel wear. Generally diagonal swap method, so that the tires wear evenly.

Q:What does tyre 82H and 85V mean?

Tire is one of the most important components of automobile, its main function is: all the weight support of the vehicle under car load transfer; traction and braking torque, ensure the adhesion of wheel; vibration and impact mitigation and absorption while driving, prevent the auto parts by the violent vibration and early damage to adapt to the high speed performance of the vehicle, and reduce running noise, ensure driving safety and handling stability, comfort and energy saving economy.

Q:Can truck tires intermodulation on the left and right? Because eat fetal to eat badly

Sure。 You should have a front and rear tire, which is the best way to change sides. Are the front tires, certain quality assurance, the same pattern of tires. Use only.
