Most car owners know the danger of a puncture, but do not know the daily maintenance of the tire. Which tire pressure is maintained by the tire. In fact, the tire pressure is very special. It can’t be too high or too low. It should be treated differently in different seasons. In addition, the wear of the tire is also limited. If you find that the tire is worn, you must change the tire in time, master the tire knowledge, and even save fuel consumption. Safety.

Use the appropriate tire pressure

The tire pressure of a car must be appropriate, neither too high nor too low, but how much is appropriate? In fact, all car manufacturers have special regulations on tire pressure, please follow the mark not to exceed the maximum. Too low or too high tire pressure can affect the life and fuel consumption of the tire itself. Excessive tire pressure will concentrate the car’s weight on the center of the tread, causing the tread center to wear quickly. The tire pressure is too low, resulting in an uneven tire grounding area, increased wear, increased rolling resistance, and increased fuel consumption.

The left and right tire pressures should be the same. When the pressure on one side of the tire is too low, the vehicle will go to this side during driving and braking. At the same time, it should be noted that the two tires on the same axle should have the same pattern specifications. Different manufacturers and different patterns of tires should not be used for the two front wheels at the same time. Otherwise, the deviation will occur.


Pay attention to tire life

Tires are naturally worn, so the factory tires are marked with wear limits on the sidewalls before leaving the factory to indicate the real-time wear of the tires. Regularly check the wear of the tires during daily use to prevent serious wear and tear on the tires. Tires will also age. Generally, the life of a normal tire is 4-5 years. After 5 years, even if the wear of the tread is small, it is best to replace it.

In some cases, some owners have complicated road conditions and tires are severely worn. If there are punctured tires, they have been repaired three or four times. It is best to use this type of tire to switch to a non-drive wheel or a rear wheel to reduce the risk of puncture.

Although the tire pressure should be suitable, it should not be too high or too low. However, the tire pressure cannot be kept constant, and it must change with the seasons and road conditions. In winter, the tire pressure should be increased appropriately. In winter, the outdoor temperature is low. The tire pressure will also be reduced by expansion and contraction. If the tire pressure is not properly increased, it will not only increase the fuel consumption of the car but also accelerate the wear of the car tire. Generally, when driving on a highway, the tire pressure should be increased by 10% to reduce the heat generated by friction, thereby improving the safety of driving. Therefore, appropriate tire pressure is different in different seasons. The car mainly changes the tire pressure of the car tires with the change of seasons, prolonging the service life of the tires.
