    Tire safety inspection is the most important tire pressure monitoring is the key

    As one of the important components of the vehicle, the tire is not only related to the handling performance of the vehicle, but also to the safety of the personnel on the vehicle.

    As one of the important components of the vehicle, the tire is not only related to the handling performance of the vehicle, but also to the safety of the personnel on the vehicle. After all, no matter how fast the car runs, it relies on the grounding of the four tires. According to statistics, 46% of traffic accidents on expressways are caused by tire failures. Therefore, we must not ignore the importance of tires. Today, I would like to ask experienced car repair experts to tell you about car tires.

    Experts believe that in the driving of the car, the "health" of the tire is inseparable from the air pressure. The abnormal tire pressure can cause local wear of the tire, reduced comfort of the control, and increased fuel consumption, resulting in a puncture. Therefore, maintaining the standard tire pressure and monitoring the tire pressure change in real time is the key to preventing puncture.

    With the increase of highways, cars are driving faster and faster on the road. The high temperature generated during high-speed driving will cause abnormal tire pressure, discharge the original air in the tire, and fill with dry nitrogen to maintain normal tire pressure for a long time. Because nitrogen is an inert gas, the coefficient of expansion is low and does not easily change with temperature, which can minimize the chance of puncture. In addition, since nitrogen does not contain moisture, the oxidation rate of the inner wall of the tire can be retarded.

    After driving for a period of time, there will be problems such as the deviation of the vehicle, the sinking of the steering wheel, and the wear of the tire on one side. This is caused by the offset of the wheel alignment angle. At this time, the vehicle should be tested for four-wheel alignment. If it is outside the allowable range, adjust it immediately.

    When a tire, wheel or wheel is replaced, the quality of the wheel will be unevenly distributed. The steering wheel will feel jittery when driving, and the car will be bumped and swayed, which will also cause the tire to wear more. If you want to eliminate this situation, you must balance the wheels. In addition, the car accessories department store experts remind owners should try to correct the bad driving habits such as slamming on the brakes, sharp turns, fast start, to reduce tire wear and extend tire life.

    In order to ensure safety, in addition to checking tire pressure and tread, the owner should also pay attention to the following problems on the tire surface:

    Whether the tread is cracked. Tire rubber will harden and crack after aging, which indicates that the tire has reached the replacement limit, the tire grip is reduced, and the cracked part is easily broken and burst due to external impact during driving.

    Whether the tread is scratched or pinned. These may cause the tire to leak and eventually puncture, if not detected in time, it will become a safety hazard.

    After the tire is hit, check the tread for bulging. If the drum is wrapped, it means that the sidewall ply has been broken and there is a possibility of puncture at any time.
