As one of the important parts of the vehicle, the tire is not only related to the handling performance of the vehicle, but also related to the life safety of the people on the vehicle. After all, no matter how fast the car runs, it relies on the grounding parts of the four tires. According to statistics, 46% of highway traffic accidents are caused by tire failure. Therefore, we must never ignore the importance of tires. Today, I'd like to invite a senior automobile maintenance expert to tell you something about automobile tires. Experts believe that the "health" of tires is closely related to the air pressure during driving. Abnormal tire pressure will cause local tire wear, reduced handling comfort, increased fuel consumption and other problems, which will lead to a flat tire. Therefore, maintaining the standard tire pressure and monitoring the tire pressure changes in real time are the keys to pre-burst tires.
With the increase of expressways, cars are traveling faster and faster on the road. The high temperature generated during high-speed driving will lead to abnormal tire pressure, which can maintain normal tire pressure for a long time by exhausting the original air in the tire and filling it with dry nitrogen. Because nitrogen is an inert gas, its expansion coefficient is low, and it does not easily change with the change of temperature, so the probability of tire puncture can be minimized. In addition, because nitrogen does not contain water, it can also delay the oxidation speed of the inner wall of the tire. After driving for a period of time, there will be problems such as vehicle deviation, steering wheel sinking and unilateral tire wear, which is caused by wheel alignment angle deviation. At this time, the vehicle should be tested for four-wheel alignment. If it exceeds the allowable range, it should be adjusted immediately.
Replacing tires, wheels or wheels that have been hit by a huge impact will lead to uneven mass distribution of the wheels, and the steering wheel will shake when driving, and the vehicle will bump and sway, which will also lead to increased tire wear. If we want to eliminate this situation, we must do dynamic balance for the wheels. In addition, experts in American auto accessories department stores remind car owners to try to correct bad driving habits such as slamming on the brakes, turning sharply and starting quickly, so as to reduce tire wear and prolong tire service life. In order to ensure safety, in addition to checking the tire pressure and tread pattern, the owner should also pay attention to whether there are the following problems on the tire surface: whether the tread is cracked. The 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 easy to rupture and puncture due to external force impact during driving. Whether the tread is cut or nailed. All these may cause tire leakage and eventually puncture, which will become a safety hazard if not detected in time. After the tire is hit, check whether the tread is bulging in time. If it bulges, it means that the sidewall ply has been broken and there is a possibility of puncture at any time.
