Why do car tires have flat tires?

1. High temperature: The temperature is high in summer, and there are more puncture incidents than in other seasons. High temperature is one of the main causes of puncture. Because of thermal expansion and cold contraction, the tire is easy to deform when the car is driving at high temperature. If it can't stand it, the tire will burst.

2. Unstable tire pressure: If the tire pressure is unstable, whether it is too high or too low, it will easily lead to a puncture. Insufficient tire pressure may cause the sidewall of the tire to be squeezed during driving, which may lead to a puncture. However, if the tire pressure is too high, the friction of the tire will increase, which will bring more pressure to the tire and easily lead to a puncture;

3. Improper maintenance: In daily life, tires also need maintenance. If the tires have not been adequately maintained for a long time and the car has not been overhauled, the tires will easily age, and improper maintenance will also increase the probability of puncture.

Ways to prevent tire puncture: avoid the vehicle being in a high temperature environment all the time. Try to park in a cool underground garage in summer, check the tire pressure regularly and maintain the vehicle regularly;

4. The tire surface is excessively worn or corroded by oil, resulting in a puncture. Many vehicles have the problem of excessive tire surface wear, and some tire patterns have been smoothed. The bearing capacity and compressive strength of this kind of tire are much lower than those of ordinary tires, so it is difficult to maintain the normal running of the car. In addition, high temperature, overspeed, road bumps and other factors are also likely to lead to flat tires. Million car purchase subsidy
