If the automobile is a double-tire automobile, the effect similar to load overload can be generated because one tire is under insufficient air pressure and is under low stress, and the other tire is under high stress, and the result is also serious.
The tire is deformed and hardened due to the overhigh inflation pressure, and the tire is seriously cracked inwards when the tire is not timely relaxed under the action of sudden vibration impact force, so that the instant tire burst is caused. Too high inflation pressure can also lead to the tire shock absorption shock-proof ability to worsen, easily damages the electronic parts of the bottom of the automobile, also worsens the braking performance, is a hidden danger of tire burst. The inflation pressure of a certain tire in the front left and right of the automobile is too high or too low, so that the stress of the front two wheels is unbalanced, and the direction of the automobile turntable operated by a driver is unstable. The inflation pressure of a left tire and a right tire behind an automobile is too high and too low, so that the stress of two rear wheels is unbalanced, the high-pressure tire is overloaded, the overload phenomenon is similar, and the tire abrasion is accelerated or the tire burst occurs. The traditional tire pressure monitoring system only monitors the tire pressure of the tire, but when the automobile tire is used to a certain age, the tire wear is aggravated, the automobile is accelerated, particularly the cross-country vehicle is accelerated violently when playing cross-country vehicles, if the acceleration of instantaneous acceleration is not controlled, the risk of starting and tire burst is also caused very easily, and therefore the monitoring system which can reliably monitor the tire pressure of the tire and the acceleration is needed.
