Talk about the feeling of nailing the wheel.

First, I am anxious and flustered, and then I try to remedy it, such as calling someone to ask for leave, and then pushing the cart to change the tire.

1. When the tire is punctured, you must get off and check. Generally, cars with abundant configurations now have tire pressure detection systems to detect whether the tire pressure is within the normal range (you usually prepare a simple one) and below the normal range. Suggest immediate measures.

2. If the air leakage is not serious, you can temporarily replace the spare tire and drive to a nearby repair shop at a low speed to repair the tire or replace it with a new one.

3. The air leakage is serious. I have experience in changing tires. I can change the spare tire myself to ensure driving safety. Generally, spare tires should not run at high speed, and the tires should be repaired and replaced in time.

First, the cause of puncture

1, it is a flat tire. When the tire is punctured by nails or other sharp objects, the tire will leak air, which will lead to a puncture.

The tire pressure is too high. Because the car runs at high speed, the tire temperature rises, the air pressure rises, the tire deforms, the elasticity of the carcass decreases, and the dynamic load on the car also increases. In case of impact, internal cracks or puncture will occur. This is also the reason why a puncture accident will occur in summer.

3. The tire pressure is insufficient. When the car is driving at a high speed (the speed exceeds 120km/h/h), the tire pressure is insufficient, which easily causes the "resonance" of the carcass, resulting in a huge resonance force. If the tire is not strong enough or has been "injured", it will explode. Moreover, insufficient air pressure makes the tire sink more, and it is easy to cause the tire wall to land when turning sharply, and the tire wall is the weakest part of the tire, and the tire wall landing will also lead to a puncture.

4, it is the tire "working with illness". After a long period of use, the tire is seriously worn, the tire crown has no pattern (or the pattern is too low), and the tire wall is thin, which becomes what people often say as "bare tire" or "uneven weak link" and will burst because it can't stand the high pressure and high temperature of high-speed driving.
