The car suddenly had a flat tire.

It should be that when the side of the tire rubbed against something, the stolen goods were squeezed between the tire and the hub, causing the tire to leak.

1, tire nailing, usually in the plane position where the tire touches the ground. You can see nails or other foreign objects when you turn the tire. Pull out nails or foreign objects and repair them with tire patching glue.

2. If it is confirmed that there is no puncture, it is likely that the valve core is damaged (the valve is leaking). If you are wearing washing powder or detergent, you can try the air leakage position. If it leaks, please replace it.

3. At the contact position between the tire and the rim, air leakage is caused by oxidation, rust or foreign matter on the rim. This kind of air leakage is generally slow, and sometimes the tire pressure is not enough in January. Remove the tire, clean the contact position between the rim and the tire, and reinstall the inflation.

4. The seal between the tire and the steel ring is not good and there is air leakage. Nowadays, almost all automobile tires are tubeless tires, which need to be closely attached to the rim to achieve sealing and ensure that the tire pressure does not leak.

Extended data:

1, tire, is the floorboard of the tire, usually made of wear rubber material, there are solid tires and pneumatic tires, pneumatic tires are composed of inner tube and outer tire. General manufacturers set the service life of tires as 3 years. If the vehicle travels 20 thousand kilometers a year, it can be replaced in 2~3 years.

2. The service life of the tire is set by the manufacturer as 3 years. If the vehicle travels 20 thousand kilometers a year, it can be replaced in 2~3 years. If you run about 65,438+00,000 kilometers a year, you should replace it in 4-5 years. If you only drive 5000 kilometers a year, it will take four to five years to consider replacing it.

3. Even brand-new tires should be considered for replacement after 3 years. Therefore, the spare tire in the trunk of the car also needs regular maintenance, and the spare tire that has not been used for too long needs to be updated.

4. Generally, the car should check the tire pressure at least once a month, and pay attention to adjusting the tire pressure every quarter. The ideal adjustment time is 165438+ 10 and May, and 165438+ 10 basically enters winter, so the tire pressure will usually decrease, so it should be adjusted slightly.

In May and May, the weather began to get hot. It is recommended to check whether the air pressure is normal. At this time, we should pay special attention to it. As long as the tire pressure is not too much higher than the standard range, don't deliberately reduce the tire pressure. If the tire is not flat, there is no need to adjust it every month.
