What is the reason why automobile tires often leak air?

New tires have been installed, and all four tires are leaking. There are the following points:

1. The tire side and inner edge are damaged. Tire side damage: some car owners have poor sense of position. When parking, they often let the sidewall rub against the curb, which will wear the sidewall over time. Damage to the inner edge of the tire: The damage to the inner edge of the tire is mostly caused by operational errors when disassembling and assembling the tire, which generally occurs in the process of replacing the tire with a new one or installing the tire after repairing the tire.

Damage to the side and inner edge of the tire will cause hidden air leakage of the tire, which will have a high risk of puncture.

Inspection method: The tire side damage can be directly observed, and cracking and bulging will occur in severe cases. As long as this happens, it is necessary to replace the tires as soon as possible to avoid the occurrence of puncture accidents.

2. If the inner edge of the tire is damaged, the tire needs to be disassembled for inspection. Therefore, car owners should carefully supervise when disassembling tires in the repair shop. Foreign bodies are stuck in tires, which is the most common damage of tires. Foreign objects that easily pierce the tire include nails, screws, iron wires, glass fragments, sharp stones, etc. Among these foreign objects, nails and screws are the most likely to puncture the tire, causing the tire to leak.

Inspection method: There are foreign objects stuck on the tire. We can see them by carefully observing the tire surface. If the place where the foreign body is stuck is hidden, we can also sprinkle soapy water on the tire surface to find the place where the bubbles come out.

3. The wheel hub is broken. It is rare that the wheel hub is broken. When the wheel hub breaks, the gas inside the vacuum tire will leak from the cracks, and the tiny cracks will also become the hidden danger of the wheel hub breaking. It can be said that although this situation is rare, it is extremely dangerous.

Inspection method: it is necessary to remove the wheel during inspection, and then observe whether there are cracks on the surface and inner wall of the hub. If the hub has cracks, it should be replaced in time.
