How often to replace tire valve

The service life of the rubber valve is 3-4 years, which is similar to the service life of the tire. Therefore, it is recommended to replace the rubber valve when replacing the tire.

The types of tire valves are as follows:

1. Rubber valve. As the valve with the most common material, the low cost makes the rubber valve widely assembled on the original wheel rim, and the replacement cost is also very low in the future. Due to the inevitable aging problem of the rubber material, the valve will gradually crack and deform. , lose elasticity. When the vehicle is running, the rubber valve will also be deformed by swinging back and forth with centrifugal force, which will further promote the aging of the rubber.

2. Steel valve. In order to avoid the aging problem of rubber valves, metal valves have gradually appeared on the market, and steel valves are one of them. The service life of the steel valve is two to three times that of the rubber valve, which is mainly due to the fact that the metal material is not easily oxidized, and the metal valve also has better air tightness.

3. Aluminum alloy valve. Aluminum alloy valve is also a metal valve, its service life and air tightness are comparable to steel valve, but the price has further increased, mainly because aluminum alloy is lighter than steel, which undoubtedly improves the dynamic balance of the wheel. favorable.
