Is it necessary to change the valve every time a tire is changed

According to the actual situation of the selected valve, whether to replace it at the time of tire change.

Rubber valve: As the valve is an inevitable aging problem of rubber material, the valve body will gradually crack, deform and lose its elasticity. When the vehicle is running, the rubber valve will also deform due to the centrifugal force swinging back and forth, which will further promote the aging of the rubber. Generally speaking, the life of the rubber valve is 3-4 years, which is similar to the life of the tire. Therefore, the rubber valve is replaced when the tire is replaced.

Metal valve: In order to avoid the aging problem of rubber valve, metal valve gradually appeared on the market, and steel valve is one of them. Due to the change in material, the price of steel valves is much higher than that of rubber valves. The service life of steel valves is two to three times that of rubber valves. This is mainly due to the fact that the metal material is not easy to be oxidized. The metal valve also has better air tightness. Of course, the price of metal valves is much higher than that of rubber valves.

In addition, the metal valve of current affairs, sometimes due to impact, corrosion, etc., causes abnormal aging or deformation, it is also necessary to follow the valve. Therefore, it is also necessary to check the valve when maintaining cars and tires.
