Why do new tires have to replace the valve?

A new valve must be replaced when a new tire is replaced. This is because the valve is a rubber product, and there is an aging cycle problem. Since the valve is an inevitable aging problem of rubber material, the valve body will gradually crack, deform and lose elasticity. When a new tire is replaced, although there is no problem with the valve at that time, the valve may age in advance during the service cycle of the new tire, causing a safety hazard. The valve replacement cycle is generally 3-5 years.

Of course, there are also metal valves on the market: 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. Due to the change in material, the price of steel valve is much higher than that of rubber valve, and the service life of steel valve is two to three times that of rubber valve, which is mainly due to the fact that its metal material is not easy to be oxidized, and at the same time Metal valves also have better air tightness. Metal valve is really good, but the price is much higher than the rubber valve.
