About the tyre valves

Valve is used to charge and discharge the tire gas, and can maintain the tire pressure of the one-way valve.

Now the cars tires are tubeless tires,in the valve structure of the tire are separated from each other,the valve is mounted on the rim to play its role.

Though the tire valves is small,it consists of the valve body (base), liner, fastening nut, valve core, valve cap composition,and each part also has its own role

Different material of the valve

Rubber tire valves

As the most common valves of the material,the lower cost of the rubber valve is widely assembled in the original wheel rim,and the cost of replacement  is also very low in the future.

However,because the inevitable aging of rubber material,the valve body will gradually crack, deformation, loss of flexibility.

And when the vehicle is running,rubber valves will also swing back and forth with the centrifugal force deformation,this will be more prompted the aging of rubber.

In general, the rubber valve life is 3-4 years,and tire life is almost the same,

It is advisable to replace the rubber valve when you replace the tire.

Three kinds of material in the weight of the valve itself also has a significant difference

Steel valves

In order to avoid the aging of the rubber valve,the metal tire valves gradually appear in the market,the steel is one of the valves.

Because the material has changed,the metal tire valves price is higher than rubber tire valves.

Steel valve life is two to three times of the rubber valve,This is mainly due to the fact that the metal material is not easily oxidized, and the metal valve also has better airtightness.
