The lowest cost of the rubber valve is widely assembled in the original wheel rim, and in future the replacement costing is very low.

The rubber material inevitably aging problems, the valve will gradually crack, deformation, loss of flexibility. And when the vehicle is running, the rubber valve will swing back and forth with the centrifugal force deformation, which will further promote the aging of rubber. In general, the rubber valve life of 3 to 4 years
Aluminum alloy tubeless valve is more cheaper than brass and zinc alloy material. The weight make it more better for tire balance.

So Zinc alloy valve is replaced by Aluminum alloy tire valve gradually. Price ,function make it more popular.
