How to judge the life of the tire valve?

Generally speaking, the service life of the tire valve is 3-4 years, which is almost the same as the service life of the tire. Therefore, it is recommended to replace the rubber valve when the tire is replaced. If the rubber valve turns dark red, or fades when touched by hand, it means that the valve has been seriously aged and cannot seal the tire, and if it continues to be used, it is easy to cause air leakage or tire blowout, and it should be replaced in time.
