Should the valve stem be replaced when changing tires?
1 Answers
When changing tires, the valve stem should be replaced as well. Rubber valve stems: Rubber valve stems typically have a service life of about two years. During use, the rubber undergoes aging, leading to gradual cracking, deformation, and loss of elasticity in the valve stem body. Additionally, while driving, the rubber valve stem may sway back and forth due to centrifugal force, causing deformation and further accelerating the aging process of the rubber. Metal valve stems: Metal valve stems effectively address the aging issues associated with rubber valve stems and can extend the service life by two to three times. The most common type is the steel valve stem. Besides being resistant to oxidation, metal valve stems also offer significant improvements in airtightness.
