How Often Should Car Valve Stems Be Replaced?

[Camila]

Car valve stems should be replaced every three to five years. The valve stem is a crucial component for maintaining the air pressure in tires, primarily used for inflating and deflating tires while ensuring airtight sealing after inflation. Since valve stems are made of rubber, they are prone to cracking, deformation, and loss of elasticity. If you only replace the tires and neglect the replacement cycle of the valve stems, the stems may age prematurely, increasing driving hazards. Before inflating the tires, use an air gun to clean the dust around the valve stem and core to prevent dust from entering the inner tube. Additionally, the valve cap is very important as it isolates the air, preventing damage to the valve core's sealing rubber from dust, water, oil, etc., thereby extending the service life of the valve core.
