Typically made from rubber or metal, valve stems are threaded onto the wheel and contain a spring-loaded valve core that controls the flow of air in and out of the tire. Valve stems are essential for maintaining proper tire pressure, which helps ensure optimal handling, performance, and safety while driving. They also allow for the convenient and efficient filling of tires with air, as well as the release of air when necessary for adjustments or repairs.Copyright (C) 2023 Initial Holdings LLC dba Center Cap Authority.
