Do OEM Valve Stems Need to Be Replaced?

[NaomiFitz]

When replacing new tires, it is necessary to install new valve stems. This is because valve stems are rubber components and are subject to aging cycles. Although the valve stems may appear intact at the time of tire replacement, they could prematurely deteriorate during the lifespan of the new tires, posing safety risks. Relevant information about tire valve stems: 1. Function: Tire valve stems are one-way valves (check valves) used for inflating or deflating tires with gas or liquid while maintaining and monitoring internal pressure. For tube-type tires, they are mounted on the inner tube; for tubeless tires, they are installed on the wheel rim. 2. Types: Based on structure, they can be categorized into rubber-metal valve stems and metal valve stems with rubber gaskets. The former is used for passenger car tire inner tubes, while the latter is primarily for truck tire inner tubes. The internal structure of tubeless tire valve stems is identical to standard valve stems.
