Measure your wheel's valve stem hole before ordering; this stem covers both common sizes, 0.453" and 0.625". The easiest time to swap stems is while the tire is off the wheel, and any tire shop can fit them in minutes during a tire change. After installation, air up and check around the base of the stem with soapy water to confirm a clean seal.
Common questions
What does 1.25" effective length mean?
Effective length is the usable portion of the stem that sits outside the wheel. At 1.25" you get a standard working length that stays easy to reach with an air chuck or pressure gauge without sticking out further than it needs to.
Why choose a high pressure valve stem?
This stem is rated to 100 PSI max, which gives you headroom over everyday passenger car pressures. If your setup calls for higher inflation pressures, a high pressure stem is the appropriate match.
