Fitment and specs
- Industry number: TR501 truck valve stem
- Material: brass
- Fits oval valve stem holes measuring 0.64" x 0.85"
- Effective length: 1.5"
Valve stems install with the tire deflated and the bead broken so the base can seat squarely in the rim hole. Once the tire is mounted and aired back up, brush soapy water around the base and the core and watch for bubbles to confirm the seal. Fitting fresh stems whenever new tires go on is cheap insurance against slow leaks.
Common questions
How do I know the TR501 fits my wheel?
Check the valve hole in your rim. The TR501 is made for an oval hole measuring 0.64" x 0.85", so a wheel drilled with a standard round valve hole needs a different stem.
What does effective length mean?
It is the usable length of the stem measured from the rim hole to the valve tip. At 1.5" the TR501 keeps a short profile that stays out of the way.
