Is There a Correct Valve Stem Length For Installing TPMS System


What length of valve stem should the tire have to install these? Our new rigs tires have about 3/4inch of the valve stem exposed.


Expert Reply:

The 3/4" of valve stem that's exposed for your setup will be adequate to accommodate the flow through sensors found on the TST TPMS for RVs # TST-507-FT-6-C or the cap sensors found in the kit # TST-507-RV-S4.

The manufacturer, TST, recommends installing their system on a metal valve stem like the part # AM20906 which measures 1-1/4" for what's exposed but aside from that they don't really have any guidelines on valve stem length. Really just as long as all of the threads for the valve stem are exposed is the main thing.

Attached are some videos for you to check out.
