Colo_NativeExplorerSep 17, 2015TPMSI ordered my TST 507 TPMS and it said something about replacing the valve stems with metal ones is it really necessary?
SanMarMorExplorerSep 17, 2015Absolutely required. I had stems with a metal tube, but a rubber base. I thought that would work. But the forces of that sensor spinning around, finally broke the stem off at the rubber base. Luckily I didn't lose the sensor.Do yourself a favor, get the metal stems.
