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?
GMandJMExplorerSep 17, 2015We've used TST sensors on rubber valve stems and had no issue. Others have said there sensors wouldn't work. Give it a try and see. If it doesn't work, consider metal stems.
