TPMS for 2013 Ford E-450
1) Has Ford ever offered a TPMS (with internal sensors) as a factory option for the E-450? If so, 2) Is it possible to find a truck tire shop that will retrofit the TPMS? 3) Another possible solution is a product like the Tire-SafeGuard TPM-C106N Kit. It calls for flow-through sensors to be mounted on metal valve stems. Is this generally regarded as an absolute requirement? If yes, 4) Do (straight) metal valve stems come in a variety of lengths? (I would need 2 or 3 different lengths if leak-prone extensions are to be avoided). 5) Is the mounting hole diameter for metal valve stems fully standardized for all types of wheels? (I have the "alloy" option). 6) Can the use of Loctite (blue) improve the odds that valve stem extensions won't leak?
Thanks a lot.
