TPMS valves

is it manditory to replace tpms valves in vehicles equipped w/tpms, or can a regular old style valve stem be used . we have snow tires and wheels without tpms valves in them, our new veh has tpms valves . light is on , someone told us its against the law to NOT have tpms valves on a car equipped with tpms. we are driving around with light on ???

It is not illegal to drive with no sensors in your tires. The law only requires that all new vehicles sold in the US come equipped with them. Ignore the light on your insrument cluster through the winter.

Mark your wheels when you remove them RF,LF,RR,LR so you won't have to re-program your sensors when you put your summer wheels back on.

there's very likely TPMS fuse somewhere, you know...

Depending on the state you live in, and I do not know of any at this time, it probably would not be illegal to run without the TPSM's. BUT--most manufacturers now have built into their computer system a warning for low tire pressure that cannot worked around. As far as I know, and I don't know all, there is no fuse for any of the TPSM products. Learn to live the the "Low Tire Pressure" light on. Some of the newer cars even have the chimes set to go off at intervals to remind you.
