GEN 1 Is there a way to look at the valve stem and tell if its a TPMS ? ---

I bought a set of OEM Bead-Lock wheels from someone with the stock tires mounted on them ... from a 2014 truck.

The guy didnt know if they still had the TPMS sensors still installed or not ... and I would bet they are still in there if the stock tires are still on, but there is a chance someone yanked them out I guess.

Is there a way to look at the stems and tell if they are the TPMS stems?

Also, whats the procedure to re-train the "new" TPMS sensors to my 2011 truck if they happen to still be installed on the 2014 wheels? I was thinking a super strong magnet at the stem tip?

Thanks! ---

Pull the valves (small tool required). Look inside and you'll either see the inside of a monitor or the inside of the wheel.

I switched my wheels from another truck and my truck "learned" the new ones......

Awesome, I can definitely do that ... thank you very much Ruby! ---
