Why?If the Wrangler the wheels were taken from was built after 6/5/21, the sensors are incompatible with a JT built prior to that date.
I'm not sure exactly what changed, although I suspect it is something in the communications protocol. I've been trying to find the new sensors for the wheels I ordered, and the sensors are backordered everywhere. Here's a link to further discussion;Why?

If it was that old. There is a decent chance that they won't work at all with your truck. The only way to know for sure would be to look at the make and model of the TPMS sensor.the wheels are aftermarket (motometal)
they where paired to a 2012 jl
