My '07 has the TPMS and I am about to change from my stock 20" wheels to a aftermarket 18" wheel. Does anyone know if the factory sensors from the 20" wheels will swap over to the 18's or do I have to buy new sensors?

 

Sensors and cradles are fine, you just need to get new straps to mount the cradle/sensor.

 

A tire place told me the other day they can get new straps for $12 a piece. Someone here suggested going to Fastenal and see if they had a hose clamp that big. I was wondering if you could use those plastic ties if they made them that big. Might be even cheaper, but I don't know about whether they could take the heat.
