I bought my new TPMS right from Discount Tire, they were cheaper from there & i have had no issues
The TPMS for the 2008 & later Rams all come from the same manufacturer
they are all called Schrader
i believe that they are
(433MHz) Dodge Ram 1500/2500/3500.
- Fits most stock and aftermarket wheels
this is what i found, check it with your tire company
