Okay, got a set of wheels off a RAM 1500 for my winter tires. They fit perfectly, but the TPMS sensors won't talk to the car. Apparently there are a lot of different part numbers out there every one saying theirs "fit". Can anyone steer met the right numbers?

 

The sensors need to be programmed to the BCM of your vehicle for them to "talk" to each other. The ones in the rims you got are programmed to the vehicle they came off from. Should be able to have any decent tire store program them for you to your vehicle.

 

The rims came with the wrong (newer) frequency for the car year. I got some replacements (315 mz).
