From what I read, the "premium" TPMS uses a different wireless control module (also for the keyless remote), and transponders at 3 of the 4 corners to tell where each sensor is at. The Commander might have 4 transponders because of our system aslo monitoring the spare. I've tried a couple of times to talk to my local dealership, but they kind of suck. The sensors, as far as I know, are the same.
