So when I put my tires on in the fall, all 4 stems were frozen, and I don't carry Vaseline or any anti-seize for my schrader valve stem caps so don't even start with that.

Cost the boys at TireRack 4 TPMS, mount and dismount, plus my friendly face in their office for an hour!

BTW, who checks air pressure every month? Do you all have leaky valve stems? Tires hold air, then they go flat, why check them all the time? My BMW tires hold air, all the time, every day, it's weird, but I think tires are supposed to hold air.
This wasn't the point of the thread, nor was the 2 year time frame. What is the point, you already found out about, and my tire pressure may not change monthly, but how would I know if I didn't check. The TPMS will let it vary (2-3 psi?) by more than I want.
