I recently put my wheel/snow package on - bought from Tire Rack with the TPMS. This is the second package I've bought from them with TPMS (the other was track tires for my other car). I've swapped the wheels on the other car numerous times since last spring, and have about 30 miles on the Z with the snows. The TPMS light has never triggered on either vehicle. I wonder why others are getting different results.
