When I got my Sport 2 door (Bridgestone ATs) in July, I set the cold tire pressure at 35. Temps have dropped and cold pressures went down to about 30 according to the tpms. Of course it told me I was low on all four. Today I aired all four up to 36 cold. Tpms now says one is at 41and the other three are at 30. What the hey? This is just sitting in the driveway. Do I just have to run it on the road awhile to clear it, or is it glitching?
