Is it just me or is the service tech full of it? Are these sensors under warranty?
(OK for all you guys north of the Red River – This is North Texas - we don’t deal well with temperatures below 40°F / four seasons here, Fall – Early Summer – Summer & Late Summer)
The techs are full of it. When I used to have the "cold weather" TPMS, I'd reinflate the low tire, and the guage changes immediately. I've heard that the TPMS comes on when a tire dips below 4PSI below the other tires. Reason would conclude that if all tires experienced the same temp. drop, the light shouldn't come on. Can anyone verify this?
