How frequently does the TPMS sample tire pressures?
I have personal experience with not noticing a deflated right rear tire (down to about 15 psi) in a Civic hatchback. With little weight on the rear tires, the tire did not appear to be low, and things felt OK until I pushed the car hard into a left hand sweeper in an on-ramp. One deflated tire really changes your diagonal corner weights!
Art - Per the FSM CD's 2012 and 2015 Mustangs update every 60 seconds. These cars, as you know, use sensors in each wheel. The 2015 Mustang displays individual wheel tire pressures. The displayed values are within about 1 lb of what my gauge indicates.
The ones in the Camaro are quite accurate as well, it would be quicker and easier for me to buy a nice dial gauge though with a pressure relief to adjust pressures. I've been slacking though and haven't picked one up lol.
