So, my GTS has 21-inch wheels with summer tires from the factory, which is correctly selected in the car’s TPMS settings. This makes the car and app show a desired (cold) pressure of 36psi front, 38 rear based on the deviations shown on screen. My door plate differs though, showing 41 front, 45 rear. Is the door plate assuming different tires? Should I just trust the PCM/app deviation values?
