I got my new (to me) 2015 model S a few months ago. Recently I noticed that one of the tires was a little low according to the pressure readings on the screen. Today I went to fill the tire and discovered that the tire was actually very low and, in fact, the other three tires were all a bit low. It seems that the sensors are reading about 10PSI too high on all four tires. Is it possible for me or the SC to calibrate these?
