I have noticed the the TPMS reads the tire pressure about 4 psi high. In other words, when my tire pressure gauge reads 32 psi, the tpms reads 36-37 psi. Is that normal for the TPMS to be that far off? I was also wondering what pressure you guys generally keep your tires at for everyday driving. Do you keep them at 32 front and 34 rear like the sticker on the car says, or do you keep them higher or lower?
