When I look at the tire pressure display, all 4 tires are around 45psi. But when I look at the label in the driver’s side door sill, it says 36psi. Should I keep them at the higher pressure or do I need to let some air out?

45 is right on the upper limit of the tires. 36 is the recommended for good ride and good mpg's.
I run 40, still a fair ride and a little better mpg's.

Tires mine came with say 44psi max. I have them in the high 30s. BTW the system started notifying me when the pressure dropped below 30psi.

My tires were actually showing 47 psi when I first got it. Was the dealer supposed to reduce them to the proper pressure during their “prep” of the car? Over 10 lbs pressure seems a bit excessive.
