2009 Chevrolet Malibu - 81PSI?

You have to clarify where that reading is coming from.
Is it from the vehicle’s TPMS?
Is it from a tire pressure gauge?

Is it possible that the tire is actually overinflated to that extent?
If the answer to my last question is “yes”, then you need to use a reliable tire pressure gauge to deflate the tire to the level specified on the door jamb label before driving it.
