Problem with bumping the pressure is the tires will wear in the middle and fail inspection sooner but will have plenty of tread on the tire shoulder.
Tires will need to be replaced sooner.
I was running 50psi in my suburbans rear tires for some trailer towing, forgot that they were aired up to 50psi and ran them that way for a few months. Now the back tires have about 3/32'' less tread down the middle and the shoulders on the rear tires are all but untouched.
The fronts have always had 38psi and appear to be wearing very evenly accrost the tread.
