I was at the local park waiting for my son during his tennis lesson. After opening up the four vanity covers I decided to take a look at how the tires are wearing. They are wearing quicker in the center of the tread. The tires were just recently rotated, and the rear look worse than the front. Most of the time car is not fully loaded. It's my wife's primary car to go to work, and she goes twice a week nowadays, driving alone (single occupancy).
I'm guessing to try 32 PSI cold until it needs new tires and then maybe run 33 PSI? What do you think? (Thanks in advance).
