This chalk line ended up a bit crooked, but after a few trips back and forth, with air being added at 5 psi per trip, this tire was the first to show even wear from one side to the other when it reached 30 psi. The other tires were brought up to this amount of pressure and all showed evenly worn chalk lines during the next couple of passes in the parking lot. When the truck’s new optimal tire pressure was applied at all four corners, the ride and handling felt excellent when it was taken out on the streets for a test drive.
