I run 22-25psi in 40"s (load range C) on the street. I initially ran 28-30psi when I first got them and it was a horribly rough ride. Took them down below 25psi and it made a huge difference. No problems with the tires feeling too soft or squishy in turns, sidewalls look about like you want them for the street, and the contact patch after a quick chalk test is just about perfect for even wear at all four corners. My 4 door is fairly heavy too with the ProRock 60's. I would not think that 22psi is too low, especially on load range E tires
Load range E minimum pressure: 35 psi
Passenger (p metric tires ) 26 PSI minimum
Metric tires 22 psi minimum
