I run what's on the side of the tire taking into account whether it's single or dual. My F550 (19.5) is 100 psi and Freightliner M2 (22.5) is 110 psi. These numbers are off of the top of my head, but I think that's whats stamped on the tires. Max pressure is fine as long as your rims and valve stems are rated to take it. High pressure sacrifices ride, but reduces heat. Worth the trade off in my opinion.
