What psi do you all run in your little freightliners to maximize tire wear, ride and mpg?

This is Goodyears load/inflation table... Should be compatable with Michelin, Bridgestone, Toyo, Sunimoto, Cooper, and others....

Knowing what each axle weighs helps in deciding how much tire pressure to run.

What's my correct tire pressure?
Michelin has evaluated the SportChassis and made the following recommendations for safe operation on the road.
  • For 19.5" tires: 60 psi front and 50 psi rear
  • For 22.5" tires: 95 psi front and 95 psi rear

    Location: Ingalls, Ks    		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.
