Tire pressure

[Mulletman]

I have a 2001 f250 3/4 ton 4x4 and I have 305/55/r20s nitto trail grapplers on it, and I was wondering what pressure to run in them without any load. I want the best pressure for longevity of the tires and ride quality so any suggestions would be appreciated!

What does the side wall say for max load? I normally run 15-20lbs less then that. Then bump em up for hauling

I run my 275/65/20 toyo open country at2 at 60psi unloaded

I believe the max psi is 65
