I have the 305 55 20 and I run 40psi all around. Max on mine is 65psi.
More than 40 and the ride gets pretty harsh. Might air up a bit when towing.

Update, just went up to 50psi and that seems to work a lot better for handling and mpg! And the ride didn't change much at all. When I first got the tires I tried 45psi and the truck was very rough so I went with 40psi and that seemed to help. So I am assuming the sidewalls have softened up a bit and 50psi works great now. Hope this helps.
