I run my E rated/10 ply 35x12.5R17 at 48 psi front and 38 psi rear. It rides tons better than when the tire shop installed them and had them pumped up to the maximum 65 psi. As mentioned above I keep an eye on how much the psi increases on the freeway. On a normal drive of about 10-11 miles on the freeway they only go up about 3-4 psi, and I've driven in a couple hundred miles in one shot and the same thing.
Just bought the truck this winter and then with the C-word this summer haven't but in a situation that I needed the tires aired down for off-roading. My plan was to start with going down to about 30 on the front and 20-25 rear (also keeping in mind that it wouldn't be true hardcore off-roading). On my K5 trail rig I do down to around 10 psi on the 40" tires.
