Assuming you have the 6.7L diesel in that truck, the fronts are almost untouchable for tire pressure.
I previously owned the 2011 model of your truck, with same sized tires (LT245/75R17's) and was running fronts at 55 PSI, as that is where they were at when I bought the truck new. Well, after bad wear, cupping, and sometimes death wobble problems, I upped the fronts to the 75 PSI area and viola! All the problems went away.
So, as I said, fronts equal untouchable. That diesel engine is HEAVY!
Rears, drop them down to where you feel comfortable. 50 PSI would not be a problem there in an unloaded situation.
