I can tell you about my 2005 with the same tire size.

My truck has hauled RV's as a living since day one about 60-65% of the time. I average about 20,000 pounds gross combination weight. At first I started out with 65 psi all the way around when hauling and reduced the to 55 psi when empty (I have a compressor onboard). I watched the tire wear and all was good. Rotated every 20K miles. I got tired of the air change and left the pressure at 65 psi all the way around all the time. The last set of Michilens came off with about 3/32nds inch at 161,000 miles! My driving speeds are 58 mph loaded and 65 sometimes 70 empty. Loaded I am runing about 60-100 hp over stock and empty much more. I make sure I rarely spin my tires but I do use a heavy throttle quite a bit!

2007 Mega Cab Dually, Pull a 10,000 5th Wheel about an average of 30 days per year, runs empty 90% of the rest of the time. Run psi at 65 all the way around all the time. It dont run like no limo, but, hey, it is a truck after all

2005 Reg Cab Dually 4x4 towing 26' enclosed trailer with race car & gear & carrying 1000 lbs camper I run 70 lbs in all the tires.

Original Generals have 45,000 miles on them & the wear pattern is very even. They will need to be repalced due to dry rot long before I mile them out.
