Your front axle has a lower weight rating, If you run max pressure in the front it will likely start wearing the center of the tires, and ride rougher. I would guess the rears are worn more in the center, due to the truck being unloaded most of the time.
If I do a long trip in the truck unloaded, (which is rare) , I drop the pressure to 60 psi in all 4 tires. I run 70 psi cold in the front, and 80 psi cold in the rear when loaded. Note that if you have a tire pressure monitor, or check them after driving, the pressure will rise several psi. I have seen over 100psi on both the trailer and the truck on a hot day after towing for over an hour.
