285/75-16 ko2 psi suggestions

With my Duratracs, the previous owner ran them at 31psi for 2 years. They had already been worn funny by the time I got the rig. They are outrageously noisy. My new ko2's arrive tomorrow and want to make these last an acceptable time.

I ran the duratracs @ 41psi on 8" wheels with medium OME lift. I don't really weigh down much when we hit the trails or head to Colorado, Stock bumpers. I had the previous gen BFG AT's on our Excursion. Ran those @ 39front 42 rear(no rear sway). Does 41psi sound about right to start out with?
