As TWest says, you may have to compromise a little. I do tire pressure adjustments to keep a decent ride when empty as I would never run any tire that was not Load Range "E" on these trucks. I however do not have a dually as you do so rear pressure adjustments will be more of a PITA. I drop the front down to 65-70lbs and the rears down to 55-60lbs when commuting empty. Increase to 75-80lbs front and rear when towing depending on how much firewood and grandkid stuff that the wife has loaded in. That has been the formula I have used on all 3 Cummins powered trucks that I have owned over the years and seems to work well. I may try the Pirelli's that SteveD is running next time, I just checked the tread design and specs, looks pretty good.
