I found 55 psi in LT265/70-17 E tires on my 2500 Dodge/Cummins works best when towing or not towing with my GN trailers and a 11200 lb 5th wheel trailer
And 70 psi in the rears for a 5200-5400 lb axle load.
When empty I drop the rears to 45 psi as each tire is only carrying around 1400-1500 lbs.
Pretty much the same as JIMLIN for my 3500 CTD (same tire sizes).
I simply use 50 for all four when not towing, or with no load, and increase the rears to 70 or max as indicated on the sidewall (80) when towing or hauling a load.
