My 12 Ram 2500 CTD LB CC 4x4 door sticker says 65 front and 45 rear when not towing. That's for 245/70/17 OEM tires. I can't see 265s being much different.
Towing says 75 front and 80 rear. I never run 80 in the rear. The front and rear weigh almost exactly the same when loaded with my 5th wheel. Rear is 48-4900lbs and the front never changes at 4800lbs. So if 75 is good for 4800 then it should be fine for 48-4900lbs. My tires all wear fine running those psi's.
Remember the rear is around 27-2900lbs empty so you don't need 65psi in the rear like the front that weighs 4800lbs.
