My door sticker says: Front - 70 psi, Rear - 65 psi. Been towing a 19,000 pound TH with those pressures for 3.5 years now with excellent tire wear and no tire failure issues. I run Michelin truck tires on my TH and never run max pressure. I keep it at 70 psi. Michelin charts say psi should be 65 psi as each tire is never over 2600 pounds loaded. Again, good tire wear and no tire failures in 3.5 years.
BTW, the tire failures were all Firestone tire related and the tires were bad, not the sticker on the door. Firestone recalled 28 million tires and closed the plant that made them. Also, the owner's manuals dictated proper inflation pressures for carrying loads (if they were ever read).
My 07 Dodge 3500 DRW gives the same pressure of 65psi for max load for rear tires this is for a 235/80/17 E, hope this helps.
