Dually tow vehicle tire pressure
Ok. Dually Truck door jamp sticker says rear pressure 65 pounds and front 70. My 5th wheel is 12995 dry and 15000 loaded. I run 80 pounds in rear tires when towing which is maximum rating. I run 70 in...

So the newer GM duallies have LT235/80R17E tires, which at 65 psi are rated to 2680 each. The front GAWR appears to be 5600 pounds. So at 65 pounds inflation the tires are unrated for the max axle rating. So are you sure it says 65 pounds all the way around.
BTW at 35 pounds dual the tire is rated at 1570 each or a total of 6280, which is fine for casual everyday used include runs to box stores giving well over a ton of capacity in the bed.
