I assume you up sized in load range. Weigh your rig. Use load/inflation chart for your tire and add 5psi. This is per GY Tech Support.
Help me out on this. My camper weighs in the neighborhood of 9700 pounds when loaded, give or take a few hundred pounds. It depends on what we're bringing with us on any particular trip. The stamped maximum load capacity on the rims is 2830 pounds, the same as what is on the Goodyear Endurance ST 225/75R15 E rated tires. From what I can tell on the chart, it says 80 PSI. Are you saying to air them up to 85 PSI Cold?
Did you go from "D" rated tires to "E" rated tires?
What your RV weighs has NOTHING to do with the weight that's on the tires. Tongue weight and pin weight play a part.
