Yes; up to 80 cold; but the best situation is to know your RV's corner weights and adjust the air pressure according to the tire manufacturers rec-commendations on their web site.

i agree find weight. also the more air the harder the ride. it's your a motor home not a semi...you pick it's your house.

I would imagine your motor home when new, came with D load rating tires which had a maximum of 65 psi. Your current tires are more than likely have an E load rating with a maximum of 80 psi.

More than likely 60 in the front and 65 in the rear is still the way to go. Weigh your motor and adjust your tire pressure to the weights in the following link Michelin Americas Truck Tire Load & Inflation Tables and maybe add 5 psi or so for a cushion.

Many years ago I had a 22' Class C that came with D tires, which were eventually replaced with Es. The ride got so much rougher with the Es.
