Tire pressure

I'm new to motor homes. The sticker on my newer class c door calls for 75 psi in front tires and 65 psi for back duallies. Max psi stamped on all of the tires is 80. Advice?

What is on the tires is the MAXIMUM safe tire pressure for the tire, cold, regardless of the vehicle the tires are installed on. Thor has used the max axle weights of your coach and matched the minimum tire pressures to carry the max axle loads, and thus give you the best ride and tire life. If you travel light, you can weigh the coach and safely reduce the tire pressure some. My coach sticker says 82 psi all around. Weighing my coach, fully loaded, I run 76 psi in the front and 82 in the rear. You wouldn't think that 6 psi would matter but it makes for a significantly softer ride.
