Appropriate Tire Pressure?
I have a 25' Class B+ motorhome. It has 16", Load E tires rated at 80psi cold. Is it safe to run them anywhere between 65psi - 80psi cold? I currently have them inflated at 70 psi, we have an average...

Whatever the Chassis manufacturer (Ford? Chevy?) sticker in the door jamb says, is THE MAX. That is almost certainly less than the 80 PSI on the sidewall of a Load Range E tire.
Weighing your coach, as ready for travel (people, supplies, stuff all on board) at a truck stop or other scale is best. Than adjust pressure according to a Load/Pressure chart. Adjust again once the tires are cold. Michelin's chart is easy to find. You can use that chart for Michelin or other brands, as long as the specs of the tires are the same.
If you tow a car, have it behind you at the truck stop CAT scale. It'll give your Front Axle as "Steer", Rear Axle as "Drive" and Car as "Trailer."
