The correct tire pressure is the pressure that gives you the best ride while going down the road. You will have to experiment with tire pressures (every time that you go out) to find what works best for you. I own a Winnebago and the manuals (Winnebago & Michelin) said 75 lbs. psi rear and 90 lbs. psi front. That didn't work for me it caused my coach to have tire squirm (wishy, washy, side to side feeling) I experimented with tire pressure and found 100 lbs. psi all around (all 6 tires) gave me the best ride! I got a good ride and my tires lasted 10 years at that tire pressure. Also be aware the lower the tire pressure (psi) that you run inside your tires the more heat builds up inside your tire! High heat is a enemy to tire wear and tire failure. Not trying to scare you just inform you to help you make a correct decision. I'm not a tire expert but I'm a retired over the road trucker 44-1/4 years driving and have owned a RV since 1976 so I know a little bit about tires, I've been around them most of my adult life. Great Question
