2005 Winnebago Adventurer w/ Michelin 235/80 R22.5 tires. What tire pressure is recommended for a fully loaded motorhome? I have had several "suggestions" from RV repair facilities.
Crank it up to the maximum on the sidewall and go down the road happy. If the tire should lose a few pounds during a long trip don't sweat it. I start at 80 psi and will let it go down to 75 psi before adding air.
