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.
On my passenger car I always make my tire pressures about 5-7psi more than the label. It gets way better MPG and have driven this way for 3 decades with millions of miles.... On an RV I go right off the mfg suggestion to the max or tire max. One of the other. RV's are simply too heavy and large to mess around with. (Especially on my class A bounder. My little Toyota class c I've played with some on psi with no problems)
