tire pressure
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.

Over inflation will give you a very harsh ride and also cause irregular tire wear patterns.
That is exactly why you don't over inflate. Doing the TPMS experimentation will get you right where you should be at each corner of the coach.
The max pressure may not be the tire's, it may be the rim"s. our tire max pressure matches the rim's 120 PSI.
using the TPMS, we found that 90 PSI will allow the tire to heat to 115 psi, increasing the pressure to 95 the tire will heat to about 110psi. 97 psi the tire will only heat to 105. ride is good and there is no wear problems.
