Max Tire Pressure.
Don't let the "Max tire pressure" scare you. After driving for a while, its going up as much as 15% along with the temp. This is NORMAL! If you check the pres AFTER driving, you have no way to judge what was your "COLD" inflation pressure was. You have to wait at least 3 hrs for the temps and pressures to go back to "cold".
I see 90-91 psi while driving on hwys in the southern states where they are much warmer than up north. You won't know this unless you have a TPMS, which are worth their weight in gold. RV dealers should include them with every unit. They can save you BIG PROBLEMS! Most tire failures occure at or above 175* per the TPMS people.
I ride on LRE tires which state 80psi cold and that is where I run them.
