using the stickers or information on the coach is probably not applicable, it's showing 'max' pressures, not what you should be using for your actual weight, including your 'stuff' and people on board.
Goodyear and others have this info on their websites - use your front axle weight, and rear axle weights, to determine the front and rear tire pressures - more than likely they won't be the same, and will be much less than the 'max' printed on your stickers or tires themselves.
a CAT scale at any truck stop is an easy and cheap method to weigh your coach, about $8 maybe. Have 3/4 tank of fuel, 3/4 tank of water, and everyone that normally travels on-board so that you get a 'real world' weight for each axle.
I run 95 on fronts, and 90 on the rears. My coach also rides much smoother with the correct tire pressures.
