There are basically two ways to establish your cold inflation tire pressures.
1. Your gross axle weight rating (GAWR) for both your steer and your drive axles. Those ratings should be on a placard close to the drivers seat. Adjust your tire pressures to carry this max weight. Tire manufacturers publish charts with the proper pressure. Remember these pressures are the minimum required to support that weight. It's ok to go higher but never lower.
2. Weigh your coach. The best is a 4 corner weight but a weight by axle is easier to come by. In the case of 4 corners, inflate to carry the weight of the heaviest end of the axle. Never mix pressures on the same axle. If you get an axle weight then you don't know if one end is heavier, so plus up the pressure by 5 psi or so to cover any imbalance.
