Best to weigh your coach, then go to your tire manufacturers web site and inflate your tires to the recommended pressure shown on their load inflation chart that safely supports the weight of your coach.
Best of luck and safe travels.....

Without knowing the weight of the coach, the safest pressure is the max allowed for the tire.

Best is to corner weigh your coach if possible and inflate the tires on each axle for the highest weight on the axle.
There should be a tire size and pressure placard somewhere in your coach. This is the manufacturers estimate of the tire pressure for your coach when it is loaded to the maximum recommended weight of the coach.
The max pressure will be fine but may give you a harsher ride than you need if you are not near the capacity of the tires.

there is a tech sheet affixed to somewhere in your coach. some on the wall below the window at driver side, some on back of a cabinet door in bathroom... the tech sheet will have the recommended tire pressures for your specific coach. if you don't want to do a 4 corner weigh, this is probably the closest numbers you can get.

x2 what CountryFit said. Per federal law, there is an RV manufacturers recommended tire psi (front and rear) posted in the coach near the driver seat, so use it. Don't deviate from that unless and until you get the coach weighed (axle by axle or wheel by wheel) and can look up accurate pressures in the tire makers inflation tables.
You cannot use somebody else's "good" tire pressure. It's far to dangerous to even consider that.

Keep in mind tire load/inflation charts show the minimum acceptable pressure for the corresponding load. Use the RV placard tire pressure. You'll get better tire wear, crisper handling, and be confident you are not overloading your tires, which is the primary reason for tire failures.

I have over 30 posts on proper tire inflation on my blog.
