Tire pressure

[Cousey]

I have looked inside the door of my 2014 Ford class c Thor Chateau and tried to figure out the correct air pressure of tires front and dual back. It is very confusing. What air pressure would y’all recommend please? Also how do your access inner tires? Thanks

It is best to run across a scale to get loaded axle weight. The refer to the mfg tire pressure table.

The less optimal choice is tire pressure max on the sidewall. This will keep you safe but will not be best tire performance.

Here is an example of a manufacturer tire pressure table.

The door sticker and the Owner Manual should give the proper tire inflation pressure for the vehicle. This is for the vehicle loaded to the maximum cargo weight. This is always below the maximum inflation pressure stated on the side of the tires.
Thus, I find no reason to use any other tire pressure. Increasing tire pressure does not increase the maximum cargo weight for the vehicle. There are two pressure specifications, vehicle, and tire. The vehicle spec is always less and supersedes the tire specification.
