You will have to determine what you want to do in this regard.
I agree , One of the little known recommendations by the tire manufacturers is to increase the tire pressure to the lower of the max rating of the rim or tire when placing into long term storage. ie MH Manufacturer max rating 90, tire rating 120, Rim max 110. Inflate tires to 110 for storage reduce to 90 or lower based on actual axle weights when bringing out of storage.
This assists the steel belts.
Here is good link

The rating by the MH builder is the max pressure for the coach under maximum load per axle ie 100 front 90 rear(duals) Over inflating can be hard on the suspension.
