Never heard of an RV manufacturer dictating to customers what size tires "they should have"

Read your owner's manual, it's in there.

To funny, I have bought several new trailers through the years and NEVER received a owners manual. Just a collection of literature from the various manufacturer's of products used in the trailer. Maybe you can point out just where the manufacturer stated exclusively to use only the tire size that it came with. I could understand a manufacturer not wanting a lesser tire to meet maximum load capacity.

Vehicles are calibrated to use a certain size tire. Trailers clearance is usually the limiting factor along with cost to the manufacturer.

To maintain tire safety, purchase new tires that are the same size as the vehicle’s original tires or another size recommended by the manufacturer. Look at the Tire and Loading Information label, or the sidewall of the tire you are replacing to find this information.

That statement/similar statement is mandated by NHTSA to be in all RV trailer owner manuals.
