Your Keystone owner's manual will tell you to seek information/recommendation/approval from the trailer manufacturer. That owner's manual information is there because NHTSA mandated it to be there.
Bottom line: In the tire standards, rules, regulations world, only the vehicle manufacturer or a certified vehicle modifier have the authority for size/design/options changes.

These organizations that control all of this are giant bloated buerocratic agency’s that are slow to change and mired in rules that are probably 10 years behind actual present day manufacturing processes. I do appreciate your wisdom and knowledge in all of this but it’s hard to take anything seriously from agency’s that probably run like the post office in a perpetual deficit. Anyway thank you for taking the time to answer my questions!
