Sorry just not enough data. Tires do not fail due to average loading. You really need to know the actual load on each tire or at least on each axle. If you can't get individual tire loads then assume your motorhome axle is unbalanced at 47/53%

65 psi may or may not be enough air. It depends on tire size, type and the load on that tire.
If your tires have gone "out of round" there is a good chance they are in the process of separating. Get them inspected AT once. This does not mean a walk around the Rv and look at dread depth but measure Radial run-out and lateral run-out.
Read my post on tire inspection.

How often have you checked air pressure? Have you ever been low by more than 5 psi? Have you confirmed your pressure gauge is accurate to +/- 2 psi or less?
Why aren't you running a TPMS?

Pet?....lol, fact, but the experts here haven't replied or thought of that scenario so it has to be "Theory" Book smart vs common sense again!

There is a current thread in the International Rally forum with pictures of the tire failure on the tow dolly. The original incident that caused the tire failure is unknowingly explained by the thread starter.

Please go look up the definitions of "hypothesis" and "theory" in the scientific context. They are both often used incorrectly.

I have a theory about a hypothesis but fear it may be off topic, so.....
