Max Pressure Cold vs Hot Pressures - How Much Is Too Much

Folks worry way too much over simple things. Rving is suppose to be fun and exciting. I have been pulling for 50 years. I always set my tires to max inflation as the tire states. I may be jinxing myself but the only tire trouble I have had was the valve stem failed while I was backing into a site and the tire went flat. I expect a lot of tire failures are due to under inflation and the tire running too hot.
I am not knocking those who weigh, adjust psi regularly just expressing my thoughts.
