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

I think some of the tire inflation, disagreement, is due to talking about many different types of tire use. What works for cars, trucks, DRW trucks, motorhomes, and trailers, is not comparing apples to apples.

Most put the proper tires on their tow vehicle, and adjust as needed for load. I see some people buying way more tire than their trailer needs, then reducing pressure, way below max, when they should have just purchased the proper tire needed for the load, and aired for the load.
