Blowing tires on 5th wheel

I noticed one other thing now that I am reading all of the posts. I had the opportunity to be educated in, well, the limits of tire capability from a tire industry engineer, but related to auto tire capability. He told me that tires must be inflated to the sidewall pressure COLD. ON the day of use the tire must be at the psi on the sidewall for the maximum load carrying ability of the tire. I was told, absolutely, that no one would pass the driving course I was taking with the tire pressure less than the manufacture's sidewall pressure on the tire.DO NOT deflate it for smoother ride or any other reason. For whatever reason, in the course of my employment, I have scuffed a sidewall nearly to the wheel and I did not have a tire failure. I attribute not crashing in that situation to the advice I was given. Maximum load carrying capacity is AT the sidewall pressure for the COLD tire.
