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.

This same company the branded the max load at xxx inflation on your tires has a inflation table showing the tires load capacity at 5 pound increments. So if you know your weight then running less than sidewall inflation is recommended by companies like Michelin. Over inflation for the weight decreases contact patch and braking. It also subjects the tire to a higher chance of impact damage.

I will note many special trailer tire manufacturers do recommend full inflation, which I believe is a vailed attempt to make them last. Chris

So, you're saying that a tire below its max load and inflated to its max pressure is more susceptible to impact damage than one that's loaded to near its max load and psi?
