I don't know what the problem is? You look at the pressure/weight table the manufacturer publishes and follow their information. They knoe best. Weigh you truck and know what weight is on the tires. Add about 10% and run that pressure. The tire sidewall will tell you max pressure only. The door stricker is a general guide.

My weights say I should always have 65 psi in the front tires. I run 55 psi unloaded and 80 psi with the 5th wheel loades. My trailer weights say I could run 70 psi in all tires but I run 80 psi because of differing water loads. My trailer sidewalls say I can go to 110 psi but that would be like driving on steel wheels. I don't want to beat my trailer up.

My sin-in-law pulls heavy trailers all the time. He has found in the hot desert if he runs full tire pressure he has more blowouts.
