I like to fill the tires to the air pressure stated on the tire. Not more, not less.

A couple of thoughts:
I'll bet there were (and maybe are?) trailer manufacturers who are under-estimating the amount of stuff their trailer will carry - the payload. Maybe they were doing it in ignorance or maybe they did it to cheat on the regulations. Doesn't matter. The net result is the same - overload axles and tires. I recommend EVERYONE weigh their trailer.
Loads on tires vary front to rear and side to side - and that doesn't seem to be accounted for. I recommend folks weigh their trailer tire by tire - and if not possible, then add some sort of factor to account for this. Currently I am using 10% side to side variation - 10% front to rear - and 15% for both.
Tires should NOT be inflated according to the charts. Those are minimums! Use more than that. I like 15% more load carrying capacity - which is about 15 psi more for ST and LT tires (up a Load Range)
