Again, where is this written? I am an engineer; I know about designing with safety margins and worst possible case scenarios. I also know that that number was not taken from thin air (no pun intended) and is based on sound engineering and science. Exceeding it is like prodding the tiger and if your tolerances happen to line up in the wrong direction - and you will have no way to know that in advance - you are risking a possibly catastrophic failure. I'm sorry, but in my eyes it is a fool's errand and I have to strongly recommend against it.

This is from the DOT's website:
Maximum Permissible Inflation Pressure:
This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.

a true and reasonable max tire pressure cannot be advertised due to inaccuracies measuring the pressure coupled with the limited common sense of the person filling the tire so therefore the max rating has a VERY comfortable margin of safety built in
