What many consider max pressure is NOT the maximum pressure. Read carefully, it is the pressure required to obtain the maximum load rating.
You can increase the pressure beyond what is on the sidewall but it does not increase load capacity beyond the rating.
When I had 50psi LRC (ST) tires, I regularly used a cold inflation of 55psi.
Maybe provide a tire manufacturers link to this please.
Read the side of your tire. It probably says something such as "max load xxxx at xx psi". Maximum load, not maximum psi.
Roger Marble of http://www.rvtiresafety.net/ has addressed this a number of times.
Here is one article he wrote that may or may not help in understanding;

Edit;
Here is a pdf from Goodyear about the 65 mph rating of Marathon tires. It speaks of increasing the pressure 10 psi in order to operate at 66 to 75 mph. The limiting factor on increasing the psi according to Goodyear is the wheel and the stem, not the tire.
