This may help. As I understand it, the maximum pressure rating applies to "cold" inflation only, and it's expected that if tire started the day at maximum pressure, then it will go over that rating due to temperature. That's normal and expected as far as I know for truck tires also.

It's important to note that much of the temperature rise in tires comes from within the tire due to the constant flexing of the tire, not just from ambient. Much of that energy the engine has to produce to overcome rolling resistance ends up as heat in tires. That's why the faster we drive the hotter tires get, assuming everything else remains equal.
In no case should air be bled off to lower pressure because of this. If that were done, the tire would then get hotter, eventually leading to failure. High tire temperature is usually the biggest problem.
