The max pressure is really a max recommended pressure. If the pressure is too high, a couple things could happen:

1) the tire could blow off the rim.
2) the threads in the case of the tire could break.

Usually the tire will blow off before the rim will blow apart. The exception is very worn rims (worn from rim brakes). I have heard of instances when air pressure can blow a weakened rim apart.
