Tire pressure in trailers....

Is the reading on the sidewall (80 psi max) a cold temperature rating or a maximum the tire can withstand when it is hot? I have always wondered about this.

If I had to guess it would be a cold (rested) reading and the tire should be designed to withstand pressure increase due to temperature increase caused by on the road use. But this is my guess. Does anyone really know?
