The value listed on the tire is max COLD inflation pressure that the tire was designed to safely handle. The actual (warmed up) pressure will be a few PSI higher once you start driving on the tire, and that's OK. The tire manufacturer already took that into account.
But the hot tire pressure can vary greatly, the hotter the ambient the higher the pressure.
This is why the fixation here on what the manufactures put on the door jam is so inconstant with reality. They do that more for ride comfort that performance or safety.
