Once rolling around 55mph they cooled down to 51# psi and about 99 degrees.
Trailer tires got up to 57# psi and 105 in traffic and 97 once we were traveling.
Was interesting just seeing what they did on a 90 degree day.

Now on mobile phone so dont have speadsheets for temp/ pressure at hand.
But the pressure rising is not in line with the temperatures.
So I think you have sensors screwed on the outside on valves. This gives temp somewhere between in an outside tire temp.
At the stop you probably measured higher temp and pressure because yust after braking , wich heat is transported trough the rimms to the tire inside.
When I am on my handicapped laptop, I will give a tabel of pressure for temp.
