I check/set mine for 115 PSI all the way around when not going down the road with them. When the tires are hot, I don't worry about it unless one looks like it is getting low. - no sense in over-thinking it.

I was waiting for this...me too, even at >20k lbs/axle.
If it is gettin too hot, I just slow down.
Over 110°, I won’t go over 50mph. On TX 2 lane blacktop in those temps, 45...
