Tire pressure (temperature) increase while driving

I always run near the maximum tire psi as written on the sidewall . My tires run cooler which tells me that I will have less tire problems . All the tread on my tires is in FULL contact with the road as I have confirmed this visually .I get extremely long miles out of my tires that wear very evenly . This tells me the tires "like" the way I treat them with max pressure in them . Sure the ride suffers .
I'm hunkered down now and waiting in the bunker for the inevitable "incoming".......:)
