Back to what I believe the intent of the thread was.
I left MN in the morning a couple days ago at about 10deg out. Tires were aired to 60 steer, 80 drive, and 95 trailer. Pulled south to TX and thought about adjusting pressures down a little as morning temps have risen 30+ dregs, but I was lazy and waited until we've been in camp here a while today. With temps around 70 my tires were all 10-12psi high. Lowered them to ~2psi high and will check in morning where I expect I'll be happy with them for the duration of the "winter", if you can call it that here in TX.
