Continental Tires PSI rising 20
I recently bought Continental 255/70R 22.5's for my Tradewinds, it has always ran Michelins but none were available. I'm traveling from Southern Utah to Southern Arizona and am running 100psi in all ...

Pressure increase is directly related to the air temperature (and the outside air pressure); it's a simple matter of physics and has nothing to do with the brand of tire. Assuming basically dry air, it very nearly obeys the ideal gas law. Water vapor causes some deviations from the ideal behavior as at typical tire temperatures and pressures water doesn't quite respond as an ideal gas. Maybe the air you have in the tires isn't particularly dry.
If you've driven up a mountain, the increase in altitude will cause a small increase in measured tire pressure since the atmospheric pressure goes down a bit. It's not a huge difference, less than 5 psi for any road you're likely to encounter.
