Tire pressures during temperature swings
I see a 3-4 PSI rise in my Ram 2500 tires from a cold start to highway driving after 30 minutes. During the day, if starting off from a cold location, to the hottest destination, do you account for...

"Cold" psi is when the tires have been in full shade for min. 2-3 hours. If you are setting the psi as per the sticker on door jamb, you'd have even less to worry about. You just don't hear about tire failures on TVs in comparison to ST tires on trailers (which should be run at max sidewall psi) which is often from being under-inflated. Losing air in a tire is the thing to worry about, not excessive pressure.
We have E rated tires on our F250 and I run 75 front & 80 rear (for better handling) and have towed many thousands of miles all over the western US and never an issue. At the end of the towing season I let some air out.
