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...

Tire pressure "cold" is as the others have said, cold in morning before driving and hot sun hitting tires.
We had an issue once on the MH. I set the cold pressure to 70front 80rear the morning we left Ontario for Florida. Ambient temp was -22F. 2 days later after having bad handling problems, very rough ride, I checked the tire pressures next morning cold, ambient temp 72f and the pressures were up to approx. 85 and 95. Yes I did bring them down to the appropriate pressures, and he handling and ride returned to normal.
Also in the CRV, it calls for cold pressure of 31psi, but the TPMS alarms at 29psi. With the temperature swings in this area in spring and fall 50f to -5f in a couple of days, i just increase the cold pressure to prevent the TPMS from alarming.
