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...

The physics of pressure and temperature is PV = RT
V is volume of air in the tire, R a constant, T the temperature in Absolute degrees, 273 plus the Celsius temperature. Where summer is 27 C higher than winter, T is 10% higher which causes Pressure to be 10% higher by the formula. I think best to do some morning adjustments before driving during spring and fall.
