I know the recommended cold pressures for my truck & trailer. Truck is 80 rear and 65 front. Trailer is 80.
I set them all on a nice day in the shade (so one side didn’t heat from morning sun).
A few days later, while checking pressures before heading out, it was 30 deg colder so the pressures were down 5lbs. A couple of miles down the road and all were at 80 & climbing.
The question is, given in my travels, each morning brings large differences in morning temperature, do I need to reset all the tires back to 80 each travel day? During travel in moderate temperatures the trailer tires all seem to run at about 90lbs depending on the sun.
