Tire Air-Presure Preparation: timing
Silly question: We are getting ready for a short journey tomorrow afternoon; is it okay to check and fill the air in the trailer tires today; or, should I wait until tomorrow? Does it really matter?

you should check your air pressure when the tires are at the current outdoor air temp and not in the sun. If your traveling and do not expect the temps to change much a day before is ok , I check mine the night before when the tires are in the shade and the tire are cool, If you have a TPMS you will see the pressure go up as the tires warm up also the sunny side will have higher pressure than the shady side as you travel. its best to have them cool like the sidewall says xx psi cold
