Hello quick question. My trailer tires instruct me to use 65 psi when cold. Well some days I start in the 30's and some days in the 70's. And for argument sake, let's say both of those days end in the 90's. I know from using my tire temp and pressure monitor that if I put 65 psi in at 30 degrees and ran it to 90 degrees it would be different than if I put it in at 70 degrees and then ran it to 90 degrees. So should I be aiming for 65 psi for the temp I would spend most of the day towing at, or?
Thanks in advance!
I have 225/75/17.5 tires, put in 120psi at 65 degrees after 300 miles with air temp at 80 degrees pressure went to 140 psi and temp was 90s; after a night a 7500 ft air temp was 45 degrees pressure was 116 psi drove 400 miles cruising at 70 mph outside air was 95 degrees, tire temp was 106 degrees and air pressure was 146 psi that is with my TST TPMS
