The tires on my 5th wheel state 80 psi max. I run 76 to 78. What should I set upper psi setting and lower psi setting on my tire pressure monitor system ?
I don't have a TPMS but the IR temp gun I have shows an easy 40+ degree temp increase, with about 20 degrees difference between sunny and shaded sides, when towing here in AZ in the summer. One reason that I've always kept my tires within 5 lbs of max cold psi, even when I went up a load rating.
