Tire pressure increase at summer temperatures
I am fairly new to class A traveling so I'm seeing things for the first time.
Before I begin a trip my tires register between 101 and 104 psi on my TPMS. They are 16 ply and can handle up to 120 psi, but according to my axle weights I can get by with as little as 95 psi.
My TPMS is set to alarm at 95 psi and 120 psi. On my last trip of about 100 miles and ambient temperature at about 80, the high pressure alarm sounded. Upon checking, the pressures ranged from 112 to 121 psi. I expect temperature to rise when driving but am surprised at the amount of rise I get. I usually maintain a speed between 60 and 65. We often get summer temps here at 95+ in July and August, so I expect pressures to rise even more.
Just curious as to what others experience when driving in warm temperatures. Do you ever drop the pressure to maintain a pressure below recommended max or just go with cold pressure and not worry about rise?
