Tire pressure fluctuation when hot
Via my tire pressure monitor kit, I noticed that my tire pressures in all 6 tires increased uniformly by as much as 18psi from cold pressure on a long trip thru the desert. Is this normal? I drive...

on our fifth wheel just a few weeks ago the pressure started out at 64psi and 66 deg temp. The highest pressure I saw was 77psi at 134 deg temp, ambient temp was 105 deg and sunny all day, running 60-68mph. Tires were well within their load range running at approx. 2100lbs out of 2520lbs capacity.
Ambient air temp may have been 105 but road temp could have easily been 115-120
