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...

Perfectly normal IMO. My rear tires would get up to 95 psi from 80 cold running through 100 degree temps in Eastern Washington. Having said that, with small wheel wells that inhibit airflow, the inside duals are prone to getting too hot and failing from tread separation especially when loaded to max. I learned the hard way to use quality tires.
