I did a psi check on a trip several years ago. Tires on truck loaded with in bed camper wt of 4400 lbs rear axle somewhere around 7500 lb. Left pdx with 80 psi, outside air temps 40s. In Redding Ca. outside temp 110-115. Driven all day minus acouple short stops. Psi in rear tires was 96. I had no way to check the heat temp. of the tire. That was much more than I thought would happen. I guessed I would see a 8 to 10 psi change not 16. My speeds where 60-65, over big hills 50-55. Tire were carring max load, maybe even alittle more.
I am under the opinion that MOST blow outs are from under inflation and heat built up inside the tire due to under inflation or over loading. My opinion only.
