Don't worry about it the tire manuf have taken this into account when they build their tires. They know the tire well heat up in the summer but they recommended tire pressure is to be set cold. So set them cold and then don't worry about them unless you have them overloaded then this can cause them to heat up also. When I had my 5th wheel on a 80 PSI tires on it I would see tire pressures in the 90# range also when I started with 80 in the tire and the my tires were not overloaded. I run a Doran TPMS and like to watch it also.
