Truck's recommended tire pressures for max load should be set, based on 70 degrees F, for most accurate setting. We have a 5th wheel and dually, with TPMS on all tires. Tire pressures on the truck will rise as much as 12 psi when towing in 90 degree weather. 5th wheel tire pressures will rise as much at 18 psi, when it's hot. Pressure and temperature rises are expected by the tire manufacturers. If you are still concerned, go to the website for your tires, and ask the experts.
