While using the factory installed TPMS on my new aire with a spartan chassis, the tire pressures sometimes has an excess reading up to 170 degrees while driving and increases when stopped. I can rest my hand on the tires without any trouble so I'm sure it is not as hot as it states and I check the pressures with a gauge daily before driving, all pressures are correct. Sometimes after several hours of driving I get all normal readings and other times after only 2 hours it will say 4 of 6 tires are overheating, only the rear tire sensors so far. This has only happened on the highway at highway speeds, not in town.
