2021 NEWMAR NEW AIRE Wheels Problems

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.
