Tireman9 Posted June 25, 2020 Report Share Posted June 25, 2020 I have seen people comment on TPMS and using IR guns for checking tires. IMO as an actual Tire Design Engineer, Checking air pressure only tells you you have air when you are doing the check. A Single air leak (nail, cut valve leak etc) can do $thousands of dollars) when the tire runs flat. Even running low will increase operating temperature and increased temperature will accelerate tire aging rate with the aging doubling every increase of 18°F. Have even seen air loss due to valve core leak because a plastic valve cap was used because metal cap was too expensive. TPMS is an investment as they can be moved to any other RV or even sold. This makes them better than Insurance as the one time purchase only requires replacement batteries (50 ¢ to $1 each at Amazon) once a year or so. Don't worry about IR for checking tires. Rubber is an insulator so IR does not give you the information you need regarding tire temperature. IR is fine for checking metal components (hubs & brakes) Of course you need to run the proper inflation (based on measured load plus a small Reserve Load) and you need to set your TPMS warning levels for your personal situation.
