I left the dealership this past Friday, and hadn’t gone a mile until my “low tire” light came on. Don’t know how you would react, but my heart sank. So, I thought I would provide some insight about this feature. I had not given it any thought, but vehicle manufacturers began to phase in TPMS beginning in the 2006 model year and were required to install it in all vehicles manufactured after September 1, 2007.  I talked to one of our Service Advisors and asked for him to explain to me how the feature works: There are two kinds of monitoring systems direct and indirect. To keep it short and sweet, the direct system monitors the actual pressure in the tire while the indirect system uses existing sensors in the ABS system which watches wheel speed to detect smaller tire diameter caused by under-inflation.

So, the culprit that caused my light to come on? When the temperature outside the tire changes, it will affect the pressure inside the tire. In the fall, the colder weather will significantly lower your tire pressure. If your tire pressure has been set during the hot summer months, the first major cold wave will cause the air to contract inside your tire, lowering the pressure, thus setting off your TPMS.



Word of advice: To alleviate that annoying tire light, check your tire pressure monthly, during the morning, when tires are cold. During this time, make sure all tires are at the PSI indicated in your manual. Additionally, you might consider replacing the air in your tires with nitrogen. My Service Advisor explains: by using nitrogen the molecules are larger than oxygen molecules. Seepage is thus reduced through the tire walls and where the tire meets the rim. Any moisture in the tire is also eliminated, which can affect inflation.
