You jump into your car, get ready to go and then you notice on your dash board a little yellow or red symbol light up. Your first thoughts are; “I do not have time for this”,or “How much is this going to cost me?” Once you find your owners manual, you learn that the symbol is a Tire Pressure Monitor or TPM. You look at your tires and think “they look just fine to me.”
It is much like what the New England Patriots and referees thought about the footballs during that famous Deflate gate game. So off you go to your local auto repair facility seeking help and answers. That is where you learn that the air temperature has a direct impact on the pressure in your tires. Colder air makes the pressure or PSI shrink some in your tires. It is actually the same theory that the New England Patriots used in their defense of the deflate gate game (nytimes.com). Your auto repair facility will inspect your tires usually visually first, some may use a tire gauge to check on the actual amount of pressure in your tires, and many newer model vehicles have a display on the dashboard that reads out the pressure in the tires. It is normal for vehicles tires to be up or down a few pounds of PSI without there actually being a problem with a tire. If all seems fine the customers will probably be told to continue driving the vehicle and once the tire and or temperature warm up some the light should reset itself.
In the year of 2006 the government made a regulation that all vehicles need to have Tire Pressure Monitors or TPM on board. These monitors were put into vehicle tires to help keep us safe, if a tire were going low it could impact the way a vehicle responds while driving. Another reason they are in vehicles was to improve the gas mileage as properly inflated tires help the vehicle ride more smoothly and evenly.
The best advice is that you should look at your tires, if one looks off then have it checked out. If it happens right after the weather drops some 20 degrees chances are the light will go off once the tire or weather warm up.
Happy driving and safe motoring.
