It was 25 when I went on my early morning walk around 6:40,today partly sunny temps in low 30's Sue
The tire pressure monitor light first started showing up in luxury cars in the late 90's but now is standard in all cars sold in the United States as of Sept. 01, 2007. It is time to introduce you to the Tire Pressure Monitor System (TPMS) and the sometimes pesky tire pressure monitor light.
Tire Pressure Monitor Light As we come out of fall and winter arrives, our temperatures begin to drop drastically over night. When it comes to our cars, steep temperature drops can trigger a sign of fall that we don't welcome: a yellow or orange low tire pressure warning light.We have good news for you, though. When your light comes on, your car is simply telling you that you need more air in your tire and this time of year, the warning is usually related to chilly nights.
Here's what's happening:
- Several vehicles that are 2000 and newer cars and trucks are equipped with a Tire Pressure Monitor System, which triggers your dashboard warning light when the air in your tires drops just a few PSI below the recommended tire psi.
To remedy your low tire pressure light, a simply check or adjustment of the air in your tires is all that is required.
- Your tire pressure will decrease about 1 psi for every 10 degrees Fahrenheit the outside air temperature drops. (Likewise, it increases about 1 psi for every 10 degrees when the temperature rises.) If your tire pressure was last adjusted during the day or after just coming off the road, the air pressure could be related to 90 degrees Fahrenheit. So now, the temperature drops over night overnight temperature hits the low 40s, your tire pressure will drop down by 5 psi, almost certainly turning on the tire pressure warning light .
I noticed my TPMS light came on this morning. I checked my tire pressures and they were all between 26 and 27. I usually set them at 35 when it's hot. I figure they are down from me not checking them for a long time plus the sudden drop in temperature, and that's why the light came on. I aired them up to 30 psi all around. I hope that fixes it. If not I'll go up to 32.
