Most of us are aware that each tire has a TPMS (tire pressure monitoring sensor). When the tire monitor light comes on it is telling you that one of the tires has low pressure, but did you know this also includes the spare tire?
When checking your vehicle’s tire pressure, be sure you are also checking the spare tire. Many vehicles have a monitor in the spare as well. So even if your four main tires are spot on with their tire pressure, the light could be on to alert you about the spare tire.
If all 4 tires and the spare tire are OK, then most likely you have a TMPS that needs replaced. You local mechanic can find out which one is the culprit and replace it for you.
