If your tire pressure light is illuminated, there are a number of reasons why this could be occurring. It's important that you don't ignore tires that need air added (or removed). You could end up with a flat tire, tire blowout, or damaged tire if you aren't careful. Here are some of the most common reasons for an illuminated tire pressure light.
-Your physical tire pressure monitoring system or tire pressure sensors in each tire could have a malfunction that's causing your light to come on. If you fill all of your tires, drive around and the light remains on, you'll want to make an appointment to have the issue addressed.
-Colder temperatures can cause the air in your tires to condense. You may require a little bit of extra air in the winter months in order to keep everything at an appropriate level.
