Reasons Your Tire Pressure Light is Illuminated

It's tough to know how much air pressure is in your tires just by looking at them, which is why modern vehicles come equipped with tire pressure monitoring sensors. These sensors gauge your tires' pressure and tell you when it's a little too low by illuminating a handy light on your dashboard. Unfortunately, this system isn't perfect. Your tire pressure light will go on when your tire pressure is low, but it might go on for other reasons as well.

Temperature Changes

When you start your car on a cold day, the tire pressure light sometimes turns itself on. This is because your tire pressure will actually drop slightly in colder weather. As you drive, the air in the tires will heat up and expand, which will turn off your tire pressure light after about five minutes of driving.

Leaks and Punctures

Of course, your tire pressure light might come on if you have a slow leak or a puncture in any of your tires. This means that your tire pressure system is doing its job. If your tire pressure light turns on and stays on, you probably have a problem that needs to be checked out.

Whether your tire pressure light is constantly illuminated or you just feel like your tire pressure isn't great, bring it to a dealer or mechanic who specializes in tire changes. Odds are good that you need some new tires, especially if it's been a while since you've bought a new set.
