Common Meanings of Your Tire Pressure Warning Light

When your tire pressure warning light begins to signal an issue with your tires, it’s important to know what it means in order to take the necessary action. A few common meaning of your tire pressure warning light include:

1. Lights Up While Driving

If the tire pressure warning light lights up while you’re driving, this signifies that at least one of your tires has low air pressure or that a tire is going flat. This could be due to cold weather, a slow leak, or recent damage to one of your tires. It's a good idea to stop and check your tires for low pressure or any punctures.

2. Light Flashes On and Off

If you notice your tire pressure warning light flashing on and off, this could be an indication that the air pressure is fluctuating in at least one of your tires. This can occur often in the Midwest with frequent fluctuating temperatures and could also occur when you drive at high speeds for a long period of time, as this heats the tires and affects the tires’ air pressure.

3. Light Flashes and Then Stays Lit

If your tire pressure warning light flashes and then stays on, even after you’ve identified and resolved the issue, there could be a problem with your tire pressure monitoring system. It’s important to have this checked out by a professional, as this could be dangerous as your tire pressure monitoring system will no longer notify you when your tire pressure lowers or fluctuates.
