The optimal tire pressure best supports your vehicle, ensures comfort, and helps your tires grip the road. If the pressure light is constantly illuminated on your dashboard, it can mean several things. Here are potential reasons and when to see an auto mechanic to resolve the problem.

Why Your Tire Pressure Light Is Always On

1. Air Leaks

The tire pressure light activates when your tire pressure dips below the recommended air pressure. If you’ve recently filled the tire and notice the light is back on, it may signal a leak. Use a pressure gauge to check for a pressure drop. You can then spray the tire with soapy water. If you find a spot that’s bubbling, it indicates a leak. You may also find nails, screws, or other items stabbed into the tire. An auto mechanic can provide tire patching if possible. If needed, they can also sell and install a replacement tire.

2. Temperature Changes

Constant temperature swings impact the density of the air in the tire. Cold temperatures, for example, could cause a pressure change, and the light will come on. You’ll then see that when it warms up, the light comes on intermittently during the day and then stays on when the temperature drops again at dark. While it may be the only cause, it’s still best to check the tire pressure and to check for leaks to ensure the change is only weather-related.

3. Damage Sensors

If you’ve recently driven on a bumpy road or uneven surface, the pressure detection sensors on your vehicle may have been damaged. The light will stay on longer if they aren’t reading tire pressure correctly, so you’ll need to schedule an inspection with an auto mechanic. Sensors always fail after 5-10 years of use. Ask your mechanic to test yours during your next inspection so you know they’re still reliable.
