If you've noticed that your tire pressure light is on inside of your vehicle, you're being alerted to an issue with one or more of your tires. This is something that commonly occurs as you drive your vehicle, but there are also problems that can take place with your tires. This would cause your automobile to alert you of a tire pressure change.
If you haven't filled your tires in a while, it might be time to do so. Make sure that you stick to the recommended level of air pressure in all four tires. Overfilling can put you in a dangerous situation when a blowout occurs.
If you've recently filled your tires, make sure that you haven't overfilled them. You may also need to drive around for a number of miles before your tire pressure monitoring system will reset itself.
