Why Is My Tire Pressure Light On?

A car’s tire pressure light can come on for a variety of reasons. One of the most common is that the tire pressure in one or more of the tires has dropped below the recommended level. This can happen due to a slow leak, a puncture, or simply due to the tires losing pressure over time. Another possible reason for the tire pressure light to come on is a problem with the tire pressure monitoring system (TPMS) itself, such as a faulty sensor or a malfunctioning control module. If the light comes on, it is important to check the tire pressure and address any issues as soon as possible to maintain the safe operation of the vehicle.
Checking tire pressure is important for several reasons. Properly inflated tires can help improve a car’s fuel efficiency, which can save money on gas. They also help to maintain the safe operation of the vehicle. Under-inflated tires can cause the car to handle poorly and make it more difficult to control in emergency situations. Additionally, under-inflated tires can wear out more quickly and increase the risk of a blowout. Over-inflated tires, on the other hand, can cause uneven wear and make the ride less comfortable. It is recommended to check tire pressure at least once a month and before any long road trip. It is also important to check tire pressure when the tires are cold before the car has been driven.
