closeup of a car tire While many drivers overlook the TPMS light on their dashboard, it’s actually one of the most important indicators for your safety and vehicle performance. The Tire Pressure Monitoring System (TPMS) alerts you when one or more of your tires are underinflated. Some people might think that as long as the tire isn’t completely flat, there's no need to worry. But ignoring this warning can lead to serious consequences.

What Does the TPMS Light Mean?

The orange horseshoe symbol with an exclamation mark is a clear signal that something is wrong with your tire pressure. However, the behavior of the light can tell you more about the issue. Here are three common situations:

  1. The light stays on: If the TPMS light remains illuminated while driving, it means at least one tire is underinflated. This is a direct alert from your car’s system that action is needed.
  2. The light flashes: A flashing TPMS light could indicate a malfunction in the system itself. It may be a sensor issue or a communication problem between the sensors and the car’s computer. In such cases, it's best to have a professional check the system.
  3. The light turns on and off: This might happen due to temperature changes. For example, if you move from a cold environment to a warmer one, the air inside the tires can expand, causing the light to flicker. However, it’s still a sign that the system is detecting a change in pressure.

If you see the TPMS light, you can take a quick step to check your tires. Many gas stations offer air pumps and tire gauges so you can inflate your tires back to the recommended pressure. Always refer to your vehicle manual for the correct PSI values.

Why Low Tire Pressure Matters

Low tire pressure isn’t just a minor inconvenience—it can significantly affect your driving experience and safety. Tires are the only part of your car that makes contact with the road, so their condition plays a huge role in how your vehicle handles. Here are some effects of underinflated tires:

  • Increased wear on the tire treads
  • Reduced handling and control
  • Decreased load capacity
  • Lower fuel efficiency due to increased rolling resistance
  • Higher risk of hydroplaning in wet conditions
  • Potential tire blowouts or failure

Ignoring low tire pressure can lead to costly repairs and even dangerous situations on the road. Regular checks and maintaining proper inflation are simple steps that can save you time, money, and stress in the long run.
