The Tire Pressure Monitoring System is designed to alert you when one or more of your tires are underinflated. Many people dismiss it as a minor issue, thinking that it’s not a flat tire. However, ignoring this warning can lead to serious consequences.

What Does the TPMS Light Mean?

The orange horseshoe symbol with an exclamation mark on your dashboard is a clear signal that something is wrong with your tire pressure. But did you know that the behavior of the light can tell you a lot about what’s going on? Here are three common situations:

  1. The light stays on: If the TPMS light remains on while driving, it means at least one of your tires is significantly underinflated. This is a sign you should check your tires as soon as possible.
  2. The light flashes: A flashing TPMS light usually indicates a system error. It could mean the sensors are malfunctioning, so it's best to have a professional take a look.
  3. The light turns on and off: This may happen due to temperature changes. Cold weather can cause a temporary drop in tire pressure, which might trigger the light. As the tires warm up, the light may go off again.

If you're unsure, you can always check your tire pressure yourself. Most gas stations have air pumps and gauges available for free. Make sure to inflate your tires to the recommended pressure found in your vehicle’s manual or on the driver’s side door jamb.

Why Low Tire Pressure Matters

Low tire pressure isn’t just an inconvenience—it can affect your car’s performance and safety. Tires are the only point of contact between your vehicle and the road, so keeping them properly inflated is crucial. When tire pressure drops, you may experience:

  • Increased wear on the tire treads
  • Reduced handling and control
  • Lower fuel efficiency due to increased rolling resistance
  • Decreased ability to disperse water, increasing the risk of hydroplaning
  • Potential tire failure, especially at high speeds

Ignoring the TPMS light can lead to costly repairs or even dangerous situations. Regular maintenance and checking your tire pressure can prevent these issues. If you’re unsure how to proceed, don’t hesitate to reach out to a trusted auto service center.
