What is TPMS (Tire Pressure Monitoring System)?

The yellow light on your dash with an exclamation mark in the middle is your TPMS indicator, also known as the tire pressure monitoring system. Your TPMS monitors the air pressure in your tires and alerts you when one (or more) of them drops 25 percent or more below its recommended pressure.

Should I Be Concerned When My TPMS Light Comes On?

 Your TPMS light will typically come on when the weather has gone from somewhat warm to stark cold. Drastic changes in temperature could deplete or inflate air pressure in your tires causing your TPMS sensor to trigger.
  • Gas mileage will go down   
  • Shortened tire life due to uneven tread wear   
  • Decreased ability in steering handling   
  • Tire blowout due to stress from under-inflation

What If My Car Doesn't Have a TPMS Light?

Not every car has a TPMS sensor to warn you about low air pressure in your tires. If this is the case, then develop a habit of checking your tires at least every 3-4 months.

Maintain Proper Tire Inflation

Even if you have a tire pressure sensor, it's important to check your air pressure regularly - as your vehicle's age and other factors can impact the system's readings. If you get the TPMS warning, fill the tire to spec.
