What Does TPMS Stand For?

A TPMS, or Tire Pressure Monitoring System, is an electronic system employed in most modern vehicles to monitor the air pressure inside your tires. This system is vital in ensuring the safety and maintenance of tires. In fact, Congress implemented the TREAD Act in 2000 to ensure that all vehicles made in 2006 and after that are equipped with TPMS. 

 

How Does TPMS Operate?

There are two main types of systems used in vehicles today: Direct TPMS and Indirect TPMS

  • Direct TPMS - This type uses sensors within each tire that monitor specific pressure levels, not from the anti-lock brake system. When air pressure falls 25% under the manufacturer's recommended level, the sensor transmits the data to your vehicle's computer system and triggers your dashboard TPMS light to come on.
  • Indirect TPMS - This type of system works with your vehicle's Anti Lock Braking System's (ABS) wheel speed sensors. If a tire's pressure is down, it will roll at a different wheel speed than the other tires. This information is recognized by your car's computer system, which also flicks on the dashboard indicator light.

What Are the Advantages of TPMS?

The TPMS lets you know when your vehicle's tire pressure is low or is approaching flat. By helping you hold a proper tire pressure, TPMS can improve your safety on the road by enhancing your vehicle's handling, reducing tire wear, lowering braking distance, and increasing your fuel economy.

 

Though the TPMS is a magnificent feature in modern cars today, you should not solely rely on the system for tire maintenance. You should definitely still take some time to check your pressure with a gauge and use your eyes to inspect treadwear and punctures on your tires. If your TPMS light comes on, please attend to it as soon as possible. Our expert team at County Line Auto Service will be glad to help! Give us a call or visit today.
