Question

What does TPMS mean?

Answer and Explanation

TPMS stands for Tire Pressure Monitoring System. It's an electronic system designed to monitor the air pressure inside your vehicle's tires. The primary goal of a TPMS is to alert the driver when tire pressure drops to a potentially unsafe level.

A TPMS usually works by using sensors located within each tire to measure pressure and temperature. This information is then transmitted wirelessly to a central control unit in the vehicle. If the pressure in one or more tires falls below a specified threshold, a warning light will illuminate on the dashboard, alerting the driver to the issue. Maintaining correct tire pressure is crucial for optimal vehicle safety, fuel efficiency, and tire longevity. Ignoring a TPMS warning could lead to poor handling, increased braking distance, and even tire failure.

There are two main types of TPMS: direct TPMS, which uses pressure sensors inside the tire, and indirect TPMS, which relies on wheel speed sensors used by the anti-lock braking system (ABS). Direct TPMS is typically more accurate, but indirect TPMS is less costly and doesn't require special sensors in the tire.
