what does tpms mean on a car?

TLDR: TPMS, or Tire Pressure Monitoring System, is a crucial vehicle feature that monitors tire pressure to enhance safety, fuel efficiency, and tire longevity. It alerts drivers to pressure changes, helping prevent accidents and improve vehicle performance.

The Tire Pressure Monitoring System (TPMS) is an essential technology in modern vehicles that monitors tire pressure and alerts drivers when it deviates from recommended levels. This system became mandatory in the U.S. for new vehicles in 2007 due to safety concerns. There are two types of TPMS: Direct TPMS, which uses sensors on each wheel to provide real-time pressure readings, and Indirect TPMS, which infers pressure through wheel speed sensors. Both systems aim to prevent issues like tire blowouts and improve vehicle handling.

The benefits of TPMS include enhanced safety, fuel efficiency, and tire longevity. Properly inflated tires contribute to better vehicle stability and reduced fuel consumption. Additionally, TPMS compliance is often a legal requirement, providing peace of mind for drivers. However, maintenance is necessary, as the system may require recalibration after tire rotations or sensor replacements. Understanding TPMS is vital for ensuring a safer driving experience and maximizing vehicle performance.
