What is a Tire Pressure Monitoring System (TPMS) and How Does It Work?
A Tire Pressure Monitoring System (TPMS) is a safety feature that continuously monitors the air pressure inside tires. It alerts the driver when tire pressure falls below a predetermined threshold.
According to the National Highway Traffic Safety Administration (NHTSA), TPMS serves to improve vehicle safety and fuel efficiency by ensuring optimal tire pressure.
TPMS operates using sensors in each tire that detect pressure levels. If the pressure drops significantly, the system triggers a warning light on the dashboard. There are two main types: Direct TPMS, which uses sensors to measure pressure, and Indirect TPMS, which estimates pressure using wheel speed data.
The American Automobile Association (AAA) further defines TPMS as a system that helps prevent accidents caused by under-inflated tires, which can lead to blowouts and reduced vehicle control.
Causes of tire pressure loss include temperature fluctuations, punctures, and natural air leakage. Each tire loses about 1-2 psi (pounds per square inch) monthly due to normal conditions.
A study by the NHTSA revealed that under-inflated tires contribute to 660 fatalities annually in the U.S. It also noted that proper tire maintenance can enhance fuel efficiency by 3.3%.
Under-inflated tires can result in increased fuel consumption and decreased vehicle handling, leading to economic losses and safety hazards.
Solutions include regular tire pressure checks, adhering to manufacturer recommendations, and utilizing tire pressure gauges.
