What Is a Tire Pressure Monitoring System (TPMS) and How Does It Work?

A Tire Pressure Monitoring System (TPMS) is a safety feature that monitors the air pressure in a vehicle’s tires. It alerts the driver when tire pressure is too low or too high, enhancing road safety and fuel efficiency.

According to the National Highway Traffic Safety Administration (NHTSA), TPMS is required in all new vehicles sold in the United States since 2008. This regulation aims to prevent accidents related to tire under-inflation.

TPMS operates through sensors located in each tire. These sensors measure air pressure and send real-time data to the vehicle’s onboard computer. If the pressure falls below a specified threshold, a warning light illuminates on the dashboard.

The Federal Motor Carrier Safety Administration (FMCSA) defines TPMS as a system designed to monitor tire pressure and provide necessary alerts to prevent tire blowouts. It highlights the importance of TPMS in ensuring optimal vehicle performance.

Low tire pressure can occur due to temperature changes, punctures, or long-term wear. Seasonal fluctuations often contribute to tire pressure changes, as colder temperatures can decrease pressure.

Research from the Rubber Manufacturers Association indicates that approximately 20% of vehicles have at least one tire under-inflated by 25% or more. Proper inflation can improve fuel efficiency by 3% to 4%.

Improper tire pressure can lead to accidents and increased tire wear. It also contributes to higher fuel consumption and emissions, impacting environmental health.

Consequences include increased repair costs, higher fuel expenses, and greater risk of road accidents. These impacts pose economic burdens on society.

Examples include accidents caused by tire blowouts and increased emissions from under-inflated vehicles leading to air quality degradation.
