What Is a TPMS System and How Does It Work?

A Tire Pressure Monitoring System (TPMS) is an electronic system designed to monitor the air pressure in a vehicle’s tires. It alerts the driver when tire pressure falls below recommended levels, improving safety and fuel efficiency.

The National Highway Traffic Safety Administration (NHTSA) defines TPMS as a system that “provides real-time monitoring of tire pressure in order to prevent tire failure.”

TPMS employs sensors within each tire to measure pressure. This information is transmitted to the vehicle’s onboard computer, which calculates whether the pressure is within safe limits. If the pressure is too low, a warning light activates on the dashboard.

According to the Tire Industry Association, proper tire pressure minimizes tire wear and enhances vehicle handling. Maintaining recommended pressure improves gas mileage and reduces the risk of tire blowouts.

Common causes of low tire pressure include temperature changes, punctures, and slow leaks. Seasonal temperature fluctuations can reduce pressure by about 1 PSI for every 10-degree drop in temperature.

Statistics show that under-inflated tires significantly contribute to vehicle accidents. The NHTSA reports that proper tire maintenance could prevent up to 10,000 accidents annually.

The consequences of improper tire pressure include increased vehicle accidents, higher fuel consumption, and environmental damage. Poor tire pressure contributes to greater CO2 emissions and reduces overall vehicle lifespan.

Incorporating regular tire maintenance and using TPMS can mitigate these issues. The NHTSA recommends regular pressure checks and timely repairs for punctures to preserve tire function and safety.

Additionally, utilizing technologies like automatic tire inflation systems can proactively maintain tire pressure, enhancing safety and efficiency.

How Is Vehicle Safety Linked to the TPMS?
