What is a Tire Pressure Monitoring System (TPMS) and How Does It Work?
A Tire Pressure Monitoring System (TPMS) is a device that monitors the air pressure in a vehicle’s tires. It alerts the driver when tire pressure falls below a predefined threshold, promoting safe driving and improving fuel efficiency.
According to the National Highway Traffic Safety Administration (NHTSA), the TPMS aims to enhance vehicle safety by preventing tire-related accidents caused by underinflated tires. The NHTSA mandates the installation of TPMS in vehicles manufactured after 2007.
TPMS functions using either direct or indirect methods. Direct TPMS uses sensors placed inside each tire to measure air pressure directly. Indirect TPMS uses the vehicle’s anti-lock braking system (ABS) to monitor wheel speed, inferring tire pressure by comparing wheel rotations.
The World Health Organization (WHO) emphasizes the role of tire safety in reducing traffic fatalities. Proper tire pressure can enhance vehicle handling, braking distance, and overall stability.
Tire pressure can drop due to temperature changes, leaks, or poor installation. Regular checking is essential. Studies show that about 30% of vehicles on the road have at least one under-inflated tire, leading to a significant increase in fuel consumption and tire wear.
Neglecting tire pressure can result in accidents and increased greenhouse gas emissions. Poor tire conditions contribute to approximately 11,000 accidents annually in the U.S., according to the NHTSA.
To mitigate risks, the NHTSA recommends regular tire pressure checks and maintaining recommended pressure levels. Drivers should also be aware of seasonal changes affecting tire pressure.
Implementing advanced TPMS technologies, such as smartphone integration and real-time alerts, can enhance tire monitoring. Additionally, educating drivers about tire maintenance can help promote safer driving practices.
