What is the purpose of the tire pressure monitoring system (TPMS)?

Answer: B — To alert the driver of low tire pressure

The purpose of the tire pressure monitoring system (TPMS) is to alert the driver of low tire pressure. Maintaining proper tire pressure is crucial for vehicle safety and performance, as underinflated tires can lead to increased tire wear, reduced fuel efficiency, and a higher risk of tire blowouts. The TPMS continuously monitors the pressure of each tire and provides warnings when the pressure falls below the recommended levels, allowing drivers to take action before a more serious issue arises. While measuring tire tread depth, assisting in fuel efficiency, and indicating tire rotation needs are all important aspects of vehicle maintenance, they are not the primary function of the TPMS. The system specifically focuses on tire pressure, which makes it an essential component for safe driving.
