A Tire Pressure Monitoring System (TPMS) is a safety feature in vehicles that monitors the air pressure in each tire. It alerts the driver when tire pressure falls below a certain threshold, helping to prevent tire blowouts and improve fuel efficiency. TPMS can be either direct, using sensors in each tire, or indirect, using the vehicle's anti-lock braking system to estimate tire pressure. Maintaining proper tire pressure is crucial for vehicle performance and safety. Under-inflated tires can lead to increased wear, reduced traction, and higher fuel consumption. Regularly checking tire pressure, along with the use of a TPMS, can enhance driving safety and prolong tire life.
