A tire-pressure monitoring system (TPMS) is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. The V-checker® TPMS device T501 reports real-time tire-pressure information to the driver of the vehicle via 4 inches LCD screen with multiple warning lights so as to avoid traffic accidents, poor fuel economy, and increased tire wear due to under-inflated tires through early recognition of a hazardous state of the tires.
