Acme A564 Digital Pencil Tire Gauge

The Acme A564 is a Digital Pencil Tire Gauge. This durable and easy-to-use gauge displays pressure with a high degree of accuracy, ensuring longer tire life and improved gas mileage. A tire-pressure monitoring system (TPMS) is an electronic system to monitor the air inside a tire. TPMS delivers real time tire pressure information to the driver of the vehicle "“ either via a gauge or a simple low pressure warning light. These systems employ physical pressure sensors inside each tire and a means of sending that information from inside the tire to the vehicle instrument cluster.
