Attaching radio frequency tags to tires could help better target recalls and provide an early warning system of defects, an executive of a firm that produces the tags said Tuesday.
The thin, metallic tags actually look more like strips, which manufacturers would attach to the inside of the tires. Contained in the tags would be a small memory chip and a radio frequency transmitter. The memory chip would be programmed with information regarding the plant where the tire was made, the date and time the tire was produced, and the tire’s dimensions, known as conicity. When the tire is installed on a new vehicle, the car company would add the vehicle’s identification number, or VIN, to the tag’s memory, information required by federal law. Information contained on the tag could be read from as far away as six feet with a special radio frequency receiver. The information is also downloaded into a computer to form a database “marrying” every tire to the vehicle on which it’s installed.
