Tagging car Tires - update
Update in November 2004
The Automotive Industry Action Group's Tire and Wheel Label and Radio Frequency identification Standard will now include the EPCglobal data format for RFID tags used to identify tires and other auto products. It is hoped that tire manufacturers will not have to produce up to 12 different labels and identification marks for each tire to meet disparate customer needs. The move to RFID should mean that tire manufacturers will need only one tag per tire.
Auto parts generally
It is expected that tags based on the new standard will be used on many auto parts but tagging tires was the key driver behind bringing AIAG B-11 standard into line with the EPCglobal numbering system. AIAG's Tire and Wheel label and Radio Frequency Identification Standard was the first item level RFID standard in the world when it was released in 2001.
Data format defined at last
However, the data format was not defined until the recent decision to embrace EPC. AIG revised the standard to allow OEMs and tire suppliers to include retail information such as manufacturer and product and serial number in the RFID data. A data identifier will now support a 96 bit EPC number in the AIAG standard. In principle it can also be used in barcodes and other identifiers.
About 323 tires are sold every year in the US market and that figure will be 356 million units in 2009 according to the US Rubber Manufacturers' Association. There are about 1250 billion tires in the world and output globally is probably 650 - 700 million or so.
