TIRE-TRACK LLC offers two different ID Units for your specific needs, either one can include the optional RFID tag…. Which ID UNIT is right for you?     2BT: The original ID Unit.  It is designed specifically for a tire and is constructed similar to a “repair patch”.  It is applied with cold-cure vulcanizing cement (approximately 15lbs of adhesion) or by heat (approximately 45 lbs. of adhesion) and easily withstands the retreading process.     2SI: Our next generation ID Unit.  It is designed for tires and most other rubber based products (rubber gloves, boots, rafts etc.).  It is attached to a tire or other product using our special “super glue” (approximately 45 lbs of adhesion).  The SI installation process is quicker, easier and more forgiving than the BT product.  Currently, the cement does not withstand the retreading process and therefore, must be reapplied after retreading.     2SAS: For those customers who are interested in RFID technology, TIRE-TRACK LLC offers the option of including an industry approved RFID tag in either ID Unit.  The RFID tag contains the same number that is presented on the barcode and eye-readable number; therefore, there are multiple means of identifying the tire.  The RFID chip is either ISO or Gen2 compliant.
