TIRE-TRACK LLC offers two (2) different ID UNITSTM for your specific needs…. Which ID UNIT is right for you?     CVL-ID UNIT: The CVL-ID UNIT is a permanent all-rubber bar code label specifically designed for tires, it is constructed similar to a repair patch.  Unlike traditional "peel-n-stick"  or other rubber labels, the information is cut into it, so it can't rub-off.  It is either chemically or heat vulcanized to the tire and easily survives retreading. The CVL-ID UNIT is intended for those fleets that retread their tires.     SI-ID UNIT: The SI-ID UNIT is an all rubber bar code label designed for "harsh environments" that can be applied to almost any surface, including tires. It is intended for applications where a traditional "peel-n-stick" vinyl label or anodized aluminum plate either does not work or isn't appropriate. The SI is not affected by pressure washers, cleaners or degreasers and is ideal for sanitary applications. The SI is bonded to the surface with industrial "superglue." The bond is incredibly strong, quick and easy to apply. The SI-ID UNIT does not withstand the retread process; therefore it is intended for those fleets that do not retread their tires.     DEMO KITS: Demo Kits are available for both the CVL and SI Product(s). Each kit includes 15 samples and everything you need to properly apply them. (Contents may vary).     SAS: 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 SAS chip is Gen2 compliant.
