Identify, serialize ' track your tires with the Tire-Track ID Unit from TIRE-TRACK LLC, a permanent all-rubber bar code label specifically designed for tires. Unlike other bar code labels that use ink or paint, the information is engraved into the multi-layer ID Unit, so it won't rub-off and the special additives prevent it from "browning out". The TIRE-TRACK ID UNIT is applied just like a "repair patch". It can be done at your location, during the retread process or even on a "green" uncured tire. Each ID Unit contains your company name, a serialized machine-readable bar code and the human readable interpretation. It works with most fleet maintenance or tire tracking programs.
