Tire-Track’s CVL-2 is an all rubber, permanent serialized, machine readable barcode label for new and used tires. This ID Unit allows the user to track virtually every aspect of tire management. It also acts as a deterrent to theft and helps minimize tire substitution. The CVL-2 label produces 25+ lbs of adhesion on the sidewall of a tire and survives the retread process. The information is "cut" into the rubber itself, so it won't rub off.
