Tyre bead labels are barcode labels applied to the bead of the tyre either pre or post-vulcanisation. These unique identifiers act as a license plate for the tyre throughout the manufacturing process.
Barcode labels applied prior to vulcanisation are also referred to as vulcanised tyre labels.
Tyre specific details such as date of manufacture, safety and performance ratings, etc. are tracked using the barcode.
Additionally, bead labels can function after manufacturing has been completed. Some automated tread label applicators source information from the bead barcode as tyres pass through integrated scanners— providing variable data needed to print the tread label.
