Since August 2019, Westlake has updated its tyre tracking system, in both sidewall of radial OTR tyres, there are serial number with QR code, anyone with smart phone can scan it and get the full serial number.

With serial number, we can trace production date and all the linked information, like raw material, green tyres checking record, machines and workshop operator.

The new Serial QR Code is big, easy to read, but hard to remove.
