Definition of Size

The overview of Sidewall Markings for Motorcycles will be available here.

Initially they were only used to help identify the tire's make. Over the years, Government legislation has demanded safety markings be posted in order to help buyers know they are getting a legal tire.

Markings now fall into two main groups:

  • 1. Those essential markings which tire manufacturers have long used to indicate make, size and type.
  • 2. Markings which have been added over the years in order to respect the requirements of legislation.
