  • Load index and speed rating: These numbers indicate the maximum load the tyre can carry and the maximum speed it is rated for, respectively.
  • DOT code: This is a code issued by the Department of Transportation (DOT) that identifies the manufacturer, plant, and date of production of the tyre.
  • Treadwear rating: This is a number that indicates how long the tyre is expected to last compared to a standard reference tyre.
  • Traction and temperature ratings: These letters indicate the tyre’s ability to stop on wet roads and its resistance to heat and degradation, respectively.
  • Maximum inflation pressure: This is the maximum amount of air pressure the tyre is designed to handle.
  • M+S or snowflake symbol: This indicates that the tyre is approved for use in winter conditions.
  • Other symbols or markings: Depending on the tyre, there may be additional symbols or markings indicating special features like run-flat technology, reinforced sidewalls, or eco-friendly materials.

It’s important to pay attention to this information when selecting and maintaining your tyres, as it can affect the tyre’s performance, safety, and longevity.
