The last two numbers identify the year of manufacture e. For tires manufactured prior to the year , three numbers instead of four indicate the date of manufacture.

The alpha numerical coding on the sidewall of Dunlop motorcycle tires can be confusing.

Advances in the materials used have developed dramatically, with new elements offering manufacturers multiple options for both carcass design and compound variation. The traditional balance of a hard compound for mileage and a soft compound for grip has been modified by additional elements that make the rubber behave in very different ways.
