The tire which has a tread containing cork particle

The present invention related to a tire， an unvulcanized state or a vulcanized one， having a tread that comprises a rubber composition. Such rubber composition comprises at least: a diene elastomer， 20 to 100 phr of a plasticizer， 20 to 150 phr of a reinforcing filler， more than 15 phr and less than 100 phr of particles of cork. Said plasticizer is chosen from the group consisting of liquid plasticizers， hydrocarbon resins and the mixtures thereof. In the vulcanized state， said cork particles have a median size by weight of more than 0.5 mm and less than 3 mm. In the vulcanized state， said rubber composition has a dencity of from 0.55 to 0.96g/cm3. The present invention makes possible a better anti-noise performance， especially regarding the coast-by noise， while maintaining or even improving the stability performance of the tire.
