Abstract: A tyre comprising a layer suitable to ensure the sealing under pressure of the air contained in the inner cavity of the carcass and a foam material for sound absorption based on a polycondensate of polyphenolic compounds of natural or synthetic origins housed inside said inner cavity. Preferably, the foam material is based on flavonoid tannins.
