<p>The invention relates to a twin tread tyre comprising: a carcass (1) having an essentially-U-shaped transverse section; an outer tread (2) on the outer wall of the carcass (1), comprising drainage channels (3); and an inner tread (7) on the inner wall of the carcass (1), comprising drainage channels (8), such that the outer (2) and inner (7) treads together with the carcass (1) form a single body. In addition, the carcass (1) is equipped with a peripheral flange (4) at the ends thereof. The inventive tyre is reversible and sufficiently elastic to be turned over when the outer tread (2) has worn down, in order for the inner tread (7) to be used.</p> |
