A tire for a two-wheeled vehicle includes a carcass of toric form having a high transverse curvature, a tread band, and a circumferentially-inextensible belt structure. The belt structure is interposed between the carcass and the tread band, and includes reinforcing elements. Relative to an equatorial plane of the tire, the reinforcing elements may be randomly oriented, substantially oriented in an axial direction, or substantially oriented in an inclined direction. The belt structure further includes a radially-external layer provided with a plurality of cord coils disposed at a substantially-zero angle relative to the equatorial plane of the tire. The cord coils are positioned in axial side-by-side relationship and extend from one axial extremity of the belt structure to an opposite axial extremity. A density of the cord coils grows from the equatorial plane of the tire to the axial extremities of the belt structure.
A tire for two-wheeled vehicles comprising a carcass of toric form having a high transverse curvature and provided with a central crown and two sidewalls terminating in a pair of beads for anchoring to a corresponding mounting rim, a tread band located on said crown and having a curvature ratio at least as high as 0.3 and a circumferentially-inextensible belt structure disposed between said carcass and tread band, in which that said belt structure at a radially external position is comprised of a layer of cord coils substantially disposed at a zero angle to the equatorial plane of the tire.
