Abstract:
A high transverse-curvature motor-bike tire, comprising:a carcass structure including at least one ply provided with reinforcing cords essentially parallel to one another and oriented along directions inclined with respect to an equatorial plane of the tire; a belt structure coaxially extending around the carcass structure and including a radially inner layer comprising at least one strip made of an elastomeric material incorporating a plurality of reinforcing cords essentially parallel to one another and oriented along directions inclined with respect to the equatorial plane of the tire; and a tread coaxially extending around the belt structure; wherein the belt structure further comprises a radially outer layer including a plurality of circumferential coils, axially arranged side-by-side, of at least one circumferentially inextensible cord wound at a substantially null angle with respect to the equatorial plane of the tire according to a winding direction adapted to compression-stress, at least during initial winding, elastomeric material portions interposed between consecutive reinforcing cords incorporated in the at least one strip of the radially inner layer.
