Abstract:
A high transverse-curvature tire for two-wheeled vehicles, comprising:a carcass structure including at least two superimposed plies provided with reinforcing cords; a belt structure coaxially extending around the carcass structure, including a radially-outer layer and a radially-inner layer; and a tread coaxially extending around the belt structure; wherein the reinforcing cords of each ply of the at least two superimposed plies are essentially parallel to other reinforcing cords of that ply and are oriented along directions inclined with respect to an equatorial plane of the tire, wherein the reinforcing cords of at least two adjacent superimposed plies are oriented in opposite directions with respect to the equatorial plane of the tire, wherein the carcass structure further comprises at least one first sheet, located between the at least two superimposed plies, made of a first elastomeric material incorporating fibrous reinforcing fillers suitable to increase stretchability properties of the at least one first sheet without substantially altering adhesion properties of the at least one first sheet, wherein the radially-outer layer includes a plurality of circumferential coils, axially arranged side-by-side, of at least one inextensible cord circumferentially wound at a substantially-null angle with respect to the equatorial plane of the tire, and wherein the radially-inner layer comprises at least one second sheet made of a second elastomeric material incorporating fibrous reinforcing fillers suitable to increase stretchability properties of the at least one second sheet without substantially altering adhesion properties of the at least one second sheet.
