摘要： Tyre for motorcycles, having a tread band includes a central annular portion symmetrically located astride an equatorial plane and two shoulder annular portions located on axially opposite sides with respect to the central annular portion. The tread band has a void-to-rubber ratio not greater than 25%. The central annular portion has an axial extension not greater than 65% of the axial development of the tread band and the central portion has at least one module circumferentially repeated. Each shoulder portion has an axial extension not greater than 40% of the axial development of the tread band and the module includes at least one pair of first grooves with substantially circumferential course, at least partially located on opposite sides with respect to the equatorial plane. The central annular portion has a void-to-rubber ratio not smaller than 10% and the module includes a plurality of second grooves located substantially transversally with respect to the equatorial plane. The substantially transverse second grooves define in each module together with said first grooves at least two tread band solid portions. The second grooves have at least one end spaced away from the adjacent first groove by a distance so as to form a substantially continuous tread portion adapted to connect at least two tread band solid portions.

摘要： A tyre for bicycle wheels, having a carcass structure, a belt layer arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt layer. The carcass structure has a carcass ply engaged with a pair of annular anchoring structures and including a plurality of reinforcing cords. The cords are inclined, with respect to an equatorial plane of the tyre, at a first angle between about 65° and about 90°. The belt layer has a reinforcing cord wound onto the carcass structure according to a winding direction oriented, with respect to the equatorial plane, at a second angle between about 0° and about 30°.

摘要： The present invention refers to a tyre for bicycle wheels comprising a tread band containing an anti-puncture system capable of having high resistance to the penetration of foreign bodies, simultaneously ensuring optimal handling performances. In particular the present invention regards a tyre for bicycle wheels comprising: a carcass structure; and—a tread band arranged in radially outer position with respect to the carcass structure; wherein said tread band is made by means of vulcanisation of a cross-linkable elastomeric composition comprising a reinforcement system constituted by modified silicate fibres of nanometric size and fibrillated polymer fibres of micrometric size.

摘要： A bicycle tyre (100), comprising a carcass structure (2) and a tread band (7) applied in a radially outer position with respect to the carcass structure (2). The tread band (7) comprises a crown portion (7a) extending astride of an equatorial plane (X) of the tyre (100) and having a predetermined radius of curvature (R1) and a pair of lateral portions (7b) arranged on axially opposite sides with respect to the crown portion (7a) and each having a second radius of curvature (R2) greater than said first radius of curvature (R1).
