    Abstract: 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.

    Abstract translation: 具有胎面带的摩托车轮胎包括跨越赤道平面对称定位的中心环形部分和位于相对于中心环形部分的轴向相对侧上的两个肩部环形部分。 胎面带的空隙与橡胶比不大于25％。 中心环形部分具有不大于胎面带的轴向展开的65％的轴向延伸，并且中心部分具有周向重复的至少一个模块。 每个肩部具有不大于胎面带的轴向展开的40％的轴向延伸，并且该模块包括至少一对基本上圆周方向的至少部分地相对于赤道平面位于相对侧上的第一槽。 中心环形部分具有不小于10％的空隙与橡胶比，并且模块包括相对于赤道平面大致横向定位的多个第二槽。 基本上横向的第二凹槽在每个模块中与所述第一凹槽一起限定至少两个胎面带固体部分。 第二凹槽具有与相邻的第一凹槽隔开一段距离的至少一个端部，以形成适于连接至少两个胎面带固体部分的基本上连续的胎面部分。

    Abstract: 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°.

    Abstract: 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).

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.
