    Abstract: A tyre for motorcycles includes a carcass structure, a belt structure 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 structure. The belt structure is of the zero degree type and includes at least one reinforcing cord including a core made of non metal material, and a plurality of metal wires substantially parallel to one another and helically wound around the core with a predetermined winding pitch. The metal wires are in such a number as to not completely surround the core. In particular, the metal wires are arranged around the core so that, in any cross-section of the reinforcing cord, they are located at just an angular portion of an ideal circumference that circumscribes the core.

    Abstract: A reinforcing cord of the present invention is a reinforcing cord (10) for rubber reinforcement including a fiber core (11) and a plurality of strands (12) disposed around the fiber core (11). The fiber core (11) is formed of one or a plurality of highly elastic fibers having a tensile elastic modulus of at least 100 GPa. Each of the plurality of strands (12) is formed of a plurality of glass fibers that are primarily twisted, and the plurality of strands (12) are finally twisted to be disposed around the fiber core (11). The direction of the final twist of the plurality of strands is opposite to the direction of the primary twist in each of the plurality of strands (12). The number of final twists of the plurality of strands (12) is 1.0 to 3.0 times/25 mm, and a ratio of the number of primary twists in each of the plurality of strands (12) to the number of final twists of the plurality of strands (12) (the number of primary twists/the number of final twists) is in a range of 1.5 to 2.5.
