摘要： 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, wherein the belt structure is of the zero degree type and includes at least one reinforcing cord having an elongation at break smaller than about 3%; the cord includes a plurality of first metal wires twisted together so as to form a core of first metal wires and a plurality of second metal wires twisted together around said core; and the number and the diameter of the second metal wires are such that the second metal wires are not able to fully enclose the core.

摘要： A tyre includes a carcass structure including at least one carcass ply, a belt structure applied in a radially outer position with respect to the carcass structure, and a tread band applied in a radially outer position with respect to the belt structure. The belt structure includes two main belt layers and first and second reinforcing strips incorporating a plurality of reinforcing elements arranged substantially in the circumferential direction. The reinforcing elements include at least one high-elongation metal cord including a plurality of intertwined strands, and each strand includes a plurality of filaments. Each filament has a diameter not greater than 0.175 mm.

摘要： 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.
