Abstract
A tire includes a carcass, a belt structure, and a tread band. The belt structure includes at least two belt plies and at least one belt layer radially external to the belt plies. The at least one belt layer extends at least for an axial width of the at least two belt plies and includes at least one first elongated element and at least one second elongated element. The elongated elements form turns substantially oriented in a circumferential direction of the tire. The turns are alternately disposed along an axial development of the at least one belt layer. The at least one first elongated element is a hybrid cord including at least one high-elastic-modulus filament and at least one low-elastic-modulus filament that are twisted together. An elastic modulus of the at least one second elongated element is lower than an elastic modulus of the at least one first elongated element.
