1. A process for manufacturing a structural component of a tyre for vehicle wheels, comprising:
providing at least one elongated element comprising at least one metallic wire twisted together with at least one textile yarn;
removing the at least one textile yarn from the at least one elongated element to form a metallic reinforcing cord, wherein the at least one metallic wire extends in the metallic reinforcing cord along a helical path around a free space previously occupied by the at least one textile yarn; and
incorporating the metallic reinforcing cord in a piece of elastomeric material to make the structural component of the tyre, wherein the structural component is a carcass structure, a belt structure, a bead reinforcing structure, or a zero degrees belt layer of the tyre.
