A tyre (100) for vehicle wheels comprises a carcass structure (101), a crossed belt structure (106) arranged in a radially outer position with respect to the carcass structure (101), at least one zero degrees reinforcing layer (106c) arranged in a radially outer position with respect to the crossed belt structure (106) and a tread band (10) arranged in radially outer position with respect to the zero degrees reinforcing layer (106c). The crossed belt structure comprises a first belt layer (106a) and at least one second belt layer (106b) arranged in a radially outer position with respect to the first belt layer (106a). At least one of the belt layers (106a, 106b) comprises a plurality of hybrid reinforcing cords (10) each having a core (11) made of a high modulus textile material and extending along a predetermined longitudinal direction (A) and a plurality of metallic wires (12) substantially parallel to one another and helically wound around the core (11) with a predetermined winding pitch (P). The metallic wires (12) are arranged around the core (11) so that, in any cross section of the hybrid reinforcing cord (10), they are located at only one angular portion of an ideal circumference (C) that circumscribes the core (11). The zero degrees reinforcing layer (106c) includes a plurality of non-hybrid reinforcing cords (10c).
