Abstract: A tyre for vehicle wheels comprises a support structure and a tread band arranged in a radially outer position with respect to the support structure. The support structure comprises a plurality of hybrid reinforcing cords (10). Each of the hybrid reinforcing cords (10) has at least two strands (20) twisted together with a predetermined twisting pitch. Each of said at least two strands (20) comprises at least one monofilament textile wire (21) and at least one multifilament textile yarn (22) comprising a plurality of textile filaments (22a). In any cross section of the hybrid reinforcing cord (10), said at least one monofilament textile wire (21) is at least partially embedded in the filaments (22a) of said at least one multifilament textile yarn (22).

Abstract: A tyre (1) for motorcycles comprises a carcass structure (2), a belt structure (10) applied in radially outer position with respect to the carcass structure (2), a tread band (11) applied in radially outer position with respect to the belt structure (10), wherein the carcass structure (2) comprises at least one carcass ply (3). The carcass ply (3) comprises a plurality of reinforcing cords (20) comprising a first end (21) and a second end (22) twisted together, wherein the first end (21) is a hybrid yarn (23) comprising a plurality of first filaments (24) mixed with a plurality of second filaments (25), wherein the filaments of the plurality of first filaments (24) are made from a single material having a first modulus and wherein the filaments of the plurality of second filaments (25) are made from a single material having a second modulus different from the first modulus. The second end (22) is a textile yarn (28) comprising a plurality of third filaments (29) made from at least one material having a third modulus.

Abstract: A tyre for vehicle wheels comprises a support structure and a tread band arranged in a radially outer position with respect to the support structure. The support structure comprises a plurality of hybrid reinforcing cords (10) each having a plurality of monofilament textile wires (20) twisted to at least one multifilament textile yarn (30). In any cross section of the hybrid reinforcing cord (10), at least one portion of at least one monofilament textile wire (20) of said plurality of monofilament textile wires (20) defines a first radially outer surface portion of the hybrid reinforcing cord (10) and at least one portion of said at least one multifilament textile yarn (30) defines a second radially outer surface portion of the hybrid reinforcing cord (10).
