Zusammenfassung:	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). Cette invention concerne un pneumatique pour roues de véhicule, comprenant une structure de support et une bande de roulement disposée dans une position radialement externe par rapport à la structure de support. La structure de support comprend une pluralité de câbles de renforcement hybrides (10). Chacun des câbles de renforcement hybrides (10) a au moins deux brins (20) torsadés avec un pas de torsadage prédéfini. Chacun desdits brins (20) comprend au moins un fil textile mono-filament (21) et au moins un fil textile multi-filament (22) comprenant une pluralité de filaments textiles (22a). Dans toute section transversale du câble de renforcement hybride (10), ledit/lesdits fil(s) textile(s) mono-filament (21) est/sont au moins partiellement intégré(s) dans les filaments (22a) dudit/desdits fil(s) textile(s) multi-filament (22).
