ABSTRACT OF THE DISCLOSURE A tread-pattern for tires, particularly for large-size tires destined for high-speed vehicles that have a great load-capacity. The tread-pattern is charac- terized by the presence of a plurality of circumferential zig-zag grooves that divide the tread-band into longitudi- nal ribs and by means of a plurality of sipes that divide the central ribs into a circumferential succession of blocks which the sipe-profiles render mutually indented one into the other. The profile is a broken line constituted by three successive segments of which the initial and final ones con- stitute the extension of a portion of the zig-zag development of the longitudinal grooves, while the central one presents a greater circumferential development than the corresponding development between the end-points of the sipe. - 17 -
