Abstract: A tyre for vehicle wheels comprising a tread band (2), upon which there are defined a plurality of first transverse grooves (30) and a plurality of second transverse grooves (60) slanted in a discordant manner with respect to the first transverse grooves (30). Each first transverse groove (30) comprises a first portion (33) slanted relative to said circumferential direction by a first angle (A), and a second portion (34) extending into first portion (33) is slanted relative to said circumferential direction by a second angle (B) smaller than the first angle (A). Each second transverse groove (60) comprises a first portion (62) slanted relative to the circumferential direction by a third angle (C), a second portion (63) extending from the first portion (62) and slanted relative to the circumferential direction by a fourth angle (D) smaller or equal to a third angle (C) and ending in said second portion (34) of said first transverse grooves (30), as well as a third portion (64) extending from the second portion (34) and parallel to the latter. There are identified a first group of second transverse grooves (60), comprising at most 20% of the second transverse grooves, wherein the third portion (64) is substantially aligned with the second portion (63) and a second group, is complementary to the first group, wherein the third portion (64) is not aligned relative to the second portion (63).

Abstract: A tyre for vehicle wheels comprises a tread band (2) having a tread pattern in which there are defined a central region (5) extending circumferentially and symmetrically across an equatorial plane (X) of the tyre over a width equal to about 60% of an effective width (L) of the tread band, and a first and a second shoulder region (6, 7) which extend at the axially opposing sides of the central region, respectively. The tread band comprises a plurality of main grooves (10) which extend from the central region (5), through the first or alternatively the second shoulder region (6, 7), in order to open at a lateral edge (8, 9) of the tread band, and at least one plurality of secondary grooves (20, 21) which extend in a substantially circumferential direction between consecutive pairs of main grooves (10). The main grooves are arranged in such a manner that any radial plane (R, S) intersects at the central region (5) with at least four main grooves (10).

Abstract: A tyre (1) comprises: a tread band (2) on which is defined a radially outer tread surface (3), a first plurality of blocks (6a, 6b) provided on the tread band, - at least a first sipe (10) of the restrained type extending on at least one block of the first plurality in a substantially axial direction (X) defined on the tread band. The first sipe is configured so as to define, between a first (8) and a second block portion (9) divided by the first sipe, at least two separate and distinct couplings (11) of the male/female type such as to prevent the mutual displacement of the block portions in any direction (A) which, at said block, is substantially tangential to the tread surface, and such as to permit mutual displacement of the block portions in a direction incident to the tread surface. In addition, the first sipe does not intersect any other sipe of the restrained type within the block.
