Abstract: A tyre for vehicle wheels includes a tread band on which grooves are formed, which generally define a tread pattern of the tyre. At least one pitch is defined in the tread pattern. The pitch extends axially on the tread band. The total number of pitches formed on the tread band is greater than 110.

Abstract: An “all season” tyre (1) for cars and/or light transport vehicles is described, having a tread band (8) provided with a plurality of longitudinal channels and a plurality of grooves (6, 7, 11, 12, 13) and sipes (21, 22, 23, 24, 25) having a substantially transverse course, regularly arranged in the central ribs formed by the longitudinal channels and in the shoulder regions (L2, L3) over the whole tread band (8). The tread band (8) also has transverse notches resulting from joining a groove and a sipe having a transverse course, arranged consecutively to each other, and seamlessly extending substantially over the whole portion of the tyre containing them, i.e., the shoulder regions (L2, L3) or some of the central ribs (9, 10).

Abstract: A tyre for vehicle wheels includes a tread band having a first annular portion delimited by two circumferential channels. The first annular portion includes two annular grooves extending along respective zig-zag paths. Each of the two annular grooves is defined by a plurality of first parts inclined on one side with respect to a reference plane orthogonal to an equatorial plane of the tyre and by a plurality of second parts inclined with respect to the reference plane on the opposite side to the first parts. Each of the second parts is circumferentially interposed between two respective first parts. Each of the first parts is connected to a respective circumferential channel by a respective first transversal groove arranged at an intermediate portion of the first part and by a respective second transversal groove arranged at an end of the first part.

Abstract: A tyre includes at least one block on which at least one complex type sipe is obtained separating the block into two portions having a first surface and a second surface facing each other. The first surface is extended between a set of first and second longitudinal sections having, respectively, a first and a second radial profile, which are symmetrical to each other, each one comprising a coupling portion between the two block portions formed by a protrusion and a recess defined by three consecutive inclined lengths, the pattern of which is such that the ends of the coupling portion are offset from each other along a direction transverse to the longitudinal direction of the sipe.
