Abstract: A winter tyre is described having a tread band wherein a plurality of blocks configured to obtain optimal performance both on snow-covered roads and on dry and wet roads in specific conditions of use (in particular during acceleration, braking or cornering with high power vehicles). Each of the aforementioned blocks has at least one sipe that defines two adjacent block portions in the respective block, each block portion having a respective surface facing the sipe. The surface has a radially outer portion having a profile which is substantially undulating, a radially inner portion also having a profile which is substantially undulating and an intermediate portion arranged between the radially outer portion and the radially inner portion and having a profile which is substantially rectilinear.

Abstract: A tyre (1) for vehicle wheels comprises a tread band (2) on which a radially external tread surface (3) and a tread pattern are defined, and in which the following are defined: —a central region (5) of the tread band, extending circumferentially about an equatorial plane (X) of the tyre over a width equal to at least 30% of an effective width (L) of the tread band; —a first and a second shoulder region (6, 7) extending, respectively, on opposite sides of the central region, in an axially outer position of the tread band, each over a width equal to at least 20% of an effective width (L) of the tread band; the tread pattern, on each of the first and second shoulder regions and the central region, comprises a respective plurality of transverse grooves (20; 30; 40; 50) comprising a bottom (23; 33; 43; 53) and a pair of lateral walls (24, 25; 34, 35; 44, 45; 54, 55) facing one another. These lateral walls extend from the bottom towards the tread surface with a first inclination relative to a radial direction, and are joined, over at least a portion of their extent, to the tread surface by respective chamfers (26, 27; 36, 37; 46, 47; 56, 57), having a second inclination relative to the radial direction which is greater than the first inclination.
