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.
