Abstract: A car tyre having a tread that extends in axial direction for a width the tread including a central portion arranged across an equatorial plane, and two lateral portions opposed with respect to the central portion. The central portion is separated from the lateral portions of the tread by two circumferential grooves. The circumferential grooves have a width greater than about 6 mm. The central portion extends in axial direction for a width less than 20% of the width of the tread and includes a plurality of first sipes. Each lateral portion has a width greater than 30% of the width of the tread, and each lateral portion includes, furthermore, a plurality of transversal grooves. The transversal grooves of a lateral portion include at least a first inclined length that extends from a zone proximal to the respective circumferential grooves, moving away from the equatorial plane. The first inclined length has an inclination α≤60° with respect to equatorial plane. Each lateral portion includes a plurality of sipes. The density of the sipes decreases moving away from the equatorial plane.

Abstract: A tyre with a tread band having a plurality of blocks. The blocks include three-dimensional sipes extending in a direction incident to an advance direction of the tyre. Each sipe separates a block into a first block portion having a first surface facing the advance direction, and into a second block portion having a second surface facing the direction counter to the advance direction. Male/female couplings are provided between the first and the second block portions, the couplings formed by protuberances on the first surface and extending towards the second block portion, and by recesses on the second surface and extending away from the first block portion. The protuberances formed on the first surface have an apex that is spaced apart from the tread surface by no more than 40% of the depth of the three-dimensional sipe, measured at the apex.
