Abstract: A tread comprises a central zone with a width of between 70% and 80% of the width W of the tread. The central zone comprises one or more circumferential bands, each being delimited by two grooves of a width greater than or equal to 2 mm, and each comprising a contact surface intended to come into contact with the ground and a plurality of transverse sipes distributed evenly in the circumferential direction. Each sipe has, on the contact surface, a width less than 2 mm so as to define a mean circumferential void ratio, which is between 0.5 times and 1.5 times the ratio between a mean thickness (E) of the circumferential band to a mean circumferential radius of curvature (Rc) of the said circumferential band. The sipes divide the circumferential band into a succession of blocks, each having two edge corners intersecting the contact surface of the circumferential band, at least one of the edge corners of said block extending radially by an inclined part forming a chamfer. This inclined part connects the edge corner to a lateral wall of the block so as to generate an offset in the circumferential direction between the said edge corner and the lateral wall of the block.

Abstract: Directional tire tread having a rolling surface, this tread being provided with a plurality of incisions bounded by mutually opposing walls, each of said walls entering the rolling surface in such a way as to form an edge called the leading edge of an element of material, corresponding to the edge that enters the contact patch first, and an edge called the trailing edge of the same element of material, corresponding to the edge that enters the contact patch after the leading edge, each incision comprising at least one segment bounded by mutually opposing walls that make, with a direction perpendicular to the rolling surface passing through the intersection of the incision with the rolling surface, a negative average angle α whose absolute value is less than 55°, this tread being characterized in that this segment of negative angle α exits the rolling surface via an enlarged end portion bounded by mutually opposing first and second faces, the angles of the first face and second face being positive and not equal to each other.
