Tire tread (1) comprising a plurality of blocks (6), each block (6) comprising a leading face (61), a trailing face (62) and a contact face (60), the leading face (61) making a mean angleαA greater than 0 degrees, the trailing edge (62) making a mean angleαF greater than 0 degrees, the angleαA of the leading face (61) being greater than the angleαF of the trailing face, each block (6) comprises an incision (7) extending into the thickness of the block, this incision (7) being delimited by opposing faces provided with blocking means (71) for blocking the relative movements of one of the said faces with respect to the other face in at least one direction, this incision (7) dividing the contact face (60) of the block into two parts with substantially equal surface areas, this tread being characterized in that the incision (7) is inclined by a mean angleβ, measured with respect to the perpendicular to the contact face (60) in the same direction as the angleαA of the leading face and in that the volume of material contained between the leading face (61) and the incision (7) is less than the volume of material contained between the trailing face (62) and the same incision (7). |
