Abstract
Tire tread including a pattern formed by at two ridges of mean width L, which include a plurality of incisions whose traces on the contact surface extend between two points of intersection A and B, the segment AB making an angle with the transverse direction of the tread at most equal to 40°, the tread wherein each incision, of mean width E, includes a succession of incision portions, some of said incision portions having, on any surface parallel to the contact surface in the new condition and located between said surface in the new condition and ⅔ of the maximum depth of the incision, traces that make an average angle β at most equal to 15° with the longitudinal direction of the tread, said portions having a total length Lt which is at least equal to one-fifth of the ridge width; and in that the incision portions whose traces make an average angle β are provided on their opposite walls with relief elements of amplitude K designed to cooperate with one another to block relative movements between one incision wall and the opposite wall, the amplitude K of said relief elements being between 4 and 10 times the mean width E of the incision.
