Abstract
Tire tread comprising elongate block (3) of rubbery material extending in a circumferential direction (X) when the tread (1) is mounted on the tire. The elongate block (3) comprises a ground contact surface (5) delimited by first and second lateral walls (7,9), with a plurality of cutouts (11a, 11b) that open onto it. The cutouts (11a, 11b) extend in an oblique direction from the first lateral wall (7) in the direction of the second lateral wall (9) as far as cutout ends (13a, 13b). For at least one cutout (11a) that opens onto the first lateral wall (7), its end (13a) does not open onto the second lateral wall (9), and when this cutout (11a) reaches its cutout end (13a), another cutout (11b) starts out from the first lateral wall (7), at a same circumferential level (N) on the elongate block (3). The cutouts (11a, 11b) are sipes.
