Abstract
Tire tread comprising elongate block (3) of rubbery material and extending in a circumferential direction of the tire. Elongate block (3) comprises a ground contact surface (5) delimited first and second lateral walls (7,9). Elongate block (3) comprises a plurality of oblique cutouts (11a, 11b) that open onto either the first or second lateral wall s and extend as far as cutout ends (13a, 13b) which do not open onto said lateral walls (7, 9). The cutouts of the plurality of cutouts (11a, 11b) are distributed over the contact surface (5) of the block such that when a cutout (11a) reaches its cutout end (13a), another cutout (11b) starts out from a lateral wall (9), at a same circumferential level (N) on the elongate block (3). The cutouts (11a, 11b) are sipes.
