    摘要： The invention relates to a tyre tread having a plurality of blocks (9) delimited by indentations, each block (9) having generally a parallelepipedal form and having a length (L) and a width (W), said width (W) being determined between a first side face (15a) of the block and a second side face (15b) of the block, said width (W) being smaller than said length (L), at least one block (9) from among the plurality of blocks comprises at least one cavity (17) located inside said block, said cavity extending mainly along the length (L) of said block. The tread comprises an incision (21) that extends mainly along the length (L) of said block, said incision opening out at the first lateral face (15a) of the block and said incision (21) opening out into the cavity (17), forming an opening (23), the length (Lo) of the opening which is determined along the length (L) of the block corresponding to at least 80% of the length (Lc) of the cavity which is determined along the length (L) of said block.

    摘要： The invention relates to a directional tire tread having a rolling surface (30), said tread being provided with a plurality of incisions (1) defined by walls (11, 12) located opposite each other, each of said walls leading into the rolling surface (30) to form an edge referred to as a leading edge (Aa) of a material element, corresponding to the edge making contact first, and an edge referred to as a trailing edge (Af) of the same material element, corresponding to the edge making contact after the leading edge, each incision (1) including at least one section (11, 101) defined by walls opposite each other making, with a direction perpendicular to the rolling surface passing through the intersection of the incision with the rolling surface, a mean negative angle α less than 55 degrees in absolute value, said tread being characterized in that said section (11, 101) of negative angle α leads into the rolling surface (30) through a widened end portion (2) defined by first and second surfaces (21, 22) facing opposite each other, the angles of the first surface (21) and second surface (22) being positive and not equal to each other.
