Abstract: Tire (1) comprising a directional tread (2) comprising a plurality of blocks (5) extending continuously along an overall curvature C from one of the edges (3) towards the centre (4) of said tread, all or some of the blocks (5) of the tread comprising a median sipe (10) of length S extending along a curvature C? substantially identical to the curvature C of the block, each block (5) comprising a central zone at an angle ?1 such that 35°??1?65°, an edge zone at an angle ?3 such that 0°??3?10°, and an intermediate zone between the central zone and the edge zone at an angle ?2 allowing continuity between the three zones, at least some of the blocks (5) being designed with a block chamfer (15) provided at the trailing edge in the intermediate zone and/or the edge zone.

Abstract: Tire comprising a directional tread that has two edges and a center. The tread comprises a plurality of blocks, each block extending continuously along an overall curvature C from one of the edges towards the center of the tread, forming a block central end provided with a central wall. Each block has a width WB and a length LB, this width increasing from the block central end in the direction of the edge. All or some of the blocks of the tread include a median sipe of length S and extending from the block central end along a curvature C? substantially identical to the curvature C of the block.

Abstract: Tire (1) comprising a directional tread (2) comprising a plurality of blocks (5) that are separated by grooves (9), all or some of the blocks (5) of the tread comprising a median sipe (10) of length S, each block comprising a central zone extending generally at an angle ?1 such that 35°??1?65° with respect to a transverse direction (Y), an edge zone extending generally at an angle ?3 such that 0°??3?10° with respect to the transverse direction (Y), and a joining zone between the central zone and the edge zone, the blocks (5) having a height H and, for two adjacent blocks, the width W of a groove (9) separating these two blocks in their central zone being determined such that H*0.6?W?H*0.8.
