The invention concerns a tread band for a tyre, said tread band (1) comprising two sides (3) with a predetermined distance D between these two sides (3) and a centre (5). Indeed the tread band has a plurality of blocks (7), each block extending continuously in a curved manner to one side (3) of the tread band towards the centre (5) of this tread band with no groove separating this block in different parts, the block following a certain curvature C. All or part of the blocks of the plurality of blocks comprises a main sipe (9) extending in the block (7) and following the same curvature C, this sipe separating the block in two ½ parts (7a, 7b). |
