Each block is at least partially delimited by a groove which defines a flank of the block. The flank is joined to a tread surface portion. The tread surface portion is defined on the block in the region of an edge of the block. There are, on a portion of the edge, a plurality of consecutive recesses and, in the region of at least two of these recesses, there is a respective block portion which defines a protrusion. The protrusion projects from the flank of the block towards the inner side of the groove and extends as far as a bottom of the groove.
