Tread for a tire provided with a running surface intended to come into contact with the roadway when running, this tread comprising a plurality of blocks of mean axis XX' intersecting the running surface of the tread, each block, including a side wall that makes a full circuit of the block about the axis XX&#x2032;. This side wall intersects the running surface at an edge with a closed geometric outline, this edge delimiting a contact surface via which the block makes contact with the roadway. The side wall of the block and the opposite wall delimit an incision, the blocks being provided on their lateral surface with at least one notch having a depth measured perpendicular to the lateral surface of the block and a width measured parallel to the lateral face of the block, the at least one notch at least partially making a circuit of the block about the axis XX&#x2032;, that is to say at least over 180 degrees.
