Abstract:
1. A tread for a tire, the tread having a thickness and provided with a running surface intended to come into contact with the roadway when running, this tread comprising a plurality of rubber blocks, wherein each rubber block comprises a mean axis XX′ intersecting the running surface of the tread, a height at least equal to the thickness of the tread, and a side wall, wherein the sidewall: makes a full circuit of the block about the axis XX′; intersects the running surface of the tread at an edge which encloses a geometric outline of the block on the running surface, and which delimits a contact surface via which the block makes contact with the roadway; connects, at its base inside the tread, to a wall opposite, such that the side wall of the block and the wall opposite delimit an incision having a mean width; has a lateral surface with at least one notch having a depth measured perpendicular to the lateral surface of the sidewall and a width measured parallel to the lateral surface of the sidewall, wherein the at least one notch making a full circuit of the block about the axis XX′, that is to say at least over 360 degrees, and is situated a distance from the contact surface of the block that is between 70% and 80% of the height H of the block.
