<p>Tire provided with a tread surface and lateral faces intersecting at two corner edges to determine a total width of tread between the said two corner edges, provided with grooves of depth H opening onto the tread surface and delimited by faces of material which are distant by at least a width equal to 2 mm, a plurality of grooves on at least one of the opposing faces that delimit them with at least one profiled protrusion delimited by a radially external surface and by a radially internal surface, the radially external surface being closer to the tread surface than the radially internal surface, meeting at those points of the protrusion that are furthest away in the direction of the groove, each of these radially internal and external surfaces of each protrusion has, in a plane of section parallel to the faces delimiting the groove, a profile of length greater than the length of the profile of the radially internal surface.</p> |
