Abstract

Tyre provided with a tread (1) having a tread surface (10) intended to come into contact with the road and lateral faces intersecting the tread surface at two corner edges to determine a total width of tread between the said two corner edges, this tread being 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 (2) being provided on at least one of the opposing faces that delimit them with at least one profiled protrusion (6), this profiled protrusion being delimited by a radially external surface (31-e) and by a radially internal surface (31-i), the radially external surface being closer to the tread surface (10) than the radially internal surface, these external and internal surfaces meeting at those points (Al, A2)of the protrusion that are furthest away in the direction of the groove, this tread being such that 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 such that the length of the profile of the radially external surface (31-e) is greater than the length of the profile of the radially internal surface (31-i)
