A tread (1) having a plurality of raised elements (5) provided with at least one first incision (10) and at least one second incision (20). Each first incision (10) comprises at least two non-planar parts (111) separated by an intermediate part (112). The non-planar parts exhibit a dual undulation, whereas the planar parts have a single undulation. Each second incision (20) comprises at least two non-planar parts (211) separated by an intermediate part (212). The non-planar parts (212) exhibit at least one undulation (2112) in the depth of the tread of maximum amplitude C, whereas each intermediate part (212) of the at least one second incision (20) has no deformation in relief. The first incisions (10) intersecting at least one second incision (20) to form at least one intersection and thus divide the raised element (5) in which they are made into several volume elements (55), each intersection being created between an intermediate part (112) of the at least one first incision (10) and an intermediate part (212) of the at least one second incision (20).
