A tire pattern of a tread intended to be fitted on a tire and including a plurality of elements in relief intended to come into contact with the ground on which the tire fitted with such a tread travels. At least one element in relief having at least one lateral wall undercut relative to the running surface of the tread and provided with at least one incision which opens on to the surface wall of the element in relief and on to at least one undercut lateral wall. So as not to alter the rigidity of said element in relief, in a manner which may be disadvantageous for the performance of a tire fitted with this tread, provision is made that, for levels of wear of the tread between a first depth H1 and a second depth H2, each incision does not cut into the edges or ridges of said element in relief. Also, a mold equipped with molding elements for molding such a tread pattern.
