A tire tread comprising a plurality of grooves opening on to a running surface, each groove having an average orientation and being defined by facing walls, these walls being connected together by a groove bottom, each groove being defined geometrically by a transverse profile obtained by intersecting said groove by a section plane substantially transverse to the average direction of the groove, the transverse profile of a plurality of grooves having variable curvatures, the variation of said curvatures in the section plane being mathematically continuous. A tire provided with such a tread.
