A tread (10) for a tire has at least three wide grooves (13,14,15,16) therein. At least two zigzag ribs (19,20,21) are bordered by said grooves and have block elements (22) nested in the reentrant angles of the ribs and separated therefrom by narrow grooves (23). The wide grooves (13,14,15,16) well remain open in a footprint of a tire while the narrow grooves (23) will close up in a footprint of a tire. Tire treads according to the invention may be provided as precured retread material, as part of a newly manufactured tire, or as part of a retreaded tire.
