A heavy truck tire tread is provided that has an outer surface and a circumferential groove (24) that extends in the circumferential direction completely around the tread. A rib (26) is present that has a rib element (28) that defines a portion of the circumferential groove (24) and has an upper surface (30) in the radial direction. The upper surface has a leading edge (32) and a tailing edge (34) in the circumferential direction. The leading edge (32) and the tailing edge (34) are at different distances to the central axis in the radial direction. A first micro sipe (40) extends into the rib and opens into the circumferential groove (24), and a second micro sipe (42) extends into the rib (26) and opens into the circumferential groove (24). The rib element (28) extends from the first micro sipe (40)) to the second micro sipe (42) in the circumferential direction.
