Heavy truck tire tread with rib element to manage irregular wear

A heavy truck tire tread, comprising:

• a circumferential direction that extends about a central axis, a lateral direction that extends parallel to the central axis, and a radial direction that is perpendicular to the central axis, wherein the tread has an outer surface;
• a circumferential groove that extends in the circumferential direction completely around the tread;
• a rib that has a rib element that defines a portion of the circumferential groove, wherein the rib element has an upper surface in the radial direction, wherein the upper surface has a leading edge and a tailing edge in the circumferential direction, wherein the leading edge and the tailing edge are at different distances to the central axis in the radial direction, wherein the outer surface of the tread at a portion of the rib that is adjacent the upper surface of the rib element in the lateral direction is located at a same distance from the central axis in the radial direction about the circumferential direction;
• a first micro sipe that extends into the rib and that opens into the circumferential groove;
• a second micro sipe that extends into the rib and that opens into the circumferential groove;
• wherein the rib element extends from the first micro sipe to the second micro sipe in the circumferential direction.
