A tread for a heavy truck tire is provided that has a shoulder rib (22) with a shoulder rib upper surface (24), and a sacrificial rib (26) with a sacrificial rib upper surface (28). The sacrificial rib (26) is located outboard from the shoulder rib (22) in the lateral direction and engages the shoulder rib (22) such that an interface is present at engagement of the sacrificial rib and the shoulder rib. The sacrificial rib upper surface (28) is located closer to the central axis in the radial direction than the shoulder rib upper surface (24) is located to the central axis in the radial direction. A plurality of decoupling sipes (32) in the shoulder rib (22) extend through the interface and into the sacrificial rib (26). The decoupling sipes (32) are spaced from one another in the circumferential direction such that immediately successive ones of the decoupling sipes (32) are not in engagement at the interface.
