The present invention provides for a heavy truck tire tread (12) with a plurality of sipes (20) in the shoulder rib (18) that extend from the shoulder edge (14) to the shoulder groove (16). Each one of the sipes (20) has a bottom (28) with a teardrop (30) located at the bottom, and the bottom (28) does not extend the same depth in the thickness direction across the entire lateral length of the sipe (20). The bottom (28) at a middle of the sipe (20) extends for less of a depth in the thickness direction than does the bottom (28) at a shoulder edge (14) portion of the sipe (20) located outboard from the middle of the sipe (20) in the lateral direction. The bottom (28) at the middle of the sipe (20) extends for less of a depth in the thickness direction than does the bottom (28) at a shoulder groove (16) portion of the sipe (20) located inboard from the middle of the sipe (20) in the lateral direction.
