A heavy truck tire tread that has a shoulder rib and shoulder groove is provided. A sipe is in the shoulder rib that extends from the shoulder groove to the lateral outer surface. A first end of a teardrop of the sipe is located at the lateral outer surface, and a second end at the shoulder groove. A middle section of the teardrop is located between the first and second ends in the lateral direction. A first transition is located between the first end and the middle section, and a second transition is located between the second end and the middle section and they both extend in the lateral and thickness directions. The entire middle section is farther from the upper surface in the thickness direction than any portion of the first or second ends are to the upper surface in the thickness direction.
