A heavy truck tire tread that has a rib is provided. A sipe is in the rib that extends from a first lateral surface to a second lateral surface. A first end of a teardrop is located at the first lateral surface, and a second end at the second lateral surface. 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.
