Abstract

A tread (12) for a heavy truck tire is provided that has a bottom surface (14), a shoulder rib (16), and a sacrificial rib (20) located outboard from the shoulder rib (16) in a width direction. A decoupling void (30) is located between the shoulder rib (16) and the sacrificial rib (20). A decoupling void sipe (32) is in the shoulder rib (16) and opens at the shoulder rib upper surface (18) and at the decoupling void (30). The decoupling void sipe (32) extends in the thickness direction and is closer to the bottom surface (14) than the decoupling void (30) in the thickness direction.
