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.

Abstract: By forming a ground contact edge side of lug grooves such that the groove depth becomes shallower in groove depth from the tire equatorial plane side toward the ground contact edge, and by setting an average angle of inclination formed between a tread face and a groove bottom to be not more than 5°, water expulsion is performed smoothly in the vicinity of the ground contact edge while securing the rigidity of land portions in the vicinity of the ground contact edge. This enables a high degree of both wet performance and dry performance to be achieved.
