A tread for a heavy truck tire is provided having a shoulder rib (22) with a shoulder rib upper surface (24) and a sacrificial rib (26) with a sacrificial rib upper surface (28). The sacrificial rib (26) is located outside the shoulder rib (22) in the transverse direction and engages with the shoulder rib (22) such that there is an interface at the junction of the sacrificial rib and the shoulder rib. The sacrificial rib upper surface (28) is closer to the central axis in the radial direction than the shoulder rib upper surface (24) in the radial direction. A plurality of decoupling rills (32) in the shoulder rib (22) extend through the interface and into the sacrificial rib (26). The decoupling rills (32) are spaced apart from each other in the circumferential direction such that immediately consecutive ones of the decoupling rills (32) do not engage at the interface.
提供了一种用于重型卡车轮胎的胎面,该胎面具有带有肩肋上表面(24)的肩肋(22)和带有牺牲肋上表面(28)的牺牲肋(26)。该牺牲肋(26)位于该肩肋(22)在横向方向上的外侧并且与该肩肋(22)接合,使得在该牺牲肋和该肩肋的接合处存在界面。该牺牲肋上表面(28)在径向方向上比该肩肋上表面(24)在该径向方向上更靠近中心轴线。该肩肋(22)中的多个解耦细沟(32)延伸穿过该界面并进入该牺牲肋(26)。这些解耦细沟(32)在周向方向上彼此间隔开,使得这些解耦细沟(32)中的紧接连续的解耦细沟在该界面处不接合。
