(EN) A heavy truck tire tread (2) having a longitudinal direction (LgD), a lateral direction (LtD), a tread depth direction (TdD), a ground contact surface (CS) and a pair of opposing tread shoulders (3, 4) spaced apart along the lateral direction is provided. The tread has a shoulder zone (SZ, SZ') adjacent each tread shoulder of the pair of opposing tread shoulders, the shoulder zones consisting of blocks (5, 6) adjacent to each other along the longitudinal direction and separated by lateral grooves (7, 8). A center zone (CZ) is defined between the shoulder zones. The center zone is decoupled from both shoulder zones by at least one longitudinal sipe (11) or groove, and each lateral groove (7) in a shoulder zone (SZ) is directly connected to an opposite lateral groove (8) in the opposite shoulder zone (SZ') by a lateral sipe (10) of the center rib.
(ZH) 提供一种重型卡车轮胎胎面(2)，其具有纵向方向(LgD)、横向方向(LtD)、胎面深度方向(TdD)、接地表面(CS)和沿着所述横向方向间隔开的一对相对的胎肩(3、4)。所述胎面具有邻近所述一对相对的胎肩中的每个胎肩的肩部区(SZ、SZ')，所述肩部区由花纹块(5、6)组成，所述花纹块沿着所述纵向方向彼此相邻并且间隔开横向凹槽(7、8)。在所述肩部区之间限定中心区(CZ)。所述中心区通过至少一个纵向沟槽(11)或凹槽与两个肩部区分离，并且肩部区(SZ)中的每个横向凹槽(7)通过中挡边的横向沟槽(10)直接连接到所述相对的肩部区(SZ')中的相对的横向凹槽(8)。
