摘要：
胎面花纹具备：向接地端(E1，E2)开口的胎肩横槽(12A，12B)，具有两端的中央横槽(14)，所述中央横槽(14)的端部，将所述胎肩横槽(12A，12B)的轮胎宽度方向的内侧的端交替地连接而形成为波形状的周向主槽(11A，11B)，和由所述中央横槽(14)与所述一对周向主槽(11A，11B)划分出的中央块(20)。周向主槽(11A，11B)的槽宽比胎肩横槽(12A，12B)的槽宽窄。中央横槽(14)相对于轮胎周向以及轮胎宽度方向倾斜，在中央横槽(14)，具有向轮胎周向的互相不同的方向突出的第3槽弯曲部(14a)以及第4槽弯曲部(14b)。
摘要（英）：

A tread pattern is provided with: shoulder lug grooves open at ground contact ends; center lug grooves each having opposite ends; circumferential primary grooves each formed in a wavy shape by connecting ends of the center lug grooves and the inner ends of the shoulder lug grooves in the width direction of the tire; and center blocks defined by the center lug grooves and the pair of circumferential primary grooves. The width of the circumferential primary grooves is smaller than the width of the shoulder lug grooves. The center lug grooves are tilted relative to both the circumferential direction and the width direction of the tire and each have a third groove turning portion and a fourth groove turning portion which protrude in the different directions in the circumferential direction of the tire.
