    • A motorcycle tire suitable for running on a road having rain grooves formed on the surface, which has a first main groove circumferentially continuously formed in a central region of the tread portion and second main grooves formed at least one run of unitary groove portions at each side of and with space from the first main groove and having interrupted portions at intervals in the circumferential direction of the tire. The first main groove comprises a plurality of groove segments and a plurality of connecting groove segments, and the groove segments, which lie circumferentially alternately at one and the other of two regions of the tread portion divided and lying closely along the center line of the tread portion and lie parallel to the center line and circumferentially successively spaced, are connected by the connecting groove segments which extend across the center line and connect together the facing ends of each two adjacent groove segments. The ratio of the interrupted portions to the pitch of repetition of unitary groove portions of the second main grooves is from 20 to 50%.
    • 一种适用于在具有形成在所述表面上的具有雨槽的道路上行驶的摩托车轮胎,所述摩托车轮胎具有在所述胎面部的中心区域中周向连续形成的第一主槽和在每一侧形成至少一排整体槽部的第二主槽 并且具有来自第一主槽的空间,并且在轮胎的圆周方向上具有间隔的中断部分。 第一主槽包括多个槽段和多个连接槽段,以及沿着胎面部分的两个区域中的一个和另一个周向地交替地沿着胎面的中心线分开并且靠近胎面的中心线的槽段 部分并且平行于中心线并且周向地连续间隔开,并且通过延伸穿过中心线并连接在每个两个相邻槽段的相对端部的连接槽段连接。 第二主槽的单位槽部的中断部与重复间距的比例为20〜50%。
