充气轮胎
摘要：
本发明提供一种不会降低直行行驶时各性能并提高旋转时的稳定性和排水性的充气轮胎。充气轮胎(1)向车辆的装配方向已被指定且具备左右非对称的胎面花纹，且胎面部的外侧区域的陆地比小于胎面部的内侧区域的陆地比。设置于胎面部(2)的宽主沟(3)由设置于外侧区域的外侧宽主沟(4)和设置于内侧区域(Ai)的内侧宽主沟(5)形成。外侧宽主沟(4)包括：在离轮胎赤道(C)隔开胎面接地宽度的5～15％的距离的位置上设置沟中心线的第一外侧宽主沟；在离轮胎赤道隔开胎面接地宽度的15～28％的距离的位置上设置沟中心线的第二外侧宽主沟。第一外侧宽主沟和第二外侧宽主沟的轮胎轴向两侧具备沿轮胎周向连续地延伸并未被横沟划分的肋条。
摘要（英）：

The present invention provides a pneumatic tire not reducing capacities in running and capable of improving stability and water discharge ability in rotation. A wide main groove (3) arranged on tyre face (2) is formed with external side wide main groove (4) arranged on external side zone and an internal side wide main groove (5) arranged on internal side zone (Ai). The external side wide main groove (4) comprises: a first external side main groove arranged on a position away from equatorial line (C) by tyre grounding width of 5-15% distance; a second external side main groove arranged on a position away from equatorial line by tyre grounding width of 15-28% distance; tyre shafts of the first external side main groove and the second external side main groove are provided with ribs not divided by grooves and continuously extending in circumferential direction of the tyre.
