To improve drainage, ice and snow, and hydroplaning resistance while maintaining steering stability.SOLUTION: A cut 29 is formed in a bridging body 26a provided on a sipe groove 23 and both side walls of the cut 29 are closely attached to each other. Thereby, the bridging body 26a normally functions as an integral body, easily reduces the tilting level of a block 22 upon grounding, and improves drainage while maintaining the steering stability. Further, when the cut 29 is partially opened due to tilting of the block 22 upon grounding, a gap is formed between the side walls of the cut 29, and water flows smoothly between the compartments 30 on both sides of the bridging body 26a.SELECTED DRAWING: Figure 4

    【課題】操縦安定性を維持しながら排水性、氷雪性、耐ハイドロプレーニング性を向上させる。【解決手段】サイプ溝23に設けられた橋渡し体26aに切れ目29を形成し、該切れ目29の両側壁同士を密着させたので、該橋渡し体26aは通常は一体物として機能し、接地時におけるブロック22の倒れ込み量を容易に低減させ、操縦安定性を維持しながら排水性等を向上させることができる。また、接地時にブロック22が倒れ込むことで切れ目29が部分的に開くと、該切れ目29の側壁間に間隙が生じ、橋渡し体26aの両側の区画室30間で水が円滑に流れる。【選択図】図4
