Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tire with further improved braking performance and drainage characteristics on a wet road while maintaining functions on a snowy road.SOLUTION: In a lower part of a kerf 100 formed in a block of a tread, a tubular flow channel 120 is formed having a width larger than the width of a kerf opening 110. A connecting band 130 connects the kerf opening 110 and the flow channel 120. The kerf opening 110 is formed to have a zigzag wave along the tire circumferential direction in the tread block, and the zigzag wave is formed such that the amplitude decreases along the depth direction of the block.SELECTED DRAWING: Figure 3 【課題】雪道での機能を維持するとともに、濡れた路面で制動性能及び排水性を一層向上させたタイヤを提供する。【解決手段】トレッドのブロックに形成されたカーフ１００の下部にはカーフ入口部１１０の幅より広い管状の流路管部１２０が形成され、カーフ入口部１００と流路管部１２０とは連結孔帯１３０で連結され、カーフ入口部１１０はトレッドブロックのタイヤの円周方向に沿ってジグザグウェーブを成して形成され、ジグザグウェーブはブロックの深さ方向に沿っていきながら振幅が小さくなるよう形成される。【選択図】図３
