To provide a tire that can exert excellent noise performance, while maintaining wet performance.SOLUTION: A tire has a tread part. The tread part includes at least one circumferential groove continuously extending in a tire circumferential direction. In a groove bottom part 7d of a circumferential groove 7, are formed a plurality of protrusion parts 20 protruding in a tire radial direction. Each of the plurality of protrusion parts 20 is formed in a vertical-long shape which has a width in a tire axial direction and a length in the tire circumferential direction larger than the width. The plurality of protrusion parts 20 each include taper parts 23 whose widths gradually become smaller toward one side in the tire circumferential direction.SELECTED DRAWING: Figure 3 【課題】ウェット性能を維持しつつ、優れたノイズ性能を発揮し得るタイヤを提供する。【解決手段】トレッド部を有するタイヤである。トレッド部は、タイヤ周方向に連続して延びる少なくとも１本の周方向溝を含む。周方向溝７の溝底部７ｄには、タイヤ半径方向に突出する複数の突起部２０が形成されている。複数の突起部２０のそれぞれは、タイヤ軸方向の幅と、幅よりも大きいタイヤ周方向の長さとを有する縦長状である。複数の突起部２０のそれぞれは、幅がタイヤ周方向の一方側に向かって小さくなっているテーパ部２３を含む。【選択図】図３
