Tire

The present invention provides a tire capable of maintaining wet performance and exhibiting excellent noise performance. The tire has a tread portion (2). The tread portion (2) includes at least one circumferential groove (3) continuously extending in the circumferential direction of the tire. A plurality of protrusions (20) protruding in the tire radial direction are formed at the groove bottom of the circumferential groove (3). Each of the plurality of protrusions (20) has a lengthwise shape having a width in the tire axial direction and a length in the tire circumferential direction larger than the width. Each of the plurality of protrusions (20) includes a tapered portion (23) having a width that decreases toward one side in the tire circumferential direction. 本发明提供能够维持湿地性能并且发挥优异的噪声性能的轮胎。轮胎具有胎面部(2)。胎面部(2)包括沿轮胎周向连续地延伸的至少一条周向沟(3)。在周向沟(3)的沟底部形成有沿轮胎径向突出的多个突起部(20)。多个突起部(20)分别是具有轮胎轴向的宽度和比宽度大的轮胎周向的长度的纵长状。多个突起部(20)分别包括宽度随着朝向轮胎周向的一侧而变小的锥形部(23)。
