Summary:To provide a tire that can enhance excellent wet performance and an excellent service life of the tire.SOLUTION: A tire 1 is provided with a plurality of blocks 5. At least one of the blocks 5 is provided with a sipe 10. The sipe 10 has an opening shape extending zigzag along a longitudinal direction of the sipe on a tread surface of the block 5. The sipe 10 extends periodically to the inside in a tire radial direction, while keeping an opening shape and repeatedly keeping amplitude in a longitudinal direction of the sipe. In a periodic pattern in the tire radial direction of the sipe 10, half wavelength of the pattern is 0.10 to 0.24 times of maximum depth of the sipe 10, and a slope angle θ of the half wavelength relative to total amplitude is 45 to 65°.SELECTED DRAWING: Figure 1 【課題】優れたウェット性能とタイヤ寿命とを向上し得るタイヤを提供する。【解決手段】複数のブロック5が設けられたタイヤ1である。ブロック5の少なくとも一つには、サイプ10が設けられている。サイプ10は、ブロック5の踏面をサイプ長手方向に沿ってジグザグ状にのびる開口形状を有している。サイプ10は、開口形状を維持しつつサイプ長手方向に振幅を繰り返しながらタイヤ半径方向内側に周期的にのびている。サイプ10のタイヤ半径方向の周期的模様において、その半波長がサイプ10の最大深さの0.10〜0.24倍であり、かつ、全振幅に対する半波長の勾配角度θが45〜65°である。【選択図】図1
