PROBLEM TO BE SOLVED: To provide tread characteristics such as siping that affects tire performance.SOLUTION: This waveform sipe exists in a tire tread to extend, and is provided with: a radial-direction outside part 920 defined by a first waveform 930 that has first amplitude, a first width, and a first wavelength; and a radial-direction inside part 940 defined by a second waveform 950 that has second amplitude, a second width, and a second wavelength. The first wavelength may be less than 5% of a sipe lenth, or over 100% of the sipe length, or the second wavelength may be less than 5% of a sipe length, or over 100% of the sipe length, or the second amplitude may be over 50% of the first wavelength, or less than 10% of the first wavelength, or the second amplitude may be over 50% of the second wavelength, or less than 10% of the second wavelength.SELECTED DRAWING: Figure 9

    【課題】タイヤ性能に影響を及ぼす、サイプなど、トレッドの特性の提供。【解決手段】第1の振幅、第1の幅、および第1の波長を有する第1の波形930によって定義される径方向外側部分920と、第2の振幅、第2の幅、および第2の波長を有する第2の波形950によって定義される径方向内側部分940とを備える、タイヤトレッド中に延在するサイプ。第1の波長はサイプ長さの5%未満でよいか、もしくはサイプ長さの100%超でよいか、または第2の波長はサイプ長さの5%未満でよいか、もしくはサイプ長さの100%超でよいか、または第2の振幅は第1の波長の50%超でよいか、もしくは第1の波長の10%未満でよいか、または第2の振幅は第2の波長の50%超でよいか、もしくは第2の波長の10%未満でよい、波形サイプ。【選択図】図9
