To provide a tire of which the wet performance, on-snow performance and noise performance can be made compatible with each other.SOLUTION: A tire 1 is provided which has a tread portion 2. A plurality of circumferential grooves 3 extending in the tire circumferential direction and a plurality of land portions 4 partitioned by the circumferential grooves 3 are formed in the tread portion 2. The circumferential grooves 3 include a first circumferential groove 3A and a second circumferential groove 3B adjacent to the first circumferential groove 3A and larger in a groove width than the first circumferential groove 3A. The land portions 4 include a first land portion 4A partitioned between the first circumferential groove 3A and the second circumferential groove 3B. A plurality of lateral grooves 5 extending in the tire axial direction and a plurality of lateral sipe 6 extending in the tire axial direction and smaller in a groove width than the lateral grooves 5 are provided in the first land portion 4A. A total value of the groove widths of the lateral grooves 5 and the lateral sipe 6 communicating with the second circumferential groove 3B is smaller than a total value of the groove widths of the lateral grooves 5 and the lateral sipe 6 communicating with the first circumferential groove 3A.SELECTED DRAWING: Figure 2

    【課題】 ウェット性能及び雪上性能とノイズ性能とを両立し得るタイヤを提供する。【解決手段】 トレッド部2を有するタイヤ1である。トレッド部2には、タイヤ周方向に延びる複数の周方向溝3と、周方向溝3により区分された複数の陸部4とが形成されている。周方向溝3は、第1周方向溝3Aと、第1周方向溝3Aに隣接しかつ第1周方向溝3Aよりも溝幅が大きい第2周方向溝3Bとを含んでいる。陸部4は、第1周方向溝3Aと第2周方向溝3Bとの間に区分された第1陸部4Aを含んでいる。第1陸部4Aには、タイヤ軸方向に延びる複数の横溝5と、タイヤ軸方向に延びかつ横溝5よりも溝幅が小さい複数の横サイプ6とが設けられている。第2周方向溝3Bに連通する横溝5及び横サイプ6の溝幅の合計値は、第1周方向溝3Aに連通する横溝5及び横サイプ6の溝幅の合計値よりも小さい。【選択図】 図2
