PROBLEM TO BE SOLVED: To provide a pneumatic tire that can exert excellent noise performance while maintaining steering stability.SOLUTION: In the pneumatic tire, a shoulder main groove 5 and a center main groove 6 are provided at a tread part 2 and thereby a middle land part 7 is partitioned. In the divided middle land parts 7 are provided a middle vertical sipe 10 and a plurality of middle lateral sipes 11. The middle lateral sipes 11 include a plurality of inner middle lateral sipes 12, one ends of which communicate with the center main groove 6 and the other ends of which terminate at the center main groove 6 side, not at the middle vertical sipe 10. The inner middle lateral sipes 12 include a first inner middle lateral sipe 15, at least part of which has a depth larger than the middle vertical sipe 10.SELECTED DRAWING: Figure 1 【課題】操縦安定性を維持しつつ優れたノイズ性能を発揮しうる空気入りタイヤを提供する。【解決手段】トレッド部２に、ショルダー主溝５とセンター主溝６とが設けられることにより、ミドル陸部７が区分された空気入りタイヤである。ミドル陸部７には、ミドル縦サイプ１０と、複数のミドル横サイプ１１とが設けられる。ミドル横サイプ１１は、一端がセンター主溝６に連通しかつ他端がミドル縦サイプ１０よりもセンター主溝６側で終端する複数の内側ミドル横サイプ１２を含む。内側ミドル横サイプ１２は、ミドル縦サイプ１０よりも大きい深さを少なくとも一部に有する第１内側ミドル横サイプ１５を含む。【選択図】図１
