PROBLEM TO BE SOLVED: To provide a pneumatic tire that is improved in abrasion resistance and quietness while maintaining drainage performance and traction performance.SOLUTION: The pneumatic tire has one or more land parts sandwiched between a plurality of circumferential main grooves 21, 22 and 23 provided at a tread surface 1. In the land part, a plurality of blocks 7 are formed of lateral grooves 42, both ends of which open to the plurality of main grooves. In the blocks are formed an inclining groove 43, one end of which opens to the main grooves and the other end of which terminates in the blocks, and which inclines and extends relative to a tire circumference direction. The inclining groove includes: a connection part 43a which connects to the circumferential main grooves; a wide part 43b which connects to the connection part; a narrow part 43c which connects to the wide part. The wide part and the narrow part are smaller in an inclination angle relative to the tire circumference direction than the connection part. In the blocks are formed sipes 52, one ends of which open to the connection part and the other ends of which open to the circumferential main grooves, where the sipes have bent parts.SELECTED DRAWING: Figure 1
【課題】排水性とトラクション性を維持しかつ、耐摩耗性と静粛性を向上させた空気入りタイヤを提供する。【解決手段】トレッド踏面1に、複数の周方向主溝21,22,23により挟まれた1以上の陸部を有し、前記陸部は、前記複数の主溝に両端が開口する横溝42により複数のブロック7が形成され、前記ブロックには、一端が前記主溝に開口し、他端が前記ブロック内で終端し、かつ、タイヤ周方向に対して傾斜して延在する傾斜溝43が形成されており、前記傾斜溝は、前記周方向主溝に連結する連結部43aと、前記連結部に連結する広幅部43bと、前記広幅部に連結する狭幅部43cとを含み、前記広幅部及び前記狭幅部は、前記連結部よりもタイヤ周方向に対する傾斜角が小さく、前記ブロックには、一端が前記連結部に開口し、他端が前記周方向主溝に開口するサイプ52が形成されており、前記サイプは、屈曲部を有している、ことを特徴とするものである。【選択図】図1
