    摘要： Provided is a pneumatic tire which has both improved driving stability performance on a dry road surface and improved on-snow performance. A pneumatic tire has defined on the tread first lands and second lands. The first lands and the second lands are provided with recesses. The recesses include first recesses provided in first edges of the first lands, and also include second recesses provided in second edges of the second lands. The second recesses are provided so as not to intersect projection regions formed by projecting the first recesses onto the second edges in the axial direction of the tire.

    摘要： A pneumatic tire includes a tread portion including a pair of first main grooves, a pair of second main grooves, a first land portion between the first main grooves and a pair of second land portions each sectioned adjacent one of the pair of first main grooves and one of the pair of second main grooves. The first main grooves extend in a trapezoidal wave manner including inner elements, outer elements and inclined connecting elements. One of the second land portions is provided with a second lateral groove opened at one of the outer elements. The first land portion is provided with a recess having an opening at the one of the outer elements. In a tire circumferential direction, a center of the opening of the recess is located at a position different from a position of an extension line of a centerline of the second lateral groove.
