PROBLEM TO BE SOLVED: To provide a pneumatic tire for an automatic two-wheeler, which is improved in traction performance.SOLUTION: A pneumatic tire for an automatic two-wheeler comprises: a plurality of blocks arranged on a tread surface; and a wide block extending over at least an intermediate region and having a tire widthwise length larger than the tire circumferential length. At least one recess is formed in the outer side or inner side of the tire widthwise direction from the tire widthwise center of said wide block. Relational expressions of 1.5≤W/L≤5.5 and 0.2≤W/T≤0.4, if, in the expansion view of said tread surface, the tire peripheral direction length of said wide block is designated by L, if the tire width direction length of said wide block is designated by W, and if the width of said tread surface is designated by T.SELECTED DRAWING: Figure 2
