The present technology relates to a pneumatic tire in which a plurality of small blocks is delineated and formed by a plurality of rectilinear circumferential narrow grooves and a plurality of widthwise narrow grooves that communicate with the circumferential narrow grooves, and small block rows with the small blocks aligned along a tire circumferential direction are formed between adjacent circumferential narrow grooves. Each of the small blocks has a surface area differing from that of at least one small block that belongs to an adjacent small block row on at least one side with respect to a tire width direction and has an overlapping tire circumferential directional region. The small blocks have surface areas of no less than 20 mmand no more than 400 mm.
