A pneumatic tire, having in a tread surface thereof a pair of circumferential grooves formed on respective sides of the tire equatorial plane in the middle, a rib-like central land portion row demarcated by the circumferential grooves, and a plurality of lateral grooves extending between the central land portion row and each tread end, comprises in each half region of the tread: a row of first intermediate blocks each having a circumferential length D2 and demarcated by the lateral grooves, the corresponding circumferential groove, and first longitudinal grooves; and a row of second intermediate blocks demarcated by the lateral grooves, the first longitudinal grooves, and second longitudinal grooves, wherein facing openings of the first/second longitudinal grooves adjacent in the tire circumferential direction are offset from each other, and provided that D1 represents a circumferential distance between adjacent ends of the adjacent first and second intermediate blocks, D1 ‰¤ D2/2. |
