Claim Text:
1. A pneumatic tire comprising: a polygonal block group is provided between two circumferential main grooves in a tread ground contact width, the polygonal block group comprising a plurality of polygonal blocks with five or more sides which are demarcated by thin grooves and arranged in at least two longitudinal rows and a plurality of lateral rows, the longitudinal rows being arranged so that the polygonal blocks included in adjacent longitudinal rows differ in phase from each other in a tire circumferential direction; side block rows are provided, one on each of the two sides in the tire width direction of the polygonal block group, the side block rows comprising a plurality of side blocks which are demarcated by the circumferential main grooves, lateral grooves, and the thin grooves and arranged in the tire circumferential direction; and a length in the tire circumferential direction of a first side block included in a first side block row provided on one side is larger than the length in the tire circumferential direction of a second side block included in a second side block row provided on the other side, wherein a side of the first side block and the second side block facing the circumferential main grooves has a linear shape, and a side of the first side block and the second side block facing the polygonal blocks has a complementary shape corresponding to the shape of the adjacent polygonal blocks, wherein a center in the tire width direction of the polygonal block group is offset from a tire equatorial plane, and a distance in the tire width direction between the first side block row and the tire equatorial plane is larger than the distance in the tire width direction between the second side block row and the tire equatorial plane.
