Abstract: A pneumatic tire comprises a pair of bead portions, a sidewall portion extending from the bead portions outward in a radial direction of the tire, a tread portion connected to an outer side of the sidewall portion in the radial direction of the tire through a shoulder portion, and extension block groups in each of which a plurality of extension blocks to extending from at least the shoulder portion to the sidewall portion are arranged in a circumferential direction of the tire. The extension block group includes a first extension block whose cross section height from a tire equator point exceeds ½ of a tire cross section height, and a second extension block whose cross section height from the tire equator point is lower than the first extension block.

Abstract: A pneumatic tire has main grooves 1 extending in the tire circumferential direction, plural types of oblong hole groups 21 and 22 in the sidewall 3 of the main groove 1. The oblong hole groups have oblong holes 11 and 12 of the same shapes extending in the groove depth direction of the main groove 1 in the circumferential direction at intervals At least one of the widths w1 and w2, the depths d1 and d2, the spaces p1 and p2 of the oblong holes 11 and 12 differs from those of the other oblong hole groups by 0.1 mm or more, the circumferential lengths r1 and r2 of each oblong hole group is at least 5 mm, the circumferential length of respective oblong hole groups except the longest oblong hole group is not less than 10% of the circumferential length of the longest oblong hole group.

Abstract: A pneumatic tire provided with a plural of non-linear ridges 11 in a side wall region, wherein ridges 11 are composed of two or more non-linear ridge groups with different shapes and at least one ridge extends from a rim line R to H 80 which is a position corresponding to 0.8 H when tire height from a rim line to a tire maximum outside diameter is defined as H.

Abstract: The pneumatic tire 1 is provided with a land part 4 in a sidewall region S of a tire and a plurality of marks 11 protruding from a side wall surface, wherein at least one of the marks 11 partially overlaps with the land part 4 and an area of a portion 12 where a mark is overlapped is not greater than 40% with respect to the total area of a mark. In addition, the number of the marks 11 partially overlapping with the land part 4 is not greater than 60 % with respect to the total number of marks. Further, protruded height of the mark 11 from the side wall surface 21 is not greater than 3 mm.
