PROBLEM TO BE SOLVED: To provide a pneumatic tire, wherein the durability of the side section is increased by effectively suppressing the generation of a surface distortion of the side section by optimizing the side flex zone, and at the same time, the riding property is increased, and the oblateness thereof is 40% or less. SOLUTION: This tire 1 is equipped with: a bead core 2; a bead section 4 in which a reinforcing rubber 3 is embedded; a belt 12 comprising tilted belt layers 11a and 11b on the outer peripheral side of the crown section 10 of a carcass 9; and a belt reinforcing layer 14, and the oblateness of the tire 1 is 40% or lower. In this case, for the belt 12, the carcass 9 which extends under a toroidal shape is arranged extending to respective sections of a side wall section 5 and a tread section 6. The reinforcing rubber 3 is constituted of a soft rubber of which the rubber hardness is 80 or lower. A skin rubber 15 constituting the side wall section 5 is formed in such a manner that the thickness t is 3.5 mm or smaller at a tire maximum width position P. A distance L when the side flex zone 18 is measured in the tire diametrical direction is set to be 30% or larger of a tire cross sectional height SH. COPYRIGHT: (C)2005,JPO&NCIPI
