PROBLEM TO BE SOLVED: To provide a pneumatic tire reducing rolling resistance by suppressing deformation of a tread part. SOLUTION: This pneumatic tire includes the tread part 1, a pair of sidewall parts 2, a pair of bead parts 3, a carcass 5, and a belt 6 arranged on an outer peripheral side in a crown region of the carcass 5 and formed by one or more inclined belt layers constituted of cords extending in a direction inclined to a tire equatorial plane. The pneumatic tire includes a portion 10 where a radius of curvature of the carcass 5 becomes minimum and a portion where rubber thickness from a body part 5a of the carcass 5 up to a tire outside surface becomes minimum, located between a width direction end edge of a narrowest inclined belt layer and a tire maximum width position in a tire meridian cross section in an internal pressure non-loaded state with the tire fitted to an applied rim.
