PNEUMATIC TIRE

A pneumatic tire includes a tread development width TDW in a tread portion and a tire maximum width SW which satisfy 0.70≤TDW/SW≤0.75. A profile line forming an outer surface of a sidewall portion in a tire meridian cross-section includes at least three arcs having mutually different radii of curvature. In the profile line, a radius of curvature R of an arc from a first point to a second point, a radius of curvature R of an arc from the second point to a tire maximum width position, and a radius of curvature R of an arc forming a portion on an inner side in the tire radial direction from the tire maximum width position satisfy RRR A height SDH in the tire radial direction from a bead heel to the tire maximum width position and a tire cross-sectional height SH satisfy 0.47≤SDH/SH≤0.50.
