Pneumatic tire

A pneumatic tire comprising a pair of bead portions, a carcass as a skeleton extending in a toroidal shape across the pair of bead portions, a belt including at least one slant belt layer, and a tread, the belt and the tread being sequentially disposed on a radially outer side of a crown portion of the carcass, wherein

• as seen in a cross section in the tire width direction when the tire is mounted on a prescribed rim,
• the belt has a flat shape in the tire width direction;
• an SWh/SH ratio is not less than 0.5, where SWh is the shortest distance between a line segment parallel to a rotation axis of the tire at the maximum width position of the tire and a line segment parallel to the rotation axis of the tire at a bead toe, and SH is a sectional height of the tire;
• a curvature of the carcass in the cross section in the tire width direction is the maximum on a path from an intersection (I2) between a line segment perpendicular to the rotation axis of the tire from a widthwise end of the narrowest slant belt layer and the carcass, to an intersection (I4) between a line segment parallel to the rotation axis of the tire at the maximum width position of the tire and the carcass;
• and
• a path length CSR1 of the carcass from an intersection (I1) between a line bisecting a radial distance CSH between the radially outermost end of the carcass and the radially outermost end of a bead core and extending parallel to the rotation axis of the tire, to the intersection (I2), is longer than a path length CSR2 of the carcass from the intersection (I1) to an intersection (I3) between a line connecting the radially outermost ends of both bead cores.
