Abstract

Provided is a pneumatic tire which is provided with a carcass ply having a low turn-up structure, the pneumatic tire being configured so as to minimize strain near the turn-up ends of a carcass ply. A pneumatic tire (10) is configured so that a carcass ply (14) has body sections (14A) and turn-up sections (14B) and so that the turn-up ends (14C) of the turn-up sections (14B) are located on the outside, in the radial direction of the tire, of a bead base line (BL) at a position in the range of 15 to 28% of the cross-sectional height (SH) of the tire. The turn-up sections (14B) each have: a first region (A1) which extends from the inside toward the outside in the radial direction of the tire so as to gradually approach the body section (14A); a second region (A2) which is provided within the angle formed by a straight line (L1) passing through the center (O) of curvature of the rim flange (18) of a regular rim in an axial cross-section of the tire and extending inward in the axial direction of the tire so as to be parallel to the rotation axis of the tire, and by a straight line (L2) passing through the center (O) of curvature and extends inward in the tire width direction and outward in the radial direction of the tire at an angle of 45º, the second region (A2) extending along the body section (14A) so as to be close to or in contact with the body section (14A); and a third region (A3) which gradually extends away from the body section (14A).
