- 1. A pneumatic tire comprising a carcass comprised of at least one carcass ply containing a steel cord(s) arranged at a cord angle of 70-90° with respect to an equatorial plane of the tire and toroidally extending between a pair of bead cores and wrapped around the bead core from an inside toward an outside in a radial direction to form a turnup portion, the improvement wherein a wrap part wrapping on a peripheral face of the bead core therealong is formed in the turnup portion of the carcass ply, wherein a displacement (d) of a point X changed from a deflated state to an inflated state is not more than 3 mm as measured at a section in the widthwise direction of the tire, wherein X is an arbitrary point on a carcass line located in a region of the bead portion outward from a contact region with a rim flange at the deflated state when the tire is mounted onto a recommended rim.
- 2. A pneumatic tire according to claim 1, wherein the tire satisfies a relation of R0<2H, preferably R0<H when a radius of curvature of the carcass line at the point X is R0 and a section height of the tire is H at the deflate state.
