Abstract
A pneumatic tire comprises a bead core disposed in each of a pair of bead portions and a carcass ply turned up around the bead cores, wherein the bead cores are provided in the radially inner surface with a swell having a radius of curvature in the range of from 0.35 to 2.0 times the width of the bead core. The swell preferably extends all over the width of the bead core whereby no rubber layer is formed between the carcass ply and the radially inner surface of the bead core, and the contact pressure between the tire and rim is optimized.
