A bead portion of a pneumatic tire includes an annular bead structure in which a core part in which a bead core is covered with a resin, and a bead filler which is formed of a resin, are integrally formed. A plurality of concave portions and a plurality of convex portions are formed on a surface of the bead structure. Each of the concave portions is extended to and communicated with a tire radial direction outside end of the bead structure.

The tire has s bead structure including a bead core portion having a cord unit and a bead filler portion continuous to the bead core portion in the tire radial direction outside of the bead core portion and formed of a resin material. The bead filler portion has a tip portion which becomes thinner toward outside in the tire radial direction. The tip portion is positioned inside in the tire width direction inside than a straight line passing through a center in the width direction at an inside end in the tire radial direction of the bead core portion and passing through a center in the width direction at outside end in the tire radial direction of the bead core portion.

A bead portion of a run-flat tire includes a bead core portion having a bead cord, a first bead filler portion continuous to the bead core portion and provided outside in the tire radial direction of the bead core portion, and a second bead filler portion provided outside in the tire width direction of the first bead filler portion via a carcass ply. The second bead filler portion is formed of a resin material.

In a tire or a tire manufacturing method, a bead section includes a bead member formed by integrally molding a bead core, in which a resin material covers bead cords, and a bead filler made with a resin material covering the bead core, and around which a carcass ply, in the tire, is folded. In a cross-section along a tire widthwise direction and a tire radial direction of the bead member, the bead core is arranged by being shifted with respect to a width-directional center of the bead member.

A pneumatic tire having a bead filler molded over a bead bundle to form an over-molded bead. The bead bundle may include at least one bead wire. The bead bundle may be over-molded with the bead filler, forming an over-molded bead. The over-molded bead may be formed into a variety of shapes and may be constructed from a variety of materials.
