Claims

[Claims for Utility Model Registration] A carcass ply of a metal cord extending from one bead portion to the other bead portion and having both ends folded and wound around an annular bead core from the inside to the outside; In a pneumatic tire having a bead reinforcing layer of metal cord that covers and wraps the outside of the folded part, the bead part is installed on the rim of a wheel: The bead part is surrounded by the carcass ply and the ply winding part. A hard rubber having a wedge-shaped cross section whose wall thickness gradually decreases toward the outside in the tire radial direction is filled in the bead portion of the tire, and the outer end of the hard rubber is located at a position further outward in the tire radial direction than the winding end of the carcass ply. On the other hand, the rolled-up end of the carcass ply is arranged in the soft rubber approximately in the thickness center of the maximum wall thickness part of the tire bead; The reinforcing layer is placed at a radially inward position, and the inner rolled end of the reinforcing layer is located at a position radially more inward than the rolled up end of the reinforcing layer and at a height near the upper end height of the rim flange of the wheel. A pneumatic tire characterized by being arranged at a position radially inward of the flange from the upper end of the flange.
