Description

technical field

[0001] The present invention relates to a pneumatic tire including an annular bead core embedded in a bead portion and a carcass layer locked to the bead core. Pneumatic tires that achieve performance equal to or better than conventional ones while achieving weight reduction using composite cords. Background technique

[0002] A pneumatic tire generally includes a carcass layer stretched between a pair of bead portions. In addition, an annular bead core is embedded in the bead portion, and the carcass layer is wound around the bead core from the inner side of the tire to the outer side and locked to the bead core.

[0003] Conventionally, as the bead core of a pneumatic tire, a laminated bead in which one or more steel wires are continuously wound in layers along the tire circumferential direction, or a ring-shaped core made of steel wires has been used. A cable bead (English: cable bead) formed by helically winding side wires composed of other steel wires ...
