摘要： Provided is a pneumatic tire having laminated reinforcement layers with organic fiber over a bead core, and in the layer, a rubber-coated organic fiber cord is tilted to the center line of the bead core in a transverse section and is spirally coiled, in which each organic fiber cord in an inner and outer adjacent reinforcement layers over the bead core extends such that an organic fiber cord in the inner reinforcement layer and an organic fiber cord in the outer reinforcement layer intersect each other relative to the center line of the bead core in the transverse section, in which in the inner reinforcement layer, the cord is coiled with space at least partially in a tire circumferential direction such that the cord does not overlap in the tire circumferential direction, and the outer reinforcement layer is arranged to cover at least a part of the space.

摘要： Provided is a pneumatic tire having laminated reinforcement layers with organic fiber over a polygonal cross-section bead core, and in the layer, a rubber-coated organic fiber cord is tilted to the center line of the bead core in a transverse section and is spirally coiled, in which each organic fiber cord in an inner and outer adjacent reinforcement layers over the bead core extends such that an organic fiber cord in the inner reinforcement layer and an organic fiber cord in the outer reinforcement layer intersect each other relative to the center line of the bead core in the transverse section, in which in the inner reinforcement layer, the cord is coiled with space at least partially in a tire circumferential direction such that the cord does not overlap in the tire circumferential direction, and the outer reinforcement layer is arranged to cover at least a part of the space.
