<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving tire strength.SOLUTION: A portion where a bead wire is wound at first time is positioned at a part separated from an apex of a hexagon by twice or more of radius of the bead wire. Among the parts of the bead wires positioned on a side extending to outside of a tire rotation axis direction, a part from the portion where the bead wire is wound at first time to one end part of the side extending to outside of the tire rotation axis direction is a first continuous part wound adjacently and continuously each other. A portion adjacent to outside of a tire radial direction to the first continuous part is a second continuous part continuously and adjacently wound from the part adjacent to the one end to the part adjacent to the portion wound at first time. A portion adjacent to the other end part side of the side extending to outside of the tire rotation axis direction with respect to the portion wound at first time is adjacent to the portion wound finally among the second continuous part and is wound next the portion wound finally among the second continuous part.</p> |
