Abstract:
The present invention is a pneumatic tire in which a strand made by rubber-coating one bead wire is wound in the shape of an annulus and stacked in a plurality of rows in the axial direction of the annulus and in a plurality of stages in the radial direction thereof to make a bead core, which is embedded in a bead part of the tire, the tire being characterized in that the bead core comprises two rows in the axial direction of the annulus, a winding start end and winding finish end of the bead wire being positioned at an outermost stage in the radial direction in the respective rows where the winding start end and winding finish end are positioned, and the winding start end and/or winding finish end of the bead wire has a greater gap from an adjacent bead wire on an inner peripheral layer than the gap between other adjacent bead wires.
