Abstract:
In a tire, in a cross-section of a core of a bead taken at a plane perpendicular to the circumferential direction, two or more rows of wire cross-sections aligned in the axial direction are stacked. When the radially innermost row is a first row and a row immediately outside the innermost row in the radial direction is a second row, the number of the cross-sections of the wire in the first row is less than that in the second row. An inner end of the second row is axially inward of a line drawn from an inner end of the first row and is perpendicular to a direction in which the first row extends. In the cross-section of the core taken at a plane perpendicular to the circumferential direction, an angle between a bottom side of the core and a bead base line is 2° to not greater than 9°.
