Abstract:
Provided is a tire 1 in which a point Al is defined as a point on a side profile at the same position in a tire radial direction as a radially outer end section of a bead core 11, 11; a distance Hl is defined as the distance in the tire radial direction from a maximum tire width position Ac to the point Al; a point Al' is defined as a point on the side profile at the position in the radial direction at 70[%] of the distance Hl from the maximum tire width position Ac; and a point Am is defined as a point on the side profile at the position in the radial direction at 35[%] of the distance Hl from the maximum tire width position Ac. In the case of the foregoing definitions, the radius of curvature RO [mm] of a circular arc passing through the maximum tire width position Ac, the point Al', and the point Am when the tire is mounted on a regulation rim, is subjected to a regulation internal pressure, and is put in an unloaded state, is in the range 0.20 ≤ RO / SH ≤ 1.20, with respect to the cross-sectional height SH [mm] of the tire.
