Abstract
Tire including: a tread; a pair of sidewalls extending substantially inward radially from ends of the tread; a pair of beads positioned substantially radially inwardly of the sidewalls; and a clinch portion extending from the sidewalls to the beads. A concave curved surface extends on an outer surface of the clinch portion in a circumferential direction. A convex curved surface formed on a radially outer side end of a rim flange is engageable with the concave curved surface. A ratio R/R of curvature radius Rof the concave curved surface to a curvature radius R of the convex curved surface of the rim flange satisfies 1.7≤R/R≤2.5. The curvature radii Rand R of the concave and convex curved surfaces, respectively, are each a radius of curvature of an arc on a cross-section taken along a plane including a tire center axis.
