A normal rim 48 includes a flange 54. The flange 54 forms an outer circumferential bent surface 60 that is bent with a radius Rr of curvature. A first reference line L1 represents a straight line that extends through a center point Pr of the radius Rr, and that is tilted by an angle of 45°. In a state where the tire is inflated to a normal internal pressure and is under 120% of a normal load, Te represents a thickness from an inner cavity surface to an outer surface of the clinch, Tf1 represents a thickness of a filler, Tc1 represents a thickness of the clinch, Ta1 represents a thickness obtained by the thickness Tf1 and the thickness Tc1 being added, and the thicknesses are measured along the first reference line L1, and a ratio (Ta1/Te) of the thickness Ta1 to the thickness Te is greater than 0.4. |
