A tire/wheel assembly, wherein bent parts ( 4 f) bent outward are formed at the leg end parts of an annular shell ( 4 ), an inclination angle (alpha 1 ) of a line segment L 1 extending from the axially outer end (P 3 ) of the bent part ( 4 f) through the apex (P 1 ) of a hump ( 1 f) on a rim relative to a direction perpendicular to a tire axis is set to within ±5° in a cross section orthogonal to the circumferential direction of the annular shell ( 4 ), the area ( 4 s) of the annular shell equal to the height (B) of at least 35% of the height (A) from the radially inner end of the annular shell is formed linearly, the inclination angle (alpha 2 ) of an extension line (L 2 ) along the inner surface of the linear area ( 4 s) relative to the direction perpendicular to the tire axis is 15 to 30° in axial inner side, and the extension line (L 2 ) passes between the apex (P 1 ) of the hump ( 1 h) and the toe tip (P 2 ) of a tire bead part.
