To provide an in-wheel motor system which can sufficiently secure space in a wheel for arranging an in-wheel motor in a wheel and has improved shock resistance and vibration ride quality with respect to the motor.
The in-wheel motor 13 is disposed in the wheel 12. An improved flat tire 11 having a carcass ply 11A comprising a widened section 11a which increases in width from the maximum diameter section of the tire toward the center of the tire and has the maximum width at its end and a throttle section 11b which joins to the maximum width section of the widened section 11a and narrows from the maximum width section, and having a belt layer 11C arranged in the direction intersecting the carcass ply 11A is mounted to the wheel 12. The ratio of the diameter of the minimum diameter section of a wheel rim section to the tire outer diameter is set to 70% or more, and the longitudinal spring constant indicating rigidity in the tire radial direction is set as 200-350 N/mm, lower than that of the conventional low flat tire.
