PROBLEM TO BE SOLVED: To provide an in-wheel motor system capable of protecting an in-wheel motor by reducing impact and vibration to the motor also at the time of puncture without lowering riding comfort. SOLUTION: This system is provided with the in-wheel motor 13 for directly driving a wheel 12 at the inside of the wheel 12. At the inside of a tire 11 sectioned by a rim 12a of the wheel 12 and the tire 11 mounted on the rim 12a, many substantially spherical particles 11P made of resin continuous phases and closed cells and having an average bulk density of≤0.1 under atmospheric pressure are arranged so that pressure at 25°C at the inside of the tire 11 may be≥150 kPa and≤900 kPa in absolute pressure.
