A tire/wheel structure according to the present invention includes guide blocks that are mounted on two cylindrical side walls which are serially arranged like car tires. Each of the guide blocks includes a side that is formed in a forward rotation direction of the body and has inclined guide faces so that at least one inclined guide face and the adjacent guide block form an air auxiliary groove therebetween. In a case where the body is in a state of forward rotation, the inclined guide face of the guide block and the air auxiliary groove help improvement of air flow guide, reduction of air resistance, and generation of an auxiliary driving force. In a case where the inclined guide face of the guide block and the air auxiliary groove are moved to a lower-half position of the circumference of the body, the auxiliary driving force and a movement stabilization effect are acquired by following a trend. |
