A tire/wheel structure includes a body, such as an automobile tire, and guide blocks mounted to two sidewalls of the body in a circumferentially arranged cascade series. Each guide block has a side facing a forward rotation direction of the body and forming at least one inclined guide face in such a way that the inclined guide face and an adjacent one of the guide blocks define therebetween a wind-assisting groove, whereby when the body is in a forward rotating condition, the inclined guide faces of the guide blocks and the wind-assisting grooves help enhance airflow guiding, reduce wind resistance, and generating an assistive driving force and when the inclined guide faces of the guide blocks and the wind-assisting grooves are moved to a position in a lower half of the circumference of the body, a follow-the-trend driving assisting force and a moving stabilizing effect are achieved. |
