PURPOSE: A pneumatic tire having the improved heat-radiating performance is provided to improve the durability and to delay the performance decline of a tire by radiating the heat generated by bending and stretching of a tire to the air. CONSTITUTION: A pneumatic tire is composed of a tread, a heat pipe, a belt layer, a shoulder, a side wall, a bead, a metal heat radiating plate, and a wheel. The heat pipe is installed to be contacted to the wheel from the lower part of the tread. The heat generated from the tread, the belt layer, and the shoulder passes the side wall after passing the inside of the tread and the shoulder. The heat passing the side wall is radiated to the air by the wheel.
