A pneumatic tire is provided to prevent a sudden outbreak of heat separation on the driving of a vehicle by efficiently discharging the heat accumulated at the shoulder. A pneumatic tire comprises heat radiation portion provided on the transversal groove(10a) of the shoulder to externally radiate the heat generated from the tire. The heat radiation portion includes a heat absorption plate(120) provided on the upper part of a capply(7) edge(E) to absorb the heat generated from the capply and a belt(6), a heat radiation plate(160) exposed on the bottom of the transversal groove to externally radiate the heat absorbed from the heat absorption plate, and a heat transfer plate(140) interposed between the heat absorption plate and the heat radiation plate to transfer the heat in the heat absorption plate to the heat radiation plate.
