The invention relates to an air pressure tire capable of improving the heat radiation performance by preventing the tire from being cracked or separated by continuous heating on the shoulder portion of a tire so that heat can be easily radiated from the inside to the outside. The air pressure tire comprises a belt portion (1) heaped with multilayers on a crown portion of the carcass (4); a heat radiating wire (5) of copper or aluminum, excellent in transmissibility, installed in the inside of both shoulder portions (2) which are belt edge portions (11) multiplayered; a heat radiating wire installed in the inside of shoulder portion (2) in a slope to be correspondent to the gradient of shoulder portion (2), and means for keeping the gradient angle at a range of 30~60 degree; the heat radiating wire (5) arranged in a zigzag with many wires and in the form of undress; the wire surface able to be processed both concavly and convexly and able to be worked with electric coating and chemical processing. The durability of a tire can be improved.
