the first belt (1) and the second belt (2) installed between a carcass layer (3) and a tread (4); cords (11); a coupling reinforce band (5); and left and right belts (1) (2). The radial tire is designed to reduce its weight to improve the combustion efficiency, facilitate diffusion of the heat and prevent separation of the tire at the coupling section, which is the most weak point in a tire.
