The present invention relates to a pneumatic tire (1) having a dual reinforcing belt structure, which minimizes deformation of the tire tread section (11) during high-speed driving, particularly deformation of the tire shoulder parts, suppresses a standing wave phenomenon, and enhances driving stability. The pneumatic tire having a dual reinforcing belt structure according to the invention includes a tread section (11), a sidewall section (12) and a bead section (14), in which the bead section is provided with a carcass (15) in a turned-up manner, a plurality of belt layers are provided by lamination between the carcass (15) and the tread section (11), and a reinforcing belt (100) is provided on top of the belt layer (16), while the reinforcing belt (100) is a dual reinforcing belt in which belts made of different materials are arranged. According to the configuration of the invention, there is obtained an effect that the growth of the tire tread shoulder parts and a standing wave are suppressed during high-speed driving, the tire cornering performance is enhanced to thereby enhance driving stability, repeated deformation and momentum in the belt section caused by dimensional growth of the tire are increased, and a potential problem that separation between the belt layers is accelerated is prevented.
