Abstract: A proper balance between ride comfort, steering stability, and road noise is achieved. A pneumatic tire (1) has a band layer (9) comprising a band ply (9A) where band cords are arranged at an angle of not more than 5 deg. with respect to the circumferential direction of the tire on the radially outer side of a belt layer (7). The band ply (9A) comprises a first ply piece (9a) covering only one side of end portions of the belt layer (7) and a second ply piece (9b) disposed adjacently to the first ply piece (9a), covering continuously the central portion of the belt layer (7) and another side of the end portions, and having a width larger than that of the above-mentioned first ply piece (9a). And, the band cords of said first ply piece (9a) and band cords of said second ply piece (9b) are different in modulus.
