The present invention provides a pneumatic tire which achieves both a steering stability and a durability. The pneumatic tire has a toroidal carcass layer (4) between a pair of bead portions (1), a belt layer (5) on the outer side of the carcass layer (4) along the radial direction of the tire, and a first fiber reinforcing layer (6) which is arranged on the outer side of the belt layer (5) along the radial direction of the tire so as to cover both end portions (5a, 5b) of the belt layer (5), wherein a reinforcing rubber layer (7) is arranged between the first fiber reinforcing layer (6) and the belt layer (5) at a shoulder portion (S) at one side at which the shoulder portion is positioned at an inner side of the vehicle at the time of installing the tire, and a second fiber reinforcing layer (8) is arranged in adjacent to the outer side or the inner side of the first fiber reinforcing layer (6) at a shoulder portion (S2) at the other side at which the shoulder portion is positioned at the outer side of the vehicle, and wherein a peeling strength of the reinforcing rubber layer (7) is higher than a peeling strength of the belt layer (5) and the first fiber reinforcing layer (6).
