PROBLEM TO BE SOLVED: To attain enhancement of high speed durability, linear advancement stability and turning stability, and to perform stable traveling by enhancing linear property of ground-contact feeling and rigidity feeling when it is transferred from the linear advancement traveling state to the turning traveling state or it is transferred from the turning traveling state to the linear advancement traveling state. SOLUTION: In the pneumatic tire for the two-wheel vehicle, a spiral belt layer 21 is provided between a carcass layer 9 and a tread part 13 and is formed by helically winding a ribbon-like strip material covering a belt cord 23 with a rubber in a circumferential direction C. Divided inclination belt layers 25 formed by covering a plurality of belt cords 27 inclined/extended relative to a tire circumferential direction C with a rubber are provided on a pair of shoulder side portions of the spiral belt layer 21 respectively. Further, an auxiliary spiral belt layer 29 is provided on a center side portion of the spiral belt layer 21 and is formed by helically winding a ribbon-like strip material covering a belt cord 31 with a rubber in a tire circumferential direction.
