In a pneumatic tire 1, a belt layer 4 includes a plurality of belt members that are superposed. The belt members include a high-angle belt 41, a pair of cross belt 42 and a cross belt 43 that are arranged on a tire-radial direction outer side with respect to the high-angle belt 41, a first circumferential-direction reinforcing layer 44 that is arranged between the cross belt 42 and the cross belt 43 and that has two edges positioned on a tire-width direction inner side with respect to two edges of the cross belt 42 on a tire-radial direction inner side and two edges of the cross belt 43 on the tire-radial direction outer side, and a second circumferential-direction reinforcing layer 46 that is arranged between the carcass layer 3 and the cross belt 42 on the tire-radial direction inner side. The edge of the first circumferential-direction reinforcing layer 44 on the tire-width direction outer side and the edge of the second circumferential-direction reinforcing layer 46 on the tire-width direction outer side are at approximately the same position in a tire width direction. |
