Abstract:
In order to improve the uniformity of a tire, this pneumatic tire has: strips (a carcass layer (6), and an inner liner layer (8)) that wrap around in the tire circumferential direction, both edges of the strips, in the tire width direction, reaching bead sections on both sides; and a belt layer disposed outside of the strips in the tire radial direction in a tread section. The pneumatic tire is characterized in that the strips are divided in the tire width direction, and the divided strips (divided carcass layer (6A, 6B), and divided inner liner layer (8A, 8B)) have joints (6Ab, 6Bb, 8Ab, 8Bb) joined in the tire circumferential direction, and the mutual positions of the joints are disposed in a staggered manner at least 20° in the tire circumferential direction within a range (SW) between a tire maximum width position and the edges at a maximum width (TW), in the tire width direction, of the belt layer.
