<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire that reduces the weight thereof and improves durability performance.SOLUTION: The pneumatic tire comprises: at least one carcass layer 6, in which a plurality of cords are placed side by side in the tire circumferential direction, both ends in the tire width direction of which reach both bead portions 5 and are wound around and provided in the tire circumferential direction and which has divided portions 6A divided in the tire width direction at a tread portion 2; at least one belt layer 7 that is arranged outside in the tire radial direction of the carcass layer at the trad portion; and an inner liner 8 arranged on an inner circumferential surface of the tire inside the tire of the carcass layer. The inner liner has: a first inner liner 8A that is provided overlapping with at least part of the divided portions of the carcass layer, of the tread portion; and second inner liners 8B provided on both sides in the tire width direction of the first inner liner, where the first inner liner and the second inner liner have the same air permeation coefficient and average air permeation Vx of the first inner liner and average air permeation Vy of the second inner liner have a relation of Vx<Vy.</p> |
