An object of the present invention is to provide a pneumatic tire in which the structure of a reinforcing layer is optimized to prevent a carcass from being separated from rubber and reliably prevent the carcass from being pulled out of a bead portion, thereby improving durability of the bead portion. The pneumatic tire has a carcass 5 formed of at least one ply constituted of: a main body 3 extending in a toroidal shape over respective portions including a pair of bead portions 1 having bead cores 2 embedded therein, a pair of sidewall portions extending on the outer side in the tire radial direction from the bead portions 1, and a tread portion extending over the respective sidewall portions; and a folded portion 4 extending from the main body 3 and being folded around the respective bead cores 2 from the inner side toward the outer side in the tire widthwise direction. The tire further comprises at least two reinforcing layers 8 formed of cords 7 extending substantially in the tire circumferential direction and rubber coating thereon, the reinforcing layers 8 being disposed along the inner face of the carcass 5 on the inner side in the tire widthwise direction of the bead core 2.
