The present invention relates to a pneumatic tire. The pneumatic tire includes a carcass composed of one or more carcass plies that extend to span a tread, sidewalls, and bead parts. Ring bead sheet cords having a predetermined longitudinal length are disposed on both sides of the carcass plies. Each bead part-side end of the carcass plies is interposed between the ring bead sheet cords. The ring bead sheet cords are each formed in a closed ring shape having no disconnection along a circumferential direction of the tire. Spaces between the ring bead sheet cords are filled with a rubber mixture. Therefore, the tire of the present invention can provide an excellent advantage of durability and manufacturing process efficiency. |
