Abstract: There is proposed a tire realizing the simplification of a bead portion structure without sacrificing a bead portion durability and a steering stability.A tire comprises a carcass toroidally extending between a pair of bead cores embedded in respective bead portions, in which the carcass is combined with the bead core through such a pathway that the carcass passes inside a thickness center of the bead portion in an axial direction of the tire and reaches to a face of the bead core inside the tire and then passes through the bead core from an inside of the tire toward an outside thereof and terminates in contact with a face of the bead core at a side of a bead base.
