Abstract: A tire includes a tread portion, a sidewall portion, and a bead portion. The bead portion includes a bead core that extends continuously in an annular shape in a tire circumferential direction, and a bead filler disposed adjacent to the bead core and outside the bead core in a tire radial direction. Reinforcing cords are provided in the bead portion and the sidewall portion so as to be curved such that inclination angles of the reinforcing cords with respect to the tire circumferential direction gradually increase with nearness to an outside in the tire radial direction.

Abstract: A pneumatic tire has a belt ply buried in a tread portion and a carcass ply running into an inner peripheral side of an end portion of the belt ply from a pair of bead portions. The carcass ply was divided in a tire width direction at the tread portion. A division width of the carcass ply is equal to or more than 35% of a maximum width of the belt ply. An auxiliary ply formed by reinforcement cords extending at an angle within a range of ±20 degrees with respect to the tire width direction is arranged in such a manner as to overlap with the carcass ply in an inner peripheral side of the end portion of the belt ply and extend out to an inner side in the tire width direction than the division end portion of the carcass ply.
