Two carcass layers for reinforcing between a pair of annular beads are laminated such that cords are inclined substantially symmetrically with respect to the tire circumferential direction, an angle of the cords with respect to the tire circumferential direction in a region of 10% of a belt width from a widthwise end of the belt layer toward a tire equator is 40 to 80°, and an angle of the cords with respect to the tire circumferential direction in the vicinity of the tire equator and in the vicinity of the maximum width position is greater than the angle in the region by 5° and is 75° or greater.
