Abstract
A pneumatic tire includes a tread, a carcass and a belt. The belt includes inner and outer layers including steel cords and topping rubbers such that the cords in each layer are parallel-aligned and inclined with respect to equatorial plane and inclination directions of the cords in the layers are opposite to each other with respect to the plane, inclination angle αs of the cords in the inner layer at edge is larger than inclination angle αc at the plane, the edge of the inner layer is at position of 0.9 times axial direction width, inclination angle βs of the cords in the outer layer at edge is larger than inclination angle βc o at the plane, the edge of the outer layer is at position of 0.9 times axial direction width, and difference between the angles αs and αc is larger than difference between the angles βs and βc.
