Pneumatic tire using carcass ply

A pneumatic tire comprising two or more carcass layers for reinforcing between a pair of annular beads, said pneumatic tire including:

• a region including or near a position having a tire maximum width, which region includes a radial region where cords constituting the carcass layers are arranged at an angle of 90±10° with respect to a circumferential direction;
• a region between the radial region and one of the beads close thereto, which region includes a bias region where cords in an upper layer and cords in a lower layer constituting the carcass intersect and are both arranged at an angle of 10° to 60° with respect to the circumferential direction;
• and
• a region between the radial region and a tire equator line, which region includes another bias region where cords in an upper layer and cords in a lower layer constituting the carcass intersect and are both arranged at an angle of 10° to 60° with respect to the circumferential direction.
