Pneumatic tire using carcass ply

摘要

A pneumatic tire has two or more carcass layers for reinforcing between a pair of annular beads. The pneumatic tire includes: (i) 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; (ii) 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 (iii) a region between the radial region and a tire equator line, which region includes another bias region.
