ABSTRACT:
A pneumatic tire has organic fiber carcass cords. The organic fiber carcass cords comprise double-twisted fiber yarns and satisfy the following equations. ##EQU1## where D.sub.1 is the original denier, D.sub.2 is the total of the original denier, N.sub.1 is a ply-twisting coefficient, N.sub.2 is a cable-twisting coefficient, n.sub.1, is the ply-twisting number (turns/10 cm), n.sub.2 is the cable-twisting number (turns/10 cm) and .rho. is the specific gravity of the organic fiber.
