Abstract
A pneumatic tire includes a carcass ply with carcass cords. The carcass cords comprise high tenacity vinylon fiber, polyethylene naphthalate fiber or polyalylate fiber. Viscoelasticity characteristics per one cord at 120° C. of the carcass cord satisfy the following equations (1) to (3):B>0  (1)≦0.0000437×+0.042857  (2)≦−0.00003636×+0.163636  (3)(wherein 'A' represents a product of complex modulus E*(N/cm) and cross-sectional area 'S' (cm) of cord), and “B” represents a loss tangent tanδ).
