Abstract
A pneumatic radial tire has a carcass structure, a belt structure, and a tread. The belt structure has at least two plies of reinforcing cords, the cords in the at least two plies being inclined at angles greater than 5° relative to the tire centerline. The cords in the belt plies are inclined at equal but opposite directions relative to the tire centerline. The belt plies have a stiffness variation in the circumferential and meridional directions of the belt plies wherein the stiffness variation is in the range of 12 to 25% between a radially outermost belt ply and a radially innermost belt ply.
