The present invention is directed towards a pneumatic radial tire (10). The tire (10) is comprised of a reinforcing belt structure (32) wherein the belt plies (34, 36) are divided into at least three segments (34a,34b,36a,36b). The reinforcing cords in each segment of a ply (34, 36) are oriented in the same inclination direction. By maintaining the same cord inclination in the segments, dividing the belt ply into segments creates hinge points (38, 40) for the belt ply, reducing the stiffness of the ply across the width of the tread from the centerline CL of the tire to the tread edges (14, 16). If the belt structure (32) has more than one reinforcing ply, the segments (34a,34b,36a,36b) of the adjacent plies are staggered by a distance s greater than the radial height h between the radially inner sides of the adjacent belt plies (34, 36). <IMAGE> |
