Abstract
A pneumatic tire has two belt layers, each having a plurality of strip pieces formed by pulling together and rubberizing a plurality of steel cords. Strip piece width, strip piece thickness, belt layer cord angle with respect to a tire circumferential direction, numbers of the strip pieces of inner and outer belt layers, and circumferential lengths of the inner and outer belt layers are respectively denoted by A, G, θ, N, N, Land L. Nis equal to N, and Nis an integer satisfying L=N×A/sin θ. The inner belt layer is formed by joining the Nstrip pieces so each side of each strip piece is butted with one side of another strip piece. The outer belt layer is formed by aligning the Nstrip pieces on the inner belt layer in the tire circumferential direction with spaces of width 2πG/Ndisposed between adjacent strip pieces.
