摘要:
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, N1, N2, L1 and L2. N2 is equal to N1, and N1 is an integer satisfying L1=N1×A/sin θ. The inner belt layer is formed by joining the N1 strip 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 N2 strip pieces on the inner belt layer in the tire circumferential direction with spaces of width 2πG/N2 disposed between adjacent strip pieces.
