A light-weight heavy-duty radial tire is formed with at least one carcass ply and at least two tread plies. The tensile strength T, expressed in kilograms, of the plies per centimeter of ply width is reduced to a value between 5 and 15 times the inner radius R, expressed in centimeters, of the tire in the median plane. The tire is of substantially reduced weight and is inflated to a pressure which is 20% to 30% less than the nominal inflation pressure for conventional tires of the same size bearing the same load. |
