摘要： A light weight pneumatic tire having a thin side wall rubber is disclosed. The thin side wall rubber has previously been squeezed on that region of the outer surface of an upper ply which corresponds to the side wall portion of the tire prior to the tire shaping step, and has a Shore A hardness after vulcanization of 40.degree. to 55.degree., an excellent flex-cracking and weather resistant property. The upper ply is superimposed about at least a portion extending from a hump portion to a bead portion is composed of cords coated with a high resilient rubber. A tread rubber layer is extended across the thin side wall rubber layers and pressed and made integral therewith by stitching.
