Abstract

PURPOSE: To improve durability under a low internal pressure by a method wherein rubber layers having specified hardness are interposed between a belt layer and a carcass ply layer and between the belt layer and a tread rubber in a radial tire having steel chord belt layers.
CONSTITUTION: A shoulder portion 3 for a radial tire is provided between a carcass chord ply layer 1 and a tread rubber layer 8 and a reinforcing rubber layer 4, having a shore hardness of 65°W85° after vulcanized and a crescent moon type section, is provided in the shoulder portion 3 having two sheets of steel chord belt layers 6 arranged so as to intersect with an equatorial line of the tire by an angle of 10°W30°. This rubber layer 4 is provided by adhering beforehand on an outer side of the layer 1 within a range of 5W20mm toward inner side of an axial direction of the tire and 10W30mm toward outer side of the same with respect to a center which is an end portion 7 of the belt layer 6. Further, the tread rubber 8 integrally molded with a reinforcing rubber layer 9 of the same material as that of the reinforcing rubber layer 4 and having a crescent moon type section is bonded on an outside of the belt layer 6.
