Provided is a method for producing a conjugated diene rubber tire that, in order to provide a conjugated diene rubber favorably used to provide a tire that is superior in strength, wet-grip properties, and low heat-generation properties, forms a polymer block (A) having active terminals containing a specific quantity of aromatic vinyl monomer units and isoprene monomer units using a polymerization initiator in an inert solvent, and then forms a polymer block (B) having active terminals containing a specific quantity of 1,3-butadiene monomer units and, as necessary, aromatic vinyl monomer units, thereby obtaining a conjugated diene polymer chain having active terminals and having the polymer block (A) and the polymer block (B), and then causes the reaction of a specific quantity of a predetermined denaturing agent with the active terminals of the conjugated diene polymer chain having active terminals. |
