Abstract:
The present invention aims to provide rubber compositions for tires that contain a natural rubber achieving a balanced improvement in abrasion resistance, breaking performance, and processability to achieve a balanced improvement in abrasion resistance, breaking performance, and processability, and also provide pneumatic tires containing such rubber compositions for tires. Included is a rubber composition for tires comprising a modified natural rubber prepared by treating natural rubber latex with a proteolytic enzyme, and then treating the treated natural rubber latex with a lipolytic enzyme and/or a phospholipid degrading enzyme. Also included is a rubber composition for tires, comprising a modified natural rubber prepared by centrifuging natural rubber latex to recover a latex fraction comprising latex particles having an average particle size of 0.25 μm or less.

Claim (Index 7):
The rubber composition for tires according to  claim 1 ,\n wherein the modified natural rubber is prepared by further coagulating the resulting latex fraction with (1) an acid and (2) at least one of: (i) at least one salt selected from the group consisting of calcium salts, sodium salts, potassium salts, and ammonium salts of nitric acid, sulfuric acid, carbonic acid, phosphoric acid, hydrochloric acid, and formic acid; and (ii) a polymer flocculant.
