The present invention provides a rubber composition for tires capable of improving wet grip performance and low rolling resistance above conventional levels while maintaining and improving mechanical properties such as tensile stress, tensile strength at break, and tensile elongation at break. . It is characterized in that the particle complex composed of the solid content of a mixture of an emulsion of organic particles and a rubber latex is compounded with a rubber capable of sulfur vulcanization, and the emulsion of the organic particles is an emulsion containing the particles prepared as follows: At least one substance selected from the group consisting of polymerizable monomers and oligomers, prepolymers and polymers with a molecular weight of 500 to 50,000 having reactive functional groups is simultaneously or gradually polymerized and/or cross-linked in water to obtain The resulting fine particles have an average particle diameter of 0.001 to 100 μm. |
