An object of the present invention is to provide a rubber composition that is excellent in modulus and workability while maintaining high elongation at break and excellent low heat generation, and capable of reducing permanent strain. At least one selected from the group consisting of black and white filler, acid-modified polyolefin, and polyamide polyether elastomer, and at least one content selected from the group consisting of carbon black and white filler Is 1 to 100 parts by mass with respect to 100 parts by mass of the diene rubber, and the total content of the acid-modified polyolefin and the polyamide polyether elastomer is 3 with respect to 100 parts by mass of the diene rubber. It is a rubber composition which is -35 mass parts, and a pneumatic tire using this. |
