(57) [Abstract] [Problem] Having sufficient grip force and low heat generation performance, To provide a rubber composition excellent in processability and durability. SOLUTION: The rubber composition of the present invention comprises a diene rubber, It comprises a reinforcing agent and a compound represented by the following general formula (I). R in the general formula (I) Is a hydrogen atom, X is an oxygen atom, n is an integer of 1 to 3, and A is a hydrogen atom or an n-valent arylcarbonyl or alkenylcarbonyl group. The diene rubber is one or more selected from the group consisting of natural rubber, polyisoprene rubber, styrene butadiene rubber, polybutadiene rubber, butyl rubber, and ethylene-propylene-diene rubber. The pneumatic rubber tire obtained using the rubber composition of the present invention is particularly useful. Embedded image |
