RUBBER COMPOSITION FOR TIRE AND PNEUMATIC TIRE

Processability and abrasion resistance are improved in a rubber composition having silica added thereto. The rubber composition for a tire comprises a diene rubber, silica and an ether ester that is monoester and/or diester of polyoxyalkylene glycerin fatty acid ester represented by the following formula (1): wherein R, Rand Reach represent a hydrogen atom or an acyl group having a saturated or unsaturated alkyl group having 6 to 30 carbon atoms, provided that at least one of R, Rand Ris an acyl group, R, Rand Reach independently represent an alkylene group having 2 to 4 carbon atoms, a, b and c each independently represent an average number of moles added and 60 mass % or more of (RO), (RO)and (RO), consists of an oxyethylene group. A pneumatic tire manufactured using the rubber composition is disclosed.
