Abstract:
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 1 , R 2  and R 3  each 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 1 , R 2  and R 3  is an acyl group, R 4 , R 5  and R 6  each 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 (R 4 O) a , (R 5 O) b  and (R 6 O) c , consists of an oxyethylene group. A pneumatic tire manufactured using the rubber composition is disclosed.
