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.

Claim (Index 2):
The rubber composition for a tire according to  claim 1 , wherein the silica is contained in an amount of 20 to 120 parts by mass per 100 parts by mass of the diene rubber and the ether ester is contained in an amount of 1 to 10 parts by mass per 100 parts by mass of the diene rubber.
