摘要:
Provided is a rubber composition for a tire tread containing: a diene rubber; silica in an amount of from 60 to 200 parts by mass per 100 parts by mass of the rubber; a polysiloxane represented by the average composition formula: (A)a(B)b(C)c(D)d(R1)eSiO(4-2a-b-c-d-e)/2; and an alkyl triethoxysilane having an alkyl group with from 7 to 20 carbon atoms. Also provided is a pneumatic tire using this rubber composition in the tire tread.
