Provided is a rubber composition for tire tread containing: a diene rubber; silica in the amount of 60-200 parts by weight with respect to 100 parts by mass of the rubber; a polysiloxane represented by Formula: (A)a(B)b(C)c(D)d(R1)eSiO(4-2a-b-c-d-e)/2 (the formula is an averaged compositional formula in which A represents a bivalent organic group containing a sulfide group, B represents a C5-10 monovalent hydrocarbon group, C represents a hydrolyzable group, D represents an organic group including a mercapto group, R1 represents a C1-4 monovalent hydrocarbon group, and a-e satisfy the relational formulae 0<=a<1, 0<=b<1, 0<=e<2, and 0<2a+b+c+d+e<4, with the caveat that either a or b is not 0.); and an alkyl triethoxysilane containing a C7-20 alkyl group. Also provided is a pneumatic tire using this rubber composition in the tire tread.
