1. A rubber composition for a tire tread, comprising
a diene-based rubber component;
a microcrystalline wax having a melting point of from 72 to 84° C.; and
an aluminum hydroxide having a nitrogen absorption specific surface area of 3.0 to 60.0 m2/g,
wherein the microcrystalline wax comprises a branched alkane of 40 to 70 carbon atoms and a linear alkane of 45 or more carbon atoms, and,
wherein, based on 100 parts by mass of the diene-based rubber component, a content of the branched alkane of 40 to 70 carbon atoms is 0.5 to 6.0 parts by mass, a content of the linear alkane of 45 or more carbon atoms is 0.05 to 3.5 parts by mass and a content of the aluminum hydroxide of a nitrogen absorption specific surface area of 3.0 to 60.0 m2/g is 1 to 35 parts by mass.
