RUBBER COMPOSITION FOR TIRE, TREAD RUBBER, AND TIRE

A rubber composition for a tire, comprises a rubber component, a resin component, and a filler, wherein: the rubber component contains a rubber having isoprene skeleton and a styrene-butadiene rubber; the styrene-butadiene rubber has a glass transition temperature lower than -40 °C; a content of the resin component is in the range of ≥ 1 and < 50 parts by mass with respect to 100 parts by mass of the rubber component; the resin component has been at least partially hydrogenated and a difference in SP value between the resin component and the isoprene skeleton rubber is ≤ 1.40 (cal/cm); and the rubber composition satisfies the formula shown below: a mass ratio of the resin component/the isoprene skeleton rubber is ≥ 0.5.
