A rubber composition, contains a rubber component, a filler, and a resin, wherein: the rubber component contains natural rubber, a high-Tg modified styrene-butadiene rubber, and a low-Tg modified styrene-butadiene rubber having a lower glass transition temperature (Tg) than the high-Tg modified styrene-butadiene rubber; both ends of the high-Tg modified styrene-butadiene rubber have been modified and at least one end thereof has been modified with an alkoxysilane; one end of the low-Tg modified styrene-butadiene rubber has been modified with an alkoxysilane; and a mass ratio of the high-Tg modified styrene-butadiene rubber (high-Tg modified SBR) content with respect to the low-Tg modified styrene-butadiene rubber (low-Tg modified SBR) content, i.e., high-Tg modified SBR content/low-Tg modified SBR content, is larger than 1.
