A rubber composition includes: a rubber component; a filler in an amount of 40 to 125 parts by mass per 100 parts by mass of the rubber component; and a hydrogenated resin in an amount of 5 to 50 parts by mass per 100 parts by mass of the rubber component, the resin having a softening point of higher than 110°C and a weight average molecular weight, as determined in terms of polystyrene, of 200 to 1200 g/mol. The rubber composition can be used to produce a tire having an excellent wet grip performance and a low rolling resistance, and a vulcanized rubber having excellent handling properties.
