The technical problem of this disclosure is to provide a tire rubber composition capable of achieving a high degree of compatibility between the wet gripping performance and the fuel efficiency of a tire. The solution is a tire rubber composition containing: a rubber component containing an isoprene skeleton rubber and a modified styrene-butadiene rubber with a bound styrene content of 15% by mass or less; a hydrogenated resin having a softening point of higher than 100° C. and a weight-average molecular weight in terms of polystyrene (g/mol) of greater than 1200 and 1600 or less; silica; and carbon black, wherein a percentage of silica in the total amount of said silica and said carbon black is 50% by mass or more and less than 100% by mass.
