    摘要: The present disclosure provides a rubber composition for a tire, comprising: an elastomer component containing a styrenic elastomer; and a short fiber resin wherein, in a cross section taken perpendicular to a longitudinal direction of the short fiber resin, provided that A is the length of the cross section along a longest diameter thereof and B is the length of the cross section along a short diameter thereof that is perpendicular to the longest diameter, A/B is larger than 2, wherein a content of butadiene rubber is in the range of 0 to 60 mass % and a content of the styrenic elastomer is in the range of 10 to 60 mass % in the elastomer component, and a content of styrene is in the range of 0.8 to 11 mass % with respect to the sum of the butadiene rubber and the styrenic elastomer.
