Abstract:
A rubber composition for sidewall contains 10 to 40 mass % syndiotactic-1,2-polybutadiene-containing polybutadiene rubber and 10 to 30 mass % tin-modified polybytadiene rubber in a polymer component, and contains 10 to 40 parts by mass silica with respect to 100 parts by mass polymer component. Thus, cut resistance and ozone resistance as well as fuel efficiency of a car can be improved.
