Abstract
A diene-based rubber contains natural rubber and specific conjugated diene-based rubber. The content of the natural rubber in the diene-based rubber is 30 to 45 mass %. The content of the specific conjugated diene-based rubber in the diene-based rubber is 30 to 70 mass %. The specific conjugated diene-based rubber is conjugated diene-based rubber produced according to a specific production method. In the conjugated diene-based rubber, the aromatic vinyl unit content, the vinyl bond content, and the weight average molecular weight are within a predetermined range. The CTAB adsorption specific surface area of the silica is 180 m/g or greater. The content of the silica is less than 60 parts by mass per 100 parts by mass of the diene-based rubber.
