Abstract
A rubber composition wherein a compounding amount of a solution-polymerized polystyrene butadiene rubber is 50 parts by mass or more and a compounding amount of a zinc-containing compound is less than 0.5 parts by mass, based on 100 parts by mass of a total amount of rubber components. It is preferable that the solution-polymerized polystyrene butadiene rubber is a solution-polymerized polystyrene butadiene rubber whose molecular terminal is modified.
