A polymer composition includes a conjugated diene-based polymer (A) and a liquid polymer (B), wherein: the conjugated diene-based polymer (A) includes a polymer (A1) satisfying expression (i) when a composition ratio (molar ratio) of a structural unit represented by formula (1), a structural unit represented by formula (2), a structural unit represented by formula (3) and a structural unit represented by formula (4) in the polymer is p, q, r and s, respectively; a glass transition temperature of the polymer (A1) is -40°C or less; and the liquid polymer (B) is polybutadiene, polyisoprene, polyisobutylene, polybutene, or the like. Expression (i):0.75 ≤ (p + (0.5 × r))/ (p + q + (0.5 × r) + s) ≤ 0.97.
