A polymer composition includes a conjugated diene-based polymer (A) and a liquid polymer (B). 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.0.75(p+(0.5×r))/(p+q+(0.5×r)+s)≤0.97  Expression (i)
