A polymer composition includes a conjugated diene polymer (A) and a compound (B). The compound (B) is at least one compound selected from the group consisting of a polysiloxane compound and a fluorine-containing compound. The conjugated diene polymer (A) contains, when the composition ratios (molar ratios) in the polymer of the structural units represented by formulas (1) to (4) are p, q, r, and s, respectively, a polymer (A-1) satisfying formula (i).0.75≤(p+(0.5×r))/(p+q+(0.5×r)+s)≤0.95 Formula (i):
