Provided are an elastomer composition and a tire capable of changing tire performance in response to changes in temperature. The present invention relates to an elastomer composition, containing a butadiene-based elastomer, and a temperature-responsive resin that changes its hydrophilicity with changes in temperature, the elastomer composition satisfying the following relationships at two given temperatures differing by at least 10°C: (Elastic modulus at lower temperature and when immersed in water)/(Elastic modulus at lower temperature and when dry) ≤ 0.95, and (Elastic modulus at higher temperature and when immersed in water)/(Elastic modulus at higher temperature and when dry) > 0.95, the lower temperature being lower than 25°C.
