A tire tread composition includes a quantity of an elastomer and a quantity of a hydrocarbon resin substantially evenly distributed throughout the elastomer. The elastomer includes natural rubber. The hydrocarbon resin has a predetermined miscibility in the natural rubber. The predetermined miscibility is measured by a deviation of actual Tg for an elastomer-resin mixture consistent with the elastomer and hydrocarbon resin used in the tire tread composition from predicted Tg as calculated. In particular, the predetermined miscibility in the natural rubber is less than about six percent (6%) deviation in the actual Tg from the predicted Tg at a 20 phr loading.
