The invention discloses a preparation method of a polyester composition and application of the polyester composition in rubber, and relates to the technical field of TBR tread rubber compositions. The rubber composition is prepared from the following components in parts by weight: 100 parts of diene rubber, 0-70 parts of carbon black, 0-70 parts of white carbon black, 0-7 parts of a silane coupling agent, 0.2-15 parts of a polyester composition, 0.5-4 parts of a vulcanizing agent and a conventional auxiliary agent. The rubber composition provided by the invention has the beneficial effects that in a formula using white carbon black, the tensile strength, tensile strength and hardness consistent or better than those of a pure carbon black formula are achieved, good bearing capacity and consistent wear resistance of a tire are ensured, and the rubber composition has more excellent tear resistance and cutting resistance, and is suitable for large-scale popularization and application. The rolling resistance is obviously reduced, and the anti-reversion performance is excellent.
