The invention provides a crawler wheel side rubber composition, crawler wheel side rubber and application thereof, and particularly relates to the technical field of tire manufacturing. The crawler wheel side rubber composition is prepared from the following components in parts by weight: 15 to 55 parts of natural rubber, 45 to 85 parts of chloroprene rubber, 12 to 32 parts of carbon black, 7 to 16 parts of white carbon black, 30 to 65 parts of a flame retardant, 5 to 10 parts of an activating agent, 0.5 to 1.5 parts of an activating auxiliary agent, 1 to 3 parts of an anti-aging agent, 1 to 4 parts of a vulcanizing agent and 2.5 to 4.5 parts of an accelerant, the flame retardant comprises antimony trioxide. According to the crawler wheel side rubber composition provided by the invention, through the synergistic effect of the raw materials, the maintenance of physical properties is ensured while the flame retardant property is improved, and dual optimization of the flame retardant property and the physical properties is realized. Meanwhile, the invention provides a mixing method of the crawler wheel side rubber, and the problem that high-part white carbon black is not easy to disperse is solved.
