The invention discloses snowfield tricycle tread rubber and a preparation process thereof, and relates to the technical field of tread rubber. Comprising the following raw materials in parts by weight: 50 to 55 parts of natural rubber, 25 to 30 parts of solution polymerized styrene-butadiene, 23 to 28 parts of butadiene rubber, 57 to 63 parts of carbon black, 12 to 18 parts of high-dispersion white carbon black, 3 to 5 parts of a silane coupling agent SI69, 17 to 23 parts of aromatic oil, 4 to 6 parts of zinc oxide, 0.75 to 1.25 parts of stearic acid SA, 1.5 to 2.5 parts of an anti-aging agent 4020, 0.75 to 1.25 parts of an anti-aging agent RD, 0.75 to 1.25 parts of an anti-aging agent DTPD3100, 1.5 to 2.5 parts of protective wax, 1.5 to 2.5 parts of a white carbon black dispersing agent and 0.5 to 0.8 part of an accelerant. 1.5 to 2 parts of sulfur; and 0.1 to 0.3 part of scorch retarder CTP. According to the snowfield tricycle tread rubber and the preparation process thereof, the prepared tread rubber has a relatively good anti-skid effect under the action of the combination of the solution polymerized styrene-butadiene rubber SSBR2438 and the high-dispersity white carbon black 7000 GR and the silane coupling agent, and in the preparation process, the vulcanization efficiency is improved due to the addition of the sulfur and the accelerant.
