The invention discloses a tread rubber composition of an all-steel truck snow tire. The tread rubber composition is characterized by being composed of, by weight, 42-62 parts of natural rubber, 15-35 parts of oil-extended neodymium-based butadiene rubber, 25-34 parts of solution-polymerized styrene-butadiene rubber, 23-38 parts of high-dispersion white carbon black, 30-55 parts of carbon black N220, 2-4 parts of coupling agent liquid Si69, 1-10 parts of aromatic oil, 2-8 parts of zinc oxide, 0.5-3 parts of stearic acid, 2-4 parts of antiager 6PPD, 1.5-3 parts of antiager RD, 2-5 parts of microcrystalline wax, 1-3.5 parts of oil-extended sulfur, 1-2.5 parts of accelerator NS, 0.1-1 part of accelerator DPG and 0.1-0.5 part of scorch retarder CTP. By the adoption of the solution-polymerized styrene-butadiene rubber with the Tg appropriate to that of natural rubber, the neodymium-based rare-earth butadiene rubber with the lower Tg and white carbon black commonly used for semi-steel snow tires, at a specific proportion, the tire is moderate in tread hardness and good in elasticity, and has the advantages of excellent snow slip resistance, good snowfield road holding, high snowfield indexes and the like in a freezing snowfield.
