The invention relates to the technical field of tire rubber, in particular to a four-season all-steel ice and snow tire tread rubber composition. The composition comprises the following steps, by weight, after mixing: 10-30 parts of natural rubber, 10-35 parts of liquid rubber, 65-80 parts of functionalized solution polymerized styrene-butadiene rubber, 5-25 parts of carbon black, 20-55 parts of white carbon black with a low specific surface area, 4.0 -12.0 parts of a silane coupling agent ranges, 1.5-3.0 parts of white carbon black dispersing agent, 2.0-5.0 parts of zinc oxide, 1.0-3.0 partsof stearic acid, 1.0-3.0 parts of an anti-aging agent 4020, 1.5-2.5 parts of an anti-aging agent RD, 1.0-4.0 parts of rubber protective wax, 1.5-2.5 parts of sulfur S-80, 1.0-3.5 parts of tear-resistant resin, 1.0-2.5 parts of an accelerant NS-80 and 0-0.5 part of an accelerant DPG-80. The tire tread produced by the invention not only has excellent snowfield grip on a snowfield pavement, but alsokeeps excellent grip on an all-ice pavement, and has excellent rolling resistance, wet skid resistance and wear resistance.
