The invention provides a high-performance truck tire tread rubber material. The high-performance truck tire tread rubber material is prepared from the following raw material components: 25-35 parts of natural rubber; 30-40 parts of butadiene rubber; 15-25 parts of styrene butadiene rubber; 1-3 parts of sulfur; 1-4 parts of an accelerant; 5-10 parts of modified resin; 40-60 parts of high wear resistance carbon black; 10 to 20 parts of white carbon black; 3-5 parts of zinc oxide; 3-5 parts of stearic acid; 1-4 parts of a silane coupling agent; and 1-3 parts of an anti-aging agent. Compared with a conventional truck tire formula and unmodified resin, the rubber material prepared from the modified resin has the beneficial effects that the wear resistance is enhanced, the rolling resistance is reduced, and the wet skid resistance is also improved.
