The tread rubber material of the all-steel radial tire with low rolling resistance provided by the invention is prepared by mixing the following components in parts by mass: 93 parts of 3 # smoke sheet rubber, 7 parts of neodymium butadiene rubber, 35 parts of medium super wear-resistant furnace black, 20 parts of high-dispersion white carbon black and 2.5 parts of silane coupling agent Si-69. The rubber is prepared from the following components in parts by weight: 3.2 parts of zinc oxide, 1.8 parts of stearic acid, 1.5 parts of an anti-aging agent RD, 0.5 part of an anti-aging agent 6PPD, 0.5 part of microcrystalline wax, 1.5 parts of sulfur, 1.8 parts of an accelerant TBBS and 0.2 part of a scorch retarder CTP. By adopting a low-hysteresis matched rubber material system, after the components are matched with one another, the produced rubber material is excellent in performance in all aspects, good in rebound resilience and abrasion resistance and particularly more remarkable in rolling resistance performance, the tan delta value of the produced rubber material at 60 DEG C is 0.04-0.06, and the rubber material has the advantages that the rubber material can be widely applied to the fields of rubber materials, rubber materials and the like. And the rolling resistance coefficient of the produced tire reaches grade B.
