The invention relates to the field of tires, and discloses a preparation method of a low-noise patterned tire, which comprises the following steps of: a, predicting the crosslinking density of tire rubber of each part of the tire by adopting simulation research, and adjusting the rubber formula of each part of the tire; b, the mold and the capsule are preheated to the preset preheating temperature through the shaping vulcanizing machine; c, during mold closing and vulcanizing of the shaping vulcanizing machine, the vulcanizing pressure is selected, and the crosslinking density of the tire rubber material is adjusted by adjusting the vulcanizing time and the vulcanizing temperature, so that the tire reaches the positive vulcanization state; e, after vulcanization is finished, vulcanization cooling is carried out; setting the crosslinking density G of the tire rubber material according to the rubber material heat transfer rate P; the cross-linking density G of the tire rubber material is corrected according to the vulcanization time T; and carrying out secondary correction on the corrected cross-linking density G of the tire rubber material according to the vulcanization temperature W. By improving the rubber performance, the tire vulcanization performance is further improved; the pumping noise is reduced by improving the tread pattern structure.
