The invention discloses a low-noise tire and a preparation method thereof, the low-noise tire comprises diene rubber, silicon dioxide particles, polylactic acid particles, sulfur and a vulcanization accelerator, and the average particle size of the polylactic acid particles is 40-60 microns. The rubber composition adopted by the tire contains polylactic acid particles and silicon dioxide particles with specific sizes, so that the noise of the tire is remarkably reduced, and the fuel economy and the wear resistance of the tire are improved.
