The invention discloses a damping and noise-reducing solid tire and a preparation method thereof, and relates to the technical field of damping and noise-reducing solid tires. Center pattern blocks (8), side pattern blocks (10) and filling pattern blocks (11) are regularly distributed on a tread (2) of the tire body (1), side holes (13) are circumferentially distributed in the second tire side area (4) with the center line of the tire body (1) as the axis, the side holes (13) are inclined taper holes, and open hole circles exposed on the tire side are small circles of the side holes (13). Compared with the prior art, the solid tire has the beneficial effects that the method of adding the hollow inorganic particles into the polyurethane material of the solid tire and improving the structureof the solid tire is adopted, the tread is provided with the pattern blocks, the tire side wall is provided with the side holes, the vibration of the solid tire can be effectively reduced, and the noise is reduced by 2-8 dB.
