The invention provides a novel tire and a preparation method thereof. The novel tire comprises a presulfurized tire body, presulfurized tire tread rubber and middle cushion rubber. The middle cushion rubber is arranged between the presulfurized tire body and the presulfurized tire tread rubber, and the presulfurized tire body, the middle cushion rubber and the the presulfurized tire tread rubber are bonded and sulfurized together. The preparation method of the novel tire is that the middle cushion rubber, and the presulfurized tire body and the presulfurized tire tread rubber are bonded together, molded and sulfurized, so that the novel tire is made, wherein the sulfurization temperature is approximately 90-120 DEG C, the sulfurization pressure is approximately 0.5-0.7 MPa, and the sulfurization duration is determined according to the thickness of the tread rubber and the sulfurization speed of the middle cushion rubber. By applying the novel tire and the preparation method thereof, the structure of the existing traditional novel tire and the manufacturing method thereof are changed, the problem of uneven sulfurization of tires having thick patterns is solved, the physical and mechanical properties of the novel tire are improved, the service life is prolonged, the wear resistance and puncture resistance are superior to the traditional novel tire, the use cost of the tire is reduced, the difficulty in the tire manufacturing technology in huge engineering is lowered, and richer tire pattern styles are conveniently provided.
