The invention relates to the technical field of rubber materials, in particular to a self-cleaning tire sidewall rubber composition and a preparation method thereof and a tire, and the self-cleaning tire sidewall rubber composition comprises the following raw materials in parts by weight: 60-80 parts of environment-friendly natural rubber, 30-72 parts of modified white carbon black wet-process natural rubber, 2-5 parts of modified TPE, 2-4 parts of modified EVA and 5-9 parts of a self-cleaning softener. 2-8 parts of zinc oxide, 3-5 parts of stearic acid, 3-7 parts of an anti-aging agent, 1-3 parts of an accelerant, 1-3 parts of a vulcanizing agent and 3-7 parts of activated non-polar metal pigment. According to the colored tire, the problem that an existing colored tire is prone to pollution in use, especially in rainy and snowy weather is solved, the possibility that the colored tire can be self-cleaned is achieved, and meanwhile the tire sidewall has better flex cracking resistance and higher strength and tear resistance.
