The invention provides a tire sidewall rubber composition, a tire sidewall rubber and a preparation method of the tire sidewall rubber, and relates to the technical field of tire manufacturing. The tire sidewall rubber composition is prepared from the following components in parts by weight: 100 parts of raw rubber, 10 to 45 parts of modified carbon nanotube/carbon black aggregate, 1 to 12 parts of active agent, 0.8 to 6 parts of accelerant, 0.8 to 6 parts of vulcanizing agent, 3 to 7 parts of anti-aging agent, 1 to 5 parts of environment-friendly oil, 1 to 4 parts of tackifying resin, 0.8 to 4 parts of tearing resin, 1.5 to 4 parts of protective wax, 0 to 25 parts of white carbon black, 0 to 2.5 parts of silane coupling agent and 0 to 0.3 part of scorch retarder. Wherein the modified carbon nanotube/carbon black aggregate is obtained by carrying out high-temperature jet flow on a modifier and a carbon nanotube/carbon black aggregate. According to the tire sidewall rubber composition disclosed by the invention, the modified carbon nanotube/carbon black aggregate is added, so that the mechanical property of the tire sidewall rubber is remarkably enhanced, heat generation is reduced, and abrasion is improved.
