A tire rubber composition with excellent appearance characteristics according to the present invention includes an anti-aging agent represented by the following chemical formula 1 in a tire compound. The amount of the anti-aging agent is adjusted according to the shrinkage rate of the raw rubber of the tire compound. According to the present invention, the amount of the anti-aging agent and wax used is adjusted in consideration of the shrinkage stability according to the shrinkage rate of the tire. Therefore, the blooming phenomenon of the rubber is improved and the blackness is enhanced, so that the excellent quality of the tire appearance can be maintained for a long period of time.

    본 발명에 따르는 외관 특성이 우수한 타이어고무조성물 및 그 타이어 본 발명에 따르는 외관 특성이 우수한 타이어고무조성물 및 그 타이어는 타이어 배합물에 하기 화학식 1로 표기되는 노화방지제를 포함하고, 상기 타이어 배합물의 원료고무 수축율에 따라 상기 노화방지제의 배합량을 조절하는 것을 특징으로 하는데 이에 의하면, 타이어의 수축율에 따른 수축안정성을 고려하여 노화방지제, 왁스의 사용량을 조절함으로써 고무의 백화현상(Blooming)을 개선시키고 흑색도를 향상시켜 타이어 외관의 우수한 품위를 장기간 지속하고 유지시킬 수 있다.
