Disclosed is a tire apex rubber composition. According to the present invention, the tire apex rubber rubber composition contains 5-30 parts by weight of polycarbonate with respect to 100 parts by weight of raw rubber. Owing to excessive amount of a reinforcing material used therein, heat-emitting properties of the rubber composition and durability of the tire decrease, and processability is also reduced as viscosity increases. By resolving an issue associated with reduction in mileage due to an increase in the weight, the weight is reduced, and harness increases, thereby improving handling performance, low heat-emission and low-rolling resistance (LRR).

    본 발명은 타이어 에이펙스 고무조성물를 개시한다. 본 발명에 따르는 타이어 에이펙스 고무조성물에 의하면, 타이어 에이펙스 고무조성물에 있어서, 원료고무 100중량부에 대하여 폴리카보네이트 5 내지 30 중량부를 포함하는 것을 특징으로 하는데, 이에 의할 때, 과량의 보강재를 사용함으로써 고무조성물의 발열특성이 하락하여 타이어의 내구성능이 하락하고, 점도 상승에 의한 공정성이 하락하며, 중량 증가에 따른 연비 하락을 해결하여, 중량을 낮춤과 동시에 강성을 증가시켜 핸들링 성능을 개선시키며, 저발열 및 LRR 성능을 향상시킬 수 있다.
