Abstract:
Disclosed is a rubber composition for protecting a sidewall of a tire from ozone and a tire manufactured using the same. More specifically, disclosed is a tire including a rubber sheet for preventing aging between a sidewall and a carcass, wherein the rubber sheet for preventing aging includes a rubber composition including 100 parts by weight of a base rubber, 20 to 60 parts by weight of carbon black, and 2 to 5 parts by weight of an amine-based anti-aging agent. The tire produced from the rubber composition has an effect of exhibiting significantly improved ozone resistance without changing a degree of blackness in terms of appearance.
