    摘要: A pneumatic tire has a pair of sidewalls overlying a carcass connecting a pair of bead components and a rubber chafer adjacent to each sidewall, the chafer including 100 parts by weight of elastomer; 20 to 60 phr of a low surface area carbon black having an Iodine absorption value of from about 10 to about 50 g/kg; 20 to 60 phr of a high surface area carbon black having an Iodine absoption value of from about 100 to about 300 g/kg, each sidewall including 100 phr of the same elastomer used in the chafers; 20 to 60 phr of the same low surface area carbon black used in the chafers; 10 to 20 phr of the same high surface area carbon black used in the chafers, the weight ratio of high surface area carbon black in the chafers to high surface area carbon black in the sidewalls being greater than 1.
