Abstract
Compositions of triazoles, such as benzotriazole or tolyltriazole, in silica reinforced rubber compositions for tire components and tires made of such compounds are provided exhibiting high cure rate, cure efficiency, hardness, static and dynamic moduli without deleteriously effecting hysteresis. Methods for optimizing silica reinforced tire properties utilizing triazoles, brass powder and carbon black are also provided. Typical tire compositions employ from about 2 to about 35 parts triazoles, and preferably from about 2 to about 6 parts triazoles, per hundred parts of rubber. In some compositions, brass powder and conductive carbon black are used in combination with the triazole in the rubber composition.
