摘要：
The invention relates to preparation of a high silica reinforcement-containing rubber composition by a method which involves a delayed and divided inclusion of greater than 50 percent of fatty acid salt processing aid to a rubber composition in an internal rubber mixer following completion of addition of precipitated silica and silica coupling agent in a preceding rubber mixing step in an internal rubber mixer. The invention further relates to a resulting rubber composition and to tires having a component thereof such as, for example, a tire tread.
