Abstract
This invention relates to a silica reinforcement-containing rubber composition which contains a functionalized polybutadiene rubber to promote a relatively low hysteretic loss to thereby enhance its desirability for tire sidewall and subtread applications in a sense of advantageously promoting reduced tire rolling resistance without significantly compromising various other desirable tire performance parameters.
