ABSTRACT:
An improved pneumatic tire having decreased rolling resistance employing at least one tire component selected from the group consisting of subtreads, black sidewall, body ply skims and bead fillers, prepared from a vulcanizable elastomeric composition having reduced hysteresis comprises from about 10 to 100 parts by weight of an elastomer comprising a plurality of polymer molecules, wherein substantially each polymer molecule contains at least one functional group at the site of initiation, and having a hysteresis reduction of at least about 10 percent compared to the same elastomer without a functional group on substantially each polymer molecule; from about 0 to 90 parts by weight of an elastomer having greater hysteresis than the elastomer having reduced hysteresis and selected from the group consisting of natural rubber, synthetic rubber and blends thereof; and, from about 20 to about 100 parts by weight of carbon black, per 100 parts of the elastomer. A method is also provided for reducing the rolling resistance of tires.
