Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composition for tire having excellent traction and acceptable tread wear resistance as a tire. SOLUTION: The invention relates to a pneumatic rubber tire having at least one component of a polybutadiene-rich rubber composition comprised of a blend of a continuous phase of a specialized cis 1,4-polybutadiene rubber and a dispersed phase comprised of a composite of styrene/butadiene elastomer which contains a dispersion of at least partially exfoliated, intercalated, clay platelets, wherein the cis 1,4-polybutadiene rubber and styrene/butadiene elastomer have spatially defined glass transition temperatures, wherein the blend contains amorphous silica and carbon black reinforcement. Such tire component may be, for example, a circumferential tread having a running surface intended to be ground-contacting or a sidewall insert. COPYRIGHT: (C)2005,JPO&NCIPI
