PURPOSE: A pneumatic tire is provided to improve wear characteristics and wet skid resistance and to lower rolling resistance. CONSTITUTION: A pneumatic tire comprises a component with a vulcanizable rubber composition. The component comprises rubber polymer about 60 to 90phr, polybutadiene about 40 to 10phr, and silica about 50 to 150phr based on elastomer 100 phr. The vulcanizable rubber composition comprises silica about 50 to 100 phr. The component is one of a tread cap, a tread base, a sidewall, an apex, a chafer, a sidewall insert, a wire coat, and an inner liner.
