RUBBER COMPOSITION FOR TIRE TREAD AND TIRE MANUFACTURED BY USING THE SAME

摘要

The present invention relates to a rubber composition for a tire tread and a tire manufactured by using the same. The rubber composition for a tire tread comprises: 100 parts by weight of raw rubber; 5 to 20 parts by weight of liquid butadiene rubber having an end group modified with siloxane (-Si(OCH_2CH_3)_3); and 5 to 15 parts by weight of liquid butadiene rubber having glass transition temperature (Tg) of -110 to -80°C. The rubber composition can improve braking performance on icy and snowy roads and wet roads, and can minimize loss of rotation resisting performance.
