Rubber composition for tire tread, method for manufacturing tire tread using the same and tire manufactured by the method

PURPOSE: A rubber composition for a tire tread is provided to improve frictional coefficient on ice maintaining the properties of the rubber like strength, etc, and to use environment-friendly material. CONSTITUTION: A rubber composition for a tire tread comprises 100 parts by weight of a crude rubber, 5-40 parts by weight of rhodophyta crushed material. The average particle diameter of the rhodophyta crushed material is 0.50mm or less. A manufacturing method of a tire tread comprises: a step of removing and pulping impurities in the rhodophyta crushed material; a step of drying the pulped rhodophyta crushed material; a step of pulverizing the rhodophyta crushed material; and a step of mixing the rhodophyta crushed material and the crude rubber.
