Rubber composition for tire and pneumatic tire using the same

The present invention provides a rubber composition of a tire and a pneumatic tire, in which friction on ice is improved. Specifically, the present invention relates to a rubber composition for a tire comprising 0.5 to 30 parts by weight of a filler having at least two protuberances based on 100 parts by weight of diene rubber, the average length of said protuberances being at least 10 mu m, and a pneumatic tire comprising the rubber composition for a tire.
