Abstract:
The present invention can provide a rubber composition for a bead apex comprising 20 to 120 parts by weight of a silica and 5 to 80 parts by weight of a graphite on the basis of 100 parts by weight of a rubber component comprising a natural rubber in an amount of not less than 30% by weight, use of which makes it possible to consider an effect on environment, prepare for decrease in petroleum supply in future, and reduce rolling resistance and improve steering stability, and a tire prepared by using it.
