A bead filler rubber composition for tire is provided to improve processability by reducing viscosity without falling reinforcement property by applying having a low melting point and low molecular weight. A bead filler rubber composition for tire comprises a base rubber 100.0 parts by weight, carbon black 60~80 parts by weight and phenol resin 10~25 parts by weight. The phenol resin has a melting point 60~70 °C, the number average molecular weight 900~950 and the average molecular weight 6,000~7,000. The bead filler rubber composition further comprises additives such as an activator, sulfur, and a vulcanization accelerator. |
