The present invention provides to a rubber composition for a breaker topping including 15 to 50 parts by weight of carbon black and 5 to 50 parts by weight of silica based on 100 parts by weight of a rubber component (provided that a butadiene rubber containing 1,2-syndiotactic polybutadiene crystals is not included) including 10 to 45% by weight of a modified butadiene rubber and/or a modified styrene-butadiene rubber and 55 to 90% by weight of a natural rubber and/or an isoprene rubber for the purpose of improving low fuel cost while keeping rigidity, elongation at break and peel strength at high level.
