Provided is a cement rubber composition for a tire junction in tires for high-speed traveling, which shows excellent adhesive characteristics before and after vulcanization, and prevents the tread junction from splitting during high-speed traveling. The cement rubber composition for a tread junction in tires for high-speed traveling comprises: 100 parts by weight of styrene-butadiene rubber; 20-30 parts by weight of styrene-alpha-methylstyrene copolymer resin; and 30-60 parts by weight of an inorganic filler. Particularly, the inorganic filler comprises 20-30 parts by weight of carbon black and 10-30 parts by weight of silica. |
