A rubber composition for tire treads is provided to realize production of low-weight tire treads and improved reinforcing property derived from porous zeolite, and to impart eco-friendly characteristics. A rubber composition for tire treads comprises 100 parts by weight of base rubber, and 45-70 parts by weight of nanoporous zeolite as a reinforcing agent. The zeolite has a nanopore size of 0.3-1.3 nm. The rubber composition optionally further comprises 50 parts by weight or less of silica or carbon black as a reinforcing agent based on 100 parts by weight of the base rubber. |
