Rubber composition and tyre tread.

摘要

The present invention provides a rubber composition which is useful for the treads of studless tyres which provide improved grip properties on frozen roads and maintain such performance for long use. The rubber composition comprises a base rubber and an inorganic halide which has a melting point of 180 DEG C or more, an average particle size of 20 to 600 micrometer and a solubility of 5 g or more in 100 g of water at 0 DEG C; said inorganic halide being present in an amount of 3 to 35 parts by weight based on 100 parts by weight of said base rubber.
