Abstract
The present invention provides a rubber composition which is useful for the treads of studless tires which provides improved grip properties on frozen roads and preserves good performance after being used for a long period of time. The rubber composition of the present invention comprises a base rubber and an inorganic halide which has a melting point of 180.degree. 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.degree. 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.
