There is provided a rubber composition for a tyre tread having a remained despersibility of reinforcing agents without increased rubber hardness, an improved performance on sow and ice road, and an improved abrasion resistance, and inhibited from increasing in hardness or inhibited from increasing in hardness with the passage of time. A rubber composition for a tyre tread, which comprises (a) a diene rubber, (b) glass fibres, (c) a reinforcing agent, and 1 to 15 parts by weight of (d-1) inorganic powders having a Mohs hardness of less than 6.5 and an average particle size of less than 25 mu m and/or (d-2) silicone rubber powders based on 100 parts by weight of the diene rubber. |
