Abstract:
The object of the present invention is to provide a rubber composition suitable for a studless tire, which can inhibit rubber hardness increase with time and reveals excellent performance on ice and snow for a long time. The present invention relates to a rubber composition comprising 1 to 60 parts by weight of hydrogenized liquid polybutadiene based on 100 parts by weight of a rubber component containing at least 80% by weight of a natural rubber and a butadiene rubber, wherein a peak temperature of tan δ is at most 45° C. and rubber hardness at 0° C. is at most 64.
