Patent ID: 7919560

Claim:
A studless tire comprising a tread produced from a rubber composition, comprising: a rubber component containing natural rubber and butadiene rubber; and hydrogenised liquid polybutadiene, wherein the total amount of the natural rubber and the butadiene rubber is 80% by weight or more based on 100% by weight of the rubber component, the amount of the hydrogenised liquid polybutadiene is 1 to 60 parts by weight based on 100 parts by weight of the rubber component, the average molecular weight of the hydrogenised liquid polybutadiene is 600 to 20,000, the hydrogenization ratio of the double bond of the hydrogenised liquid polybutadiene is 20 to 60%, and a peak temperature of tan δ of the rubber composition is at most −45° C. and rubber hardness of the rubber composition at 0° C. is at most 64.
