摘要: Provided are: a rubber composition for studless winter tires, which is capable of improving on-ice/on-snow performance, wet grip performance and wear resistance in balanced manner; tire has tread that produced using the tires. The present invention relates to contains component containing natural butadiene rubber, an aroma oil, silica carbon black. The total content 100% by mass 30% or more; 12-85 parts oil contained per 100 component; black 45% more. One more kinds (1) having nitrogen adsorption specific surface area m 2 /g less one (2) 180 are as silica. 30-150 component, satisfy formula shown below. [Content (1)] × 0.2 ≤ [Content (2)] 6.5
