The present invention also provides a studless winter tire including a base tread which exhibits a reduced increase in hardness at low temperatures and achieves a balanced improvement in both performance on ice and snow and durability. The studless winter tires include a tread or base tread formed from a rubber composition that contains predetermined amounts of silica and a rubber component including natural rubber and a specific modified conjugated diene polymer.",
