Provided is a cold weather tire achieving a balanced improvement in fuel economy, abrasion resistance, performance on ice and snow, and high-speed performance (handling stability, grip performance) on snow- and ice-free roads at low temperatures. The cold weather tire includes a cap tread formed of a rubber composition that contains: a rubber component including polybutadiene rubber, styrene butadiene rubber, and natural rubber and/or polyisoprene rubber; and a filler, the rubber composition having a combined amount of the natural rubber, polyisoprene rubber, and polybutadiene rubber of 80% by mass or more, an amount of the polybutadiene rubber of 30% by mass or more, and an amount of the styrene butadiene rubber of 0.3-10% by mass, each based on 100% by mass of the rubber component, the filler including 60% by mass or more of silica based on 100% by mass of the filler, the cap tread having cells and/or voids.
