To provide a tire enhancing the on-ice performance without impairing the driveability on a dry road surface and wet road surface and reducing rolling resistance.
This tire is characterized by using a rubber composition comprising: 100 pts.mass of a rubber matrix containing at least one type of diene-based rubber selected from a group consisting of a natural rubber, a polyisoprene rubber, and a polybutadiene rubber and a high molecular weight-modified conjugate diene-based polymer having a weight average molecular weight before modification of more than 15×104 and 200×104 or less; 0.5 pt.mass or more and less than 100 pts.mass of a hydrogenated resin; 5 to 50 pts.mass of a low molecular weight-modified conjugate diene-based polymer having a weight average molecular weight before modification of 2×103 to 15×104; and 20 to 200 pts.mass of a reinforcing filler.
