| description | PROBLEM TO BE SOLVED: To provide a tire having superior on-ice performance and low rolling resistance without degrading wet steering stability and dry steering stability. SOLUTION: In the tire, the following rubber composition is used for a tread. The rubber composition contains: a rubber component containing a modified conjugated diene polymer rubber having both of a nitrogen atom-containing functional group and a silicon atom-containing functional group or a functional group having a nitrogen atom and a silicon atom, at a polymerization initiation end and/or a polymerization termination end; and with respect to 100 parts by mass of the rubber component, 5 to 50 parts by mass of a low molecular weight modified conjugate diene polymer having a weight-average molecular weight of 2×103to 15×104before modification; and 20 to 200 parts by mass of a reinforcing filler; and the rubber composition includes air bubbles in an amount of 5 to 50 vol.% as a bubble fraction in the rubber matrix after vulcanization.
