Abstract

Provided are winter tires having excellent ice braking performance. Included are winter tires including a tire component containing a rubber composition, the rubber composition satisfying the following relationships (1) and (2) : 0.65≤tan δ at−30°C≤1.10 and 0.14≤tan δat−30°C/E*at0°C≤0.40 wherein the tan δ at -30°C represents the tan δ at -30°C under the shear mode conditions below, and the tan δ at -30°C and the E* at 0°C represent the tan δ at -30°C and the E* at 0°C, respectively, under the elongation mode conditions below:[Shear mode]Stress: 0.2 MPa,Frequency: 10 Hz,tan δ measurement temperature: -30°C;[Elongation mode]Elongation strain: 2.5%,Frequency: 10 Hz,tan δ measurement temperature: -30°C,E* measurement temperature: 0°C.
