Zusammenfassung:	Provided are tires with excellent handling stability on ice and snow. Included is a tire which includes a cap tread and a base tread, and satisfies the following relationships (1) and (2): 0.4≦TcTb≦1.5 wherein Tc represents the average thickness of the cap tread, and Tb represents the average thickness of the base tread, and tanδcE∗c≧0.16 wherein tan δc represents the -30°C tan δ (the loss tangent measured at a temperature of -30°C, an initial strain of 10%, a dynamic strain of 2.5%, and a frequency of 10 Hz) of the cap tread, and Ec represents the 0°C E (the complex modulus measured at a temperature of 0°C, an initial strain of 10%, a dynamic strain of 2.5%, and a frequency of 10 Hz) of the cap tread.
