Abstract:
A pneumatic tire with superior durability having a tread part comprising a cap tread layer (layer A) and an under tread layer (layer B), wherein, in the pneumatic tire, when storage elastic moduli of the rubber compositions constituting the layer A and the layer B are designated as EA and EB, the storage elastic moduli EA (60° C.) and EB (60° C.) determined at a temperature of 60° C. satisfy the following formulae (1) and (2): EA(60° C.)/EB(60° C.)≦0.66 (1) 10(MPa)≦EB(60° C.) (2)
