Abstract
A passenger vehicle tire in which tread rubber T07 is composed of cap rubber T07C and base rubber T07B. The cap rubber is positioned on the tire radial direction outer side with respect to the base rubber and is also positioned on both tire width direction outer sides with respect to the base rubber. The base rubber is composed entirely of rubber having the same composition. The tire width direction width of the base rubber is shorter than the tire width direction width of the cap rubber. The storage modulus E′ of the base rubber is at least 2.0 times the storage modulus E′ of the cap rubber.
