Patent ID: 8256478

Claim:
A pneumatic tire having a designated tire inner side/outer side mounting orientation when mounted on a vehicle, comprising: at least two types of cap tread rubber layers made from differing rubber compositions disposed in a tread portion so as to be adjacent to each other in a tire width direction, wherein a tan δ at 60° C. of a rubber composition forming the cap tread rubber layer on a vehicle outer side is greater than a tan δ at 60° C. of a rubber composition forming the cap tread rubber layer on a vehicle inner side, a ratio (tan δH/tan δL) of a maximum tan δH to a minimum tan δL at 60° C. of the rubber compositions forming the at least two types of cap tread rubber layers is from 1.05 to 1.80, the hardness of the at least two types of cap tread rubber layers is the same at 20° C., an under tread rubber layer is disposed in the tread portion as a base for the at least two types of cap tread rubber layers, wherein an average thickness of the under tread rubber layer is from 0.8 mm to 4.0 mm, a hardness at 20° C. of a rubber composition forming the under tread rubber layer is from 73 to 83 and is greater than a hardness at 20° C. of the rubber compositions forming the at least two types of cap tread rubber layers, and a tan δ at 60° C. of the rubber composition forming the under tread rubber layer is 0.25 or less.
