PROBLEM TO BE SOLVED: To provide a pneumatic tire achieving both wet grip performance and abrasion resistance at a high level.SOLUTION: There is provided a pneumatic tire with a tread part constituting a rubber composition comprising 110 to 200 pts.wt. of silica blended with 100 pts.wt. of diene rubber wherein the rubber composition satisfies (a) the tanδ of the rubber composition at 0°C is over 1.02 and (b) the minimum size of an aggregate forming a hierarchical structure of the silica Ris over 14 nm and less than 27 nm when a scattering profile measured and obtained by an ultra small angle X-ray scattering method fits the Unified-Guinier function.SELECTED DRAWING: None |
