There is provided a pneumatic tire having improved wet grip performance and fuel efficiency in a good balance. The pneumatic tire is provided with a tread composed of a rubber composition comprising not less than 0.5 part by mass of silica and not less than 5 parts by mass of a resin based on 100 parts by mass of a rubber component comprising 40 to 100% by mass of a styrene-butadiene rubber and 0 to 60% by mass of a butadiene rubber, wherein an adhesive force of the rubber composition measured by the specified adhesion test method is not less than 300 when an adhesive force of a reference rubber composition wherein the whole amount of resin has been replaced by oil is assumed to be 100, and a ratio of a loss tangent tan δ0° C. at 0° C. of the rubber composition to a loss tangent tan δ70° C. at 70° C. of the rubber composition (tan δ0° C./tan δ70° C. is from 3.0 to 10.
