Pneumatic tire

A pneumatic tire 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 following 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is not less than 300 when an adhesive force of a reference rubber composition wherein the whole amount of resin has been replaced by oil is assumed to be 100,
• a loss tangent tan δ70° C. at 70° C. of the rubber composition is not more than 125 when a loss tangent tan δ70° C. of the reference rubber composition is assumed to be 100, and
• a ratio of a loss tangent tan δ0° C. at 0° C. of the rubber composition to the loss tangent tan δ70° C. of the rubber composition (tan δ0° C./tan δ70° C. ) is from 3.0 to 10.
• <Adhesion Test Method>
• The adhesion test method comprises:
• a preparation step of preparing a test rubber,
• a friction test step of conducting a wet friction test and generating an adhesive substance on a surface of the test rubber,
• a step of measuring the adhesive substance wherein a volume of the adhesive substance and an adhesive force per unit area of the adhesive substance are measured, and
• an evaluation step of evaluating an adhesive force of the test rubber based on the volume of the adhesive substance and the adhesive force per unit area of the adhesive substance.
