Abstract

Provided is a pneumatic tire using a rubber composition which makes it possible to keep rolling resistance low, prevent the accumulation of static electricity during the running of the tire, suppress an increase over time in electrical resistance of the tire, and improve durability. The present invention relates to a rubber composition, including: a rubber component including two or more diene rubber; and carbon black having a nitrogen adsorption specific surface area of 400 m<2>/g or more in an amount of 5 to 30 parts by mass per 100 parts by mass of the rubber component, wherein the rubber composition has a degree of carbon black dispersion determined by counting agglomerates based on JIS K 6812 "Method for the assessment of the degree of pigment or carbon black dispersion in polyolefin pipes, fittings and compounds" of 90% or more.
