A pneumatic tire having a tread manufactured using a predetermined rubber composition and having greatly improved wear resistance while maintaining good wet grip performance and durability. An oil-extended butadiene rubber having a cis content of 95 mol% or more, a vinyl content of 1 mol% or less, and a weight average molecular weight of 530,000 or more, an isoprene-based diene rubber and / or a styrene butadiene rubber, and a nitrogen adsorption specific surface area of 110 to 200 m. 2 / g of carbon black and stearic acid, and the oil-extended butadiene rubber is a butadiene rubber synthesized using a rare earth element-based catalyst, and the oil-extended butadiene is contained in a total rubber solid content of 100% by mass. The content of butadiene rubber contained in the rubber is 8 to 65% by mass, the content of the isoprene-based diene rubber and / or styrene butadiene rubber is 20 to 85% by mass, and the total carbon solid content is 100 parts by mass. The black content is 20 to 100 parts by mass, the stearic acid content is 1.5 to 2.99 parts by mass, Amount of Rosesuoiru is a pneumatic tire having a tread produced from the rubber composition is not more than 9 parts by mass of the total rubber 100 parts by weight of solid content.
