PROBLEM TO BE SOLVED: To provide a pneumatic tire which is satisfactorily improved in fuel economy, rubber breaking strength, and wear resistance while properly maintaining productivity.SOLUTION: The pneumatic tire is produced using a rubber composition. The rubber composition contains: a hydrogenated copolymer which has a constituent unit based on an aromatic vinyl compound and a constituent unit based on a conjugated diene compound and in which the hydrogenation rate of a conjugated diene moiety is 75 mol% or more; and a sulfur donor. The content of the hydrogenated copolymer is 75 mass% or more in 100 mass% of a rubber component, and the content of the sulfur donor is 0.2-8 pts.mass based on 100 pts.mass of the rubber component.SELECTED DRAWING: None
