PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of achieving both wear resistance and low heat-generation property.SOLUTION: The pneumatic tire has a tread made of a rubber composition comprising a rubber component including isoprene rubber and high-cis butadiene rubber having 90 mass% or more of a cis content, at least one type of carbon black, and sulfur. At least one type of the above carbon black is obtained by using the following raw oil as a raw oil for producing the carbon black. The raw oil shows a BMCI value of 150 or less, which is calculated by formula of BMCI=48640/(T+273)+473.7D-456.8, where T (°C) represents an average boiling point and D (60/60°F) represents a specific gravity compared to water at 60°F, and an aliphatic hydrocarbon ratio of 30 mass% or more.SELECTED DRAWING: None |
