PROBLEM TO BE SOLVED: To provide a rubber composition for a chafer improving low heat buildup (low fuel consumption) and rubber strength (tear strength) with good balance and a pneumatic tire using the same. SOLUTION: The rubber composition for a chafer contains a rubber component containing butadiene rubber modified with a compound represented by a specific formula, silica, and a silane coupling agent represented by a specific formula and/or a silane coupling agent comprising a bonding unit A represented by a specific formula and a bonding unit B represented by a specific formula.
