Patent ID: 10907034

Abstract:
Provided is a pneumatic tire achieving a balanced improvement of steering stability, fuel economy, and processability. The pneumatic tire is formed from a rubber composition which includes: a rubber component; a plasticizer component; and a filler component. The rubber component includes: a diene rubber; and a copolymer containing an aromatic moiety as a structural unit derived from an aromatic vinyl compound and an ethylene moiety as a structural unit derived from ethylene. The ethylene moiety is present in an amount of 15 to 70% by mass based on 100% by mass of the total structural units of the copolymer excluding the aromatic moiety. The copolymer is present in an amount of 5 to 60% by mass based on 100% by mass of the rubber component. The rubber composition satisfies the following relationship: B/A=0.45 to 0.65.
