Disclosed is a composition that enhances the mechanical properties of a compound, improves the tear behavior of a cured rubber compound, improves the polymer-filler interaction, and modifies the surface polarity of a tire tread compound. A polymer backbone derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer, for a pneumatic tire comprising at least one component; The functional group is a rubber composition containing a functionalized elastomer containing an oligopeptide or a functional group containing a modified oligopeptide, and as a tire tread, the surface polarity is modified to improve wet tire performance. Has a positive effect. [Selection figure] None |
