Beschreibung
Zusammenfassung:	The present disclosure provides a rubber composition that can improve the steering stability and the wet performance of a tire while reducing the rolling resistance of the tire. The rubber composition includes a rubber component (A) including a natural rubber (A1) and a modified diene rubber (A2) having a glass transition temperature (Tg) of -50°C or lower, and a thermoplastic resin (B). The storage modulus of the rubber composition at 30°C under 1% strain (E',) is 4.5 MPa or more, and the storage modulus of the rubber composition at 0°C under 4% strain (E',) is 16.7 MPa or less.
