Document Type and Number:
WIPO Patent Application WO/2018/056382
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a rubber composition which is capable of improving steering stability and wet performance of a tire, while reducing rolling resistance thereof. Accordingly, this rubber composition is characterized by including: 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 rubber composition is further characterized in that: the storage elastic modulus (E'30˚C, 1%) at 30˚C and 1% strain is 4.5 MPa or higher; and the storage elastic modulus (E'0˚C, 4%) at 0˚C and 4% strain is 16.7 MPa or lower.
