Document Type and Number:
WIPO Patent Application WO/2017/209264
Kind Code:
A1
Abstract:
The present invention provides a rubber composition which is capable of improving fuel consumption saving performance, wet performance and wear resistance of tires, and which is characterized by containing a rubber component (A) that contains 55% by mass or more of a polybutadiene rubber, a thermoplastic resin (B) and a filler (C). This rubber composition is also characterized in that: the blending amount of the thermoplastic resin (B) is 5-40 parts by mass relative to 100 parts by mass of the rubber component (A); the tan δ at 0°C is 0.5 or less; and the difference between the tan δ at 30°C and the tan δ at 60°C is 0.070 or less.
