RUBBER COMPOSITION FOR USE IN TIRES, AND PNEUMATIC TIRE

摘要

Provided are: a rubber composition for use in tires, said rubber composition providing improved fuel efficiency, wet-grip performance, and abrasion resistance; and a pneumatic tire using said rubber composition. Said rubber composition contains: a rubber component containing a modified styrene-butadiene rubber, the main chain of which has a constitutional unit derived from a specific nitrogen-containing compound; silica; and a specific silane coupling agent.
