RUBBER COMPOSITION AND PNEUMATIC TIRE

摘要

The present invention provides: a rubber composition which is capable of improving fuel consumption saving, wet grip performance and wear resistance in a balanced manner; and a pneumatic tire which uses the rubber composition. The present invention relates to a rubber composition which contains a rubber component, silica and a liquid resin having a softening point from -20°C to 20°C. In the rubber composition, 5% by mass or more of a conjugated diene polymer, which has a constituent unit derived from a conjugated diene and a constituent unit represented by formula (I) and at least one end of which is modified with a specific compound, is contained in 100% by mass of the rubber component, and the silica is contained in an amount of 5-150 parts by mass per 100 parts by mass of the rubber component.
