RUBBER COMPOSITION AND PNEUMATIC TIRE USING THE SAME

摘要

Disclosed is a rubber composition comprising a rubber component and at least one of a terpene resin and a rosin resin in an amount of 0.5 part by mass relative to 100 parts by mass of the rubber component, wherein the rubber component contains a natural rubber component comprising at least one of a natural rubber and a modified natural rubber at a ratio of 20 to 100% by mass. Also disclosed is a pneumatic tire comprising the rubber composition. It becomes possible to provide: a rubber composition which uses a raw material derived from a petroleum resource in a reduced amount, can maintain the properties required for the intended use application and has improved processability; and a pneumatic tire using the rubber composition.
