TIRE TREAD RUBBER COMPOSITION AND PNEUMATIC TIRE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a tire tread rubber composition having more excellent on-ice frictional force and wear resistance than those by conventional techniques, and to provide a pneumatic tire using the same. SOLUTION: The tire tread rubber composition is obtained by blending 100 pts.mass of a rubber component with 1-40 pts.mass of an oil solidified preliminarily with a solidifying agent such as a triglyceride derived from a fatty acid containing≥70 mass% of at least one selected from the group consisting of ricinoleic acid and 12-hydroxystearic acid. The pneumatic tire uses the rubber composition in the tread (3). COPYRIGHT: (C)2011,JPO&INPIT
