RUBBER COMPOSITION FOR TIRE TREAD AND PNEUMATIC TIRE

摘要

PROBLEM TO BE SOLVED: To overcome difficulties for satisfying various properties such as high grip performance, durability and abrasion resistance which are performances required for a racing tire at same time.SOLUTION: The above described problem is solved by a rubber composition for tire tread by blending 100 pts.mass of (A) a diene rubber containing an aromatic vinyl-conjugated diene rubber having Tg of -35°C or more, 50 to 200 pts.mass of (B) carbon black having (NSA) of 100 to 400 m/g and DBP absorption amount of 100 to 200 cm/100 g and 0.5 to 20 pts.mass of (C) a styrenated phenol compound mainly containing distyrenated phenol or tristyrenated phenol.SELECTED DRAWING: None
