  • TIRE WITH TREAD CONTAINING VEGETABLE OIL EXTENDED HIGH TG STYRENE/BUTADIENE ELASTOMER AND TRACTION RESIN
    Publication number: 20190225778
    Abstract: This invention relates to a tire with high performance tread of rubber composition for promoting tread durability and traction. For such purpose, a tread rubber composition is provided which contains a high Tg solvent solution polymerization prepared styrene/butadiene elastomer (SSBR) together with precipitated silica reinforcement and traction resin. The invention includes extension of the uncured high Tg SSBR by triglyceride vegetable oil instead of petroleum based oil.
