Abstract: A tire tread and a pneumatic tire including the tread are described. The tread is formed from a vulcanizable rubber composition, which includes 50-70 phr of polybutadiene rubber, 30-50 phr of a solution-polymerized styrene butadiene rubber with a styrene content of 5-15 wt. % and a Tg of ?70° C. to ?50° C., at least 100 phr of silica, at least 6 parts by weight per hundred parts of the silica of an organosilane coupling agent, at least 2 phr of processing oil, at least 40 phr of resin, the resin including a hydrocarbon traction resin and a tackifier resin, and a cure package including a sulfur-based curing agent, zinc oxide, and a cure accelerator. The rubber composition provides the tire with a good balance of wet, dry, and cold performance characteristics.

Abstract: It has been found that a pneumatic tire comprising non-ground contacting tire components each independently formed from a rubber composition comprising greater than 89% sustainable material content can be manufactured. In one scenario the pneumatic tire is comprised of bio-renewable organic materials, wherein the bio-based content of the organic materials is verifiable, and wherein radiocarbon 14C dating according to ASTM method D6866 shows the level of bio-based content of the organic materials to be at least 40%. In a preferred embodiment the tire has an RFID tag affixed to the innerliner of the tire, wherein the RFID tag designates the level of bio-renewable organic materials in the tire.
