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.
