My car came with new Michelin Tires from the factory. They were HORRIBLE during the winter. Replaced with Goodyear Eagle GT Tires, and experienced much improvement. Tried Pirreli Winter Sotto Zero 3 Tires, and never knew tires could have that much of a dramatic, positive affect. The Pirelli Tires provided a dramatic improvement in all areas, in all seasons. HOWEVER, my next set of tires will be the Assurance Goodyear Triple Tread All Season Tires. This change will be based solely on looks. These particular Goodyear tires have a more aggressive, and squarish appearance in shape compared to the oval look of the Pirreli Tires.
