Firestone 8660 Winterforce 2 225/40R18 92S XL Winter Studdable Passenger Tire

The Firestone Winterforce 2 (225/40R18 92S XL) is a dedicated winter/snow tire engineered for coupes, sedans, wagons, and minivans. Built to handle the harshest cold-weather conditions, this tire delivers confident traction on snow, ice, slush, and cold dry pavement where all-season tires fall short.

Its directional V-shaped tread pattern channels slush and water away from the contact patch efficiently, while deep tread grooves, wide notches, and open shoulder slots maximize snow and slush evacuation. Thousands of tread sipes create additional biting edges for enhanced grip on packed snow and ice.

The special cold-weather rubber compound is formulated to remain pliable and responsive even in extreme cold, maintaining grip when standard rubber compounds stiffen and lose effectiveness. Full-depth tread features ensure long-lasting winter performance season after season.
