Firestone 8663 Winterforce 2 225/55R18 98S Winter Snow Tire

The Firestone Winterforce 2 is a studdable winter/snow tire engineered for coupes, sedans, wagons, and minivans. Carrying the Three-Peak Mountain Snowflake (3PMSF) certification, it is purpose-built to deliver confident, reliable traction in cold, snowy, and icy conditions where all-season tires fall short.

The Winterforce 2 features a directional tread pattern molded from a special cold-weather rubber compound that remains pliable in freezing temperatures. Deep circumferential grooves, wide lateral slots, and open shoulder blocks work together to evacuate slush and standing water from the contact patch, helping resist hydroplaning on winter-wet roads.

• 3-Peak Mountain Snowflake (3PMSF) certified — meets severe snow service requirements
• Directional tread design with cold-weather compound for enhanced grip in freezing temperatures
• Full-depth tread features maintain winter performance throughout the life of the tire
