BFGOODRICH g-Force COMP-2 A/S All_Season Radial Tire-215/045R17 91W UltiGrip Technology: 1) Large, rigid tread blocks optimize rubber-to-road contact for ultimate dry grip. 2) Consistent tread block rigidity balances acceleration forces within the tire footprint. Performance Racing Core: ETEC System (TM) Equal Tension Containment System optimizes the contact patch for enhanced traction at speed. UltiGrip Technology: 1) Optimized rubber-to-road contact for ultimate dry grip 2) All-season compound designed for the best wet and dry grip.g-Force (TM) Tread: 1) Squared-off shoulder and enhanced contact patch shape evenly distributes stresses across the footprint. 2) Performance Tread Profile resists irregular wear typically associated with directional tread designs. UltiGrip Technology: 1) High-silica, cold-weather flexing compound for best wet and dry grip and all-season traction. 2) V-shaped angled lateral and longitudinal grooves efficiently evacuate water for better wet traction. 3) High-lateral void with beveled biting edges and wide lateral grooves improve snow retention and adherence for greater mobility during winter. Dynamic Suspension System (DSS) is a reinforced internal structure that increases control while maintaining ride comfortg-Control (TM) Sidewall Inserts add sidewall stiffness to resist deflection for immediate turning response.Performance Tread Profile for ultimate grip in hard cornering, and a bold performance look.
