SPITFIRE FORMULA FOUR ENGINE 29 SFFD CONICAL FULL 54MM 99D (Set of 4)

Elevate your street and park game with the Spitfire Formula Four Engine 29 Conical Fulls. Engineered for performance and tested by the pros, these wheels offer the perfect balance of control, speed, and durability.

High-Performance Urethane

Built with Spitfire’s legendary Formula Four (F4) 99D durometer urethane, these wheels provide unmatched abrasion resistance. This means more speed and fewer flat spots, even after the heaviest power slides.

The Conical Full Shape

The Conical Full profile features a wide riding surface and cut-away sides. This design reduces weight while providing a massive contact patch for maximum grip and stability on transitions, rails, and rougher street surfaces.
