SPITFIRE - FORMULA FOUR 99D RADIAL FULL (58MM) - BLACK
The Spitfire Formula Four (F4) Radial Full in 58mm is a powerhouse wheel designed for high-speed stability and maximum control. Featuring the specialized Radial Full shape, these wheels combine the rounded edge of a classic radial with a wider, functional riding surface. At 58mm, this is a heavy-duty wheel optimized for transition, vert, and all-terrain cruising, providing a higher top speed and a smoother ride over cracks and rough pavement.
Engineered with Spitfire’s world-renowned 99D Formula Four urethane, these wheels offer the perfect balance of grip and slide. The 99D durometer provides a slightly more forgiving feel on slick concrete parks and crusty street spots compared to the 101D, while maintaining elite flat-spot resistance.
