The Spitfire Formula Four Conical Full Wheels in 53mm 99D are built for skaters who want maximum control, stability, and speed. Featuring Spitfire’s industry-leading Formula Four urethane, these wheels deliver unmatched flatspot resistance, smooth slides, and long-lasting performance.

The Conical Full shape offers a wider riding surface and fuller profile, providing increased stability and better control at higher speeds. The conical cut sidewalls help reduce weight while maintaining a strong contact patch, giving you a responsive feel without sacrificing grip.

At 53mm, this size is ideal for all-around skating, making it perfect for street, park, and transition. The 99D durometer delivers a balanced blend of grip and slide, giving you confidence across different terrains.
