Spitfire Formula Four Radial Full Wheels Natural 99D - 54mm

The Spitfire Formula Four Radial Full Wheels in Natural (54mm, 99D) are built for skaters who want maximum control, speed, and durability in every session. Made with Spitfire’s premium Formula Four urethane, these wheels are known for their long-lasting performance, resistance to flatspots, and consistent slide—session after session.

The Radial Full shape features a wider riding surface and fuller profile, giving you extra stability and more contact with the ground. This means better control on landings, smoother power slides, and more confidence at higher speeds. At 54mm, these wheels strike a perfect balance for technical street skating while still handling ramps and transitions with ease.

With a 99D durometer, you get a responsive, fast-rolling wheel that slides when you want it to, without sacrificing grip when you need to stay locked in.

Finished in classic Natural urethane, these wheels keep it clean and timeless, backed by Spitfire’s reputation for top-tier performance.
