Spitfire Formula Four OG Classic Wheels Natural/Yellow 99D - 55mm

The Spitfire Formula Four OG Classic Wheels in Natural/Yellow (55mm, 99D) deliver the performance that has made Spitfire a top choice for skaters worldwide. Built with Spitfire’s legendary Formula Four urethane, these wheels offer unmatched durability, flatspot resistance, and a consistent, smooth ride session after session.

The OG Classic shape features a proven, versatile design with a solid riding surface and slightly rounded edges, giving you the perfect balance between control and speed. At 55mm, they’re ideal for all-around street and park skating—fast enough to keep your lines flowing, while still responsive for technical tricks.

Finished in a clean Natural urethane with bold yellow graphics, these wheels bring classic Spitfire style backed by high-performance technology.
