Spitfire Formula Four OG Classics 99D Wheels (54mm) Silver

Experience the perfect fusion of performance and heritage with the Spitfire Formula Four 99D O.G. Classics Skateboard Wheel — engineered for skaters who refuse to compromise.

Built on Spitfire's proprietary Formula Four urethane, this wheel sets the standard for durability and consistency. Unlike conventional urethane, Formula Four resists flatspotting, rolls faster, and maintains its shape session after session — so your ride stays as sharp on day 100 as it did on day one.

The 99D durometer hits the sweet spot for high-performance skating. Firm enough to generate speed and lock into grinds on street terrain, yet responsive enough to handle the transitions of park and vert — this hardness rating is a go-to choice among pros and serious skaters alike.

The legendary O.G. Classics shape is no accident. Decades of skating have proven this silhouette delivers maximum contact with the ground, giving you the confidence and control to push your limits on any surface.

Key Features:

• Formula Four urethane — flatspot-resistant, long-lasting, and fast-rolling
• 99D durometer — optimized for street, park, and vert skating
• O.G. Classics shape — time-tested design for superior grip and control
• Versatile performance — suitable for beginners through professional-level skaters

Whether you're learning your first kickflip or dialing in tech lines, the Spitfire Formula Four 99D O.G. Classics is the wheel that grows with you.
