SPITFIRE FORMULA FOUR APRIL BIGHEAD ROSE RADIAL 54MM 99D (Set of 4)

The Spitfire x April "Bighead Rose" wheels bring April Skateboards styling to Spitfire's industry-leading Formula Four urethane. This official collaboration combines Spitfire's iconic Bighead identity with an exclusive rose graphic treatment, finished in a standout marbled swirl colorway that no two sets wear exactly alike. Formula Four is the pro standard for a reason: more speed and control on every surface, unmatched flat-spot resistance, a smooth anti-stick slide, and a high-rebound compound that keeps its shape and speed session after session. Every set is hand-poured and engineered in San Francisco, CA.

At 54mm, these run the Radial shape — rounded sidewalls with a generous riding surface for a stable, locked-in feel and confident control. It's the do-everything street and park size: low and light enough for technical flip tricks and ledges, with enough roll to keep your speed up. The 99a durometer is the versatile sweet spot: fast and slidey like a harder wheel, but forgiving enough for everyday terrain. Sold as a set of four.
