Spitfire Wheels Formula Four Radial Full Blue (55mm/99d) bring that unmistakable Spitfire look and proven performance together in a setup that’s built to handle real-world street skating. The bold blue graphic pops against the natural urethane, with Spitfire’s classic Bighead staring back through a clean, high-contrast print that holds up session after session. At 55mm, this size hits the sweet spot for skaters who want speed and stability without sacrificing responsiveness, making it ideal for everything from rough LA streets to smooth park concrete.
The Radial Full shape is all about control and consistency. With a wider riding surface and rounded outer edges, these wheels lock in confidently on ledges, rails, and fast approaches while still releasing clean when it’s time to slide. The 99d Formula Four urethane is Spitfire’s gold standard—fast on crusty pavement, predictable on smooth ground, and resistant to flatspots even after long days pushing through the SGV, whether you’re cutting through side streets in Pasadena, hitting schoolyard spots in Alhambra, or rolling out to parks around Covina and beyond.
Spitfire’s legacy runs deep, born from the same Deluxe Distribution lineage that shaped modern street skating. Formula Four changed the game by proving that a harder wheel could still grip when you need it and slide when you want it, and this Radial Full setup carries that torch forward with a shape trusted by pros and locals alike. Built for skaters who want durability, speed, and control without gimmicks, these wheels feel right at home under a board being pushed hard, filmed, and skated daily.
