Spitfire Wheels Formula Four Radial Full Swirl (56mm/99d) brings that unmistakable Spitfire energy with a wild, eye-catching swirl graphic wrapped around their proven Formula Four urethane. The multi-color swirl treatment makes every set slightly unique, layered over Spitfire’s classic Bighead artwork for a look that pops whether you’re pushing through Old Town Monrovia, rolling curb spots in Arcadia, or cruising longer lines around Pasadena and Alhambra. At 56mm, this size hits the sweet spot for skaters who want a little extra roll speed and stability without sacrificing responsiveness, making it ideal for rougher streets, fast park runs, and all-terrain sessions around the SGV.
Built with Formula Four 99d urethane, these wheels are designed to resist flatspots, maintain consistent slide, and hold speed far longer than standard formulas. The Radial Full shape features a wider riding surface with rounded edges, giving you a smooth, predictable feel on landings and a locked-in slide that snaps back clean every time. You’ll notice the control immediately—whether you’re powering through ledges, blasting hills, or dialing in technical tricks at your local. The natural core and precision-cut profile keep the wheel strong, fast, and reliable, session after session.
Spitfire has been setting the standard for skateboard wheels since the late ’80s, and Formula Four remains the gold benchmark worldwide. Trusted by generations of skaters, this Radial Full Swirl version blends performance and personality, perfect for riders who want their setup to stand out while still delivering top-tier function.
