The Spitfire Wheels Formula Four Conical Full Natural (58mm/97d) brings the heat for skaters who demand a stable ride and smooth, predictable slide. Built with Spitfire’s legendary Formula Four urethane, these wheels are flatspot-resistant, fast-rolling, and grippy when you need it—ideal for both crusty SoCal parking lots and polished transitions at places like Garvanza Skatepark. The Conical Full shape offers a wider riding surface (23.2mm) and greater overall width (35.6mm), giving you more control and less slip when locking in grinds or charging at full speed.

At 58mm, this size is perfect for all-terrain destruction. You’ll feel the extra meat underfoot without losing responsiveness—whether you're wallriding a handball court in El Monte or floating a backside air at Chino. The 97 durometer gives you just enough cushion for rougher terrain while still holding its shape through the sketchiest reverts. It’s the wheel shape of choice for riders who want that perfect blend of technical agility and bowl-ready confidence.

Spitfire has been holding it down since 1987, making top-tier urethane under DLX’s watchful eye in San Francisco. Known for their unmatched rider roster and relentless product testing, Spitfire continues to lead the pack with shapes and duros dialed to real-world skateboarding—not just catalog specs. The Conical Full is the workhorse of the line, preferred by tech destroyers and pool slayers alike.
