About Spitfire Wheels

Founded in 1987 by pro skater Jim Thiebaud and entrepreneur Fausto Vitello in San Francisco, Spitfire quickly became a cornerstone of skateboarding. Known for durable, high-performance wheels and their iconic flaming skull “Bighead” logo, Spitfire helped define street and park skating in the late ‘80s and ‘90s.

Innovation has always been at the core of Spitfire. From early urethane formulas that resisted flatspotting to today’s Formula Four line—renowned for speed, smoothness, and longevity—the brand keeps pushing what skateboard wheels can do.

Part of Deluxe Distribution, Spitfire continues to roll with legendary pros and rising talent alike, creating wheels, graphics, and products that capture skateboarding’s raw, creative spirit. When you ride Spitfire, you’re rolling with heritage, performance, and that unmistakable fire under your board.
