Spitfire Formula Four 99D Wheels
Formula Four is Spitfire's flagship performance urethane, developed and tested by Spitfire team riders until it outlasted and outperformed every other wheel they tried. The 99D durometer strikes a balance for skaters who want speed and grip without giving up control.
What Makes Formula Four Different
- More speed and control across all surfaces
- Unmatched flatspot resistance for wheels that keep their round shape longer
- Smooth anti-stick slide when you need to break traction
- High rebound compound for a lively, responsive feel
- 100% true performance urethane, not a blended or recycled formula
Built From Combined Qualities, Not One Trick
Rather than chasing a single benefit, Spitfire engineered Formula Four so speed, grip, and durability all work together, so upgrading your wheels does not mean sacrificing one attribute for another.
From a Skate-First Company
Spitfire was founded in 1987 by Jim Thiebaud and has since expanded into bearings, skateboard tools, griptape, and soft goods, but wheels remain the brand's proving ground.
