Spitfire
Spitfire is skateboarding’s most iconic wheel brand—but the flame head runs deeper than just urethane. Their gear, accessories, and apparel carry the same fire that fuels their wheels.
Urethane - Formula Four 99A: Spitfire released their new Formula Four wheels a few years ago now. The latest formula was designed for higher abrasion resistance. This means it is a little harder to flat spot. Formula Four 99A wheels are generally decorated with a blue themed graphic. Unless of course it is one of the signature wheels. The signature wheels feature artwork custom designed for each rider. 99A is considered a softer wheel in the modern skateboarding scene. They are still very hard. The 99A formula will provide a little more grip on super smooth surfaces and is a little more forgiving to ride on rougher surfaces..
