Spitfire Formula Four Classic Yellow Purple Swirl 55mm 99a Skateboard Wheels are a new colourway for time tested classic! Tested by Spitfire Team riders, Formula Four Performance Urethane lasted longer, withstood more abuse and performed superior to all other wheels. Spitfire Formula Four Urethane was developed to combine all the desired properties of a performance wheel without sacrificing any one attribute at the expense of another. Formula Four's True lasting Performance Urethane comes not from a single benefit, but from a combination of qualities and features that together produce a truly great wheel Formula Four Performance Urethane is unlike any other.

Wheel Size -  The 55mm size will give you consistent speed for faster street skating while also maintaining a solid roll on the flat and better momentum on medium to large transition and ramps. 55mm is really the perfect size if you want to go big but not too big. 

Wheel Shape / Profile: Classic - Spitfire claim this is the #1 shape in skateboarding world wide. And it probably is. This shape first emerged in the early 90’s and has been a popular go-to ever since.  It features a large radius from the bearing seat which produces a fairly narrow contact patch. It is the great all rounder. For more info read Spitfire Wheel Shapes Explained

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.. For more info read Spitfire Wheel Formulas Explained

The bearing core is center-set so you can reverse the wheel to save the graphic or to maintain a longer life by rotating your wheel placement over the life of the wheel. This is handy when you slide your wheel often particularly in urban terrain that can wear your wheels in an uneven way.
