Spitfire F4 Classic 55mm 99a Skateboard Wheels in the OG classic colourway for a time tested classic! Tested by Spitfire Team riders, Formula Four Performance Urethane lasts longer, withstands massive park abuse and performs superior to all other wheels.

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. 

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.

Bearing core -  Center-Set so you can reverse the wheel to save the graphic and help get longer life out of your wheels as you can rotated them so they burn down evenly.
