Spitfire Formula Four 93A Classics Wheels 54mm pair Formula Four 93A urethane with the Classic shape. Formula Four 93A Soft Sliders give a controllable, consistent slide anywhere. The softer duro and high-rebound compound absorb more impact and vibration, so they're easier on your body for longer sessions.

At 54mm x 33.6mm, with a 16.4mm riding surface, this mid size is the go-to for street and park. Sold as a set of 4.

FAQ

Is 93A hard or soft?

Softer than a standard street wheel. 93A gives a controllable slide while absorbing more impact and vibration.

What is the Classic shape good for?

All-around control. Spitfire describes it as the number one wheel shape in skateboarding: a medium-width riding surface with round sidewalls, designed for control in all situations.

What size wheels should I get?

Smaller wheels (50 to 52mm) are light and technical, 53 to 54mm is the street and park go-to, and 55mm and up adds speed for transition and rough ground. See our skateboard wheels guide for more.
