Spitfire Classic Formula Classics Wheels 55mm are Classic Formula 99A wheels in the Classic shape, built for all-around control. Spitfire's original Classic 99 Duro formula is the one that started it all: fast and smooth, with a speed-controllable slide when you need it.

At 55mm x 34.6mm, with a 17.3mm riding surface, this size adds a little speed and roll for park and transition. Sold as a set of 4.

FAQ

Is 99A hard or soft?

Hard. 99A is the standard street and park hardness: fast, with a controllable slide.

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.
