Wheel Profile

Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.


Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.

Key Features

Formula Four Urethane - Unmatched abrasion resistance for fewer flat spots. More controllable grip. Lasting speed no matter the terrain. Smooth anti-slick slide and a longer lasting size and shape.

Wheel Shape

Classic Shape - The original Spitfire wheel designed and shaped by the pros who ride them.


99a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.

Spitfire Formula Four OG Classic Skateboard Wheels - white/green (99d)
Ordered the 55. Thought they would be too big. (Usually skate 53/54 conicals.) the 55 OG’s looked huge. Returned and got 52’s now these look small. Haven’t used them yet. Probably let my son ride them, he does skate 52mm wheels. Also wish they came in a 101 option. But I like F4 wheels in both durometer.
