Spitfire Formula Four 93 Radial Full Wheels combine Spitfire's 93 duro "Soft Slider" urethane with the wide, rounded Radial Full shape. They roll smoother and quieter over rough pavement, cracks, and crusty street spots than a hard wheel, while still sliding predictably for powerslides and board slides. Available in 54mm, 56mm, and 58mm.
Why Skaters Choose Spitfire F4 93 Radial Fulls
- 93 duro "Soft Sliders": A softer formula that grips and absorbs rough ground but still breaks loose for controlled slides.
- Radial Full shape: Rounded edges with a fuller, wider riding surface for stability, grip, and smooth carving in bowls and transition.
- Formula Four urethane: Spitfire's premium formula, built for long-lasting performance, abrasion resistance, and flat spot resistance.
- Three sizes: 54mm for all-around street and park, 56mm for a mix of park and cruising, and 58mm for bowls, transition, and rough roads.

Which Size Should I Choose?

Frequently Asked Questions
Are Spitfire 93 duro wheels good for rough streets?
Yes. 93A is softer than the 99A and 101A wheels most skaters use at the park, so it absorbs cracks and rough pavement for a smoother, quieter ride while still allowing slides.
What is the Spitfire Radial Full shape?
The Radial Full has rounded edges and a fuller, wider riding surface than Spitfire's Classic shape. It offers more grip and stability, which makes it a favorite for bowls, transition, and carving.
Will 93A wheels still slide?
Yes. Spitfire calls their 93 duro wheels "Soft Sliders" because they're tuned to slide controllably despite being softer than standard street wheels.
Do I need risers for 58mm wheels?
Often, yes. Depending on your trucks and deck, 58mm wheels may need risers or high trucks to prevent wheel bite.
How many wheels come in a set?
Each purchase includes a set of 4 wheels. Bearings are sold separately.
