Spitfire F4 Radial Full 99DU 56mm Skateboard Wheels

Spitfire F4 Radial Full 99DU 56mm Skateboard Wheels

Spitfire Formula Four Radial Full combines durable urethane with a wide wheel profile and a 99DU hardness rating. The result is a skateboard wheel offering a balance of grip, control and slide performance for skaters who prefer a firmer feel underfoot.

Formula Four Urethane and 99DU Hardness

Spitfire's Formula Four urethane is designed for durability, smooth rolling performance and resistance to flatspots.

99DU provides a firmer and more direct feel than 97DU, with less cushioning and a more pronounced release during slides. This hardness works particularly well on smooth concrete surfaces and ramps.

Radial Full – Wide Contact Patch with a Rounded Profile

The Radial Full shape features a wide contact patch and rounded edges. The wider riding surface provides stability and grip, while the rounded profile contributes to a smooth and responsive feel during turns and slides.

This shape is well suited to skaters who prefer a wider wheel profile and a more stable feel on landings.

For Park, Bowls and Transition

With a 56mm diameter, these wheels are particularly well suited for skateparks, bowls and transition skating, where the larger diameter helps maintain speed. The combination of the Radial Full shape and 99DU hardness provides a stable contact patch with a firm and responsive feel on smooth concrete surfaces and ramps.
