Description
The Spitfire Formula Four (F4) Classic 99A Wheels are the gold standard for all-around skateboard wheels, combining the most popular shape in the world with Spitfire’s elite performance urethane. The Classic shape features a medium-width riding surface and rounded sidewalls, offering a timeless feel that is proven for speed, control, and technical precision.
The 99A durometer is widely considered the most versatile hardness, providing enough grip to handle slick skatepark concrete while maintaining a smooth, predictable slide on rougher street spots. Because they are poured with Formula Four urethane, these wheels are exceptionally resistant to flatspots and hold their size and shape significantly longer than traditional wheels.
