Spitfire Formula Four Conical Full Skateboard Wheels - white (99d)
Wide riding surface lets you keep speed while using slightly smaller wheels. F4 is the best urethane!

I’ve tried it all. This is the best formula for park and street. The shape offers major stability and and a great slide when you need it.

Spitfire Formula Four Conical Full Skateboard Wheels - white (101d)
love the contact patch, wheel size, and they slide great. I prefer these over small contact patches atm. I've tried formula fours in sizes 50, 53, 54mm. None of them feel as stable to me as these conical full ones. Not sure I'll ever go back to smaller contact patch.

Asked by Adam on 5/31/2017
Why did the price for wheels get jacked up $5 all of a sudden?
