Spitfire Formula Four Lock-Ins Full 54mm/99a Skateboard Wheels

These wheels maintain the same asymmetrical shape and design you know and love, featuring a conical cut profile opposite a straight edge side, but now offered in a wider shape. Overall, the idea behind this asymmetrical shape is to provide you extra scope to lock your wheels and trucks into grinds better. In addition, these wheels consist of Spitfire’s signature Formula 4 urethane which retains more material, cone less and keep their original shapes and sizes longer than any other wheel!
