You don't use straight metal wheels in FIRST. If you use metal wheels, make sure you put belting around the edge as a traction device. There is a rule in Section 4 about no damaging the playing field with a traction device (and no metal on carpet). Also, I think most FIRST teams use wheelchair wheels.
