Depends on the tread, we used the big wedge in previous years. this year, idk. But we lathed the wheels 1/4" and then took screws and drove them in, deep. They dont come out, and the screws dont touch the ground if screwed in correctly. Now sometimes, depending on the wheel, the screw will come out the plastic, just file the end of the screw so it wont hurt anyone when touching, you know like almost everything on your robots. lol.
