And the Wheel Goes 'Round and 'Round

I'm not sure what sort of machining capability you have but the wheels without hubs are available for much less here http://robotcombat.com/marketplace_colsons.html

EDIT: And here are some very similar wheels with hubs for cheap, but the hubs are Delrin.

We have used the 6" ones direct on this motor before in a special project without problems, but it was not a competition robot (did not engage in pushing matches). Also, it should be noted that there were two wheels per motor, one on each side.
