Remember that if you are using gears, it have to be from Small Parts this year. Not sure if they have big enough gears compare to what you want. But if so, they are probably going to save you a lot of machining.

As for making your own wheels out of metal, I would advice you to design the wheels so that they especially do not hurt the carpet in any way. Make sure no matter what happens, they do not damage the field. Think about the wheels doing different motion: spinning, twisting, sliding, or pushing against the ground because of heavy weight of the robot. Earlier discussion suggest using timing belt on the wheel. So you might want to explore the option to machine wheels that can fit two-sided timing belt on them, and gain more traction that way.

Another way I've seen many teams do is to cut slots out of the surface of wheelchair wheels. You probably want to do this on your wheelchair wheels anyways to get more traction from them...
