The only reason I can see that you'd want slick wheels for this game, is to use two of them on a long wheelbase 4WD robot, so it is reasonably easy to steer it.

I can think of better solutions, mostly involving the use of more wheels, and aranging them in a clever way.

Traction is a good thing. Turning ability is a good thing. Finding the right compromise might take some experimentation.
