Sort of. We added added a high-traction material to the edge of the wheel. Because there's practically no weight on the rear wheels and that the Skyway wheels have a very low coefficient of friction, we had some huge traction issues. While it was cool to have the robot do donuts and drifts all the time, it made it almost impossible to turn effectively.

To add the tread, we practiced with the robot until there was a flat edge on the top of the wheel (if you are doing this at home, I would do this with a lathe). We then drilled an 1/8 inch pilot hole through the tread and the wheel, then fastened it with a drywall screw into the wheel's rim. If you want to do this, insert screws on alternate sides of the wheel at about 30 degrees apart.
