Are you just wanting different wheels, for graphic purposes. Or for different capabilities. Actually you can't do for different capabilities i think. My bad. What you can do is have wheels set to zero opacity. Then put a sequence of of png wheels, animation (so they look as there spinning) over the top, and connect them to car as well. I think that could work.
Thanks for your reply. What am trying to do is, connect wheels for different cars. Seems like only on the gameplay one can add the wheels only. I am creating a game more like hill climb racing.
