How about getting one of those round patio furniture tables with the expanded metal type top? I've seen them in various colors (black, white, green) and in various diameters (usually 3' and 4'). Cut the top off and bolt it to the tire. You could probably find one used for pretty cheap and paint it some really cool color you like and even paint the car number of you favorite driver on it or something. Red against the black tire might look kinda cool.
