The base 18's are the only ones I have not tried. If you already have the wheels you can always just drop in our template and see if they clear:

Make sure it prints 1:1 sometimes computers/printers will adjust it. Then just cut it out and drop it inside the wheel and take a look. I usually recommend gluing it to a piece of cardboard or heavy card stock just to give it a little extra rigidity but it's not necessary.
