Well, here's an idea but it's liable to ruin your wheels to. Finger nail polish remover with acetone in it will usually debond CA-type glues. Unfortunately it also softens styrene, but it evaporates quickly. I've used it before and if you're lucky it won't hurt things too much. Try it on some scrap first and see if it will work for you.
There are also CA debonders available that are probably more reliable, but I've never tried them.
