Can't recall where I recently read this trick, but it sounds like it might work:
Pull off the wheelcover and dab a little glob of paint on the rim on each of the scratches where the grippers have slipped and left their mark. Then put the wheelcover back on the wheel while the paint is still wet. When it dries the paint will hold the wheelcover on. Be sure to repaint the scratches every time you remove the cover.
I have not needed to try it, but it seems like an easy little thing to do. And it's just crazy enough that it might get the job done.
