Take it back to the dealer and see if they can remove it on warranty. That writing should not be on a new car that has left the lot and they probably have the correct stuff to remove it. Plus, if the wheel is damaged in process, it will be the dealer to blame, not you (translation: any further damage will hopefully be covered by the dealer or Ford).
