hubcap
The center cap just snaps on, there is nothing holding it except the tension of its' ring shape. I pry the outside chrome ring off first so as not to dent it while I pry off the center rim. If it will not come ,get more leverage with a bigger bar. It will come off. My only other suggestion would be to look at the rim very closely around the edge of the cap and notice the small ridges that hold against the cap. Pry right next to one of these ridges. Good luck.
