MY car came with a hubcap removal tool so HA!
Instead of an "X" shaped lug wrench, I have something similar to this:

but with a flathead screwdriver-style end on the long side. It's curved just slightly, almost like a crow-bar.
I do have a question though... for those of you holding the pizza pan onto the center cover of your wheel, how do you get it off? Do you have to unscrew the pizza pan and completely remove the hardware?
I have a spare set of center caps for my new alloy wheels, but they are held on pretty tight to the wheel, so I know that if I bolted a pizza pan to them, I wouldn't be able to just pry the pizzapan off like a hubcap with the center cap attached.
