Anybody know all the specs on the factory alloy wheels? (also called "wide 6")

I know they're 15", but what width? 5.5 or 6? And what weight? I assume they're a bit lighter than steel, but then I've seen stranger things.

And where can I see (or find) the Euro spec factory alloys. Europe usually gets all the good stuff.

Can't help ya, but I'm kinda wishing I would have gotten those rather than the ones I got from discount tire.
