D40 16's on a new D22

Hey folks.
Family friend in Newcastle, has a set of 16' standard D40 rims. I think they are 16x7 255/7 16. Come of a new D40 about a month ago.
basically look like this.

Now i like the look of them better than the stock D22's. And hes willing to give them to me, all i gotta do is pay for postage.
Anyways, he was a tad concerned they would not suit the new D22's. Told me to find out. Something to do with the off-set. And the dealer gave me a rather technical "not possible" as an answer.
Why exactly is this? Is it because the wheel will be sticking out too much to the side or... ? I'm just a tad confused and wanna be sure 100% before i commit to them.
Thanks ahead.

I'm fairly sure it's been spoken about here and the same response was offered. D22 wheels can't just be put on a D40 or vice versa. Do a search for off set in the tyres section I'm sure you'll find something more about it.

yep... wont fit. Different stud pattern diameter.

Ok it wasn't offset that brought it up but d22 rims in a normal search brings it up
