205/50 has a 1mm difference in rolling radius to the 225/45 tyre and is perfectly fine on a 7.5 rim according to the tyre spec. I checked this before I bought them because I had the same concern.
You could not put 205 on an 8" wheel.
The rears would fit on my 330i E91 and looked fine, but it's your call. Where in the country are you, as you're welcome to try them if you're local?
I am not worried about the tyre sizes at all, it seems well within specs for the wheels etc, just saying they would have originally been supplied by bmw as a specific winter set for the M3 & not for the regular E46 & they would have been fitted with 225's all round.
I am based just outside Reading BTW, hence the interest as you could get them to me.
