17" fit on the 3.0si - my winter set are 17" square, the recommended winter size by BMW.

For the OP, offset might be an issue but there are plenty on here who understand them better than me! There are a couple of sites you can compare visually online. I would definitely suggest a square set up for winters.

Staggered Wheels vs Straight Wheels

I’ve read and reread the posts above, and think that, in summary, there’s nothing preventing me from running my Zed on 17’s.

I’ve been offered a set of alloys from an F30 3 series. They’re a set of 396’s running 225/45/18 tyres. I can see these tyres listed on the sticker inside the door, so the tyres are good.

The wheels are 8jx18’s with an offset of 34. I’m a little confused with the offset requirement. As my current wheels have a staggered offset (ET29 and ET40), when choosing a straight set would these wheels with an ET34 offset be ok, or would I have problems?

Many thanks again in advance.....
I'm still a newbie in terms of wheel offsets! :roll:

But I did stumble across this, which may be helpful!
