What's needed to make these wheels fit?

I'm looking at these for a winter set but the guy says they won't fit on a 335. They look to be e46 wheels, any clue how big of a spacer would be needed?

I don't know, that's the issue. He said he had one on his 335 and it rubbed the caliper, so I'm assuming it needs a spacer but I don't know how big.

Go on google and search "how to measure offset" then follow the instructions and measure and do the math. It's not very complicated.

15mm spacers should be a safe size.

The way those 205's are on that wheel, it looks like the wheels are probably 17x7.

So even if the offset is +50, with the 15 spacer, it'll bring you down to a normal +35 with plenty of space due to the 205 width and 7in wheel width. If the offset is +40, then it'll bring you down to a +25 offset which would make it look better and closer to flush. And I doubt that wheel has a 30-something offset... most likely a +50 or low 50s if the guy is saying it rubbed his calipers a little.

I just found these wheels too

The guy told me they're a +40 offset and says its a 17x7.5" even though he's listing it as 17x7"

Would a +40 offset work with 335 brakes? This may be a better deal if I don't need to buy spacers all around
