Thanks for the replies.
I used the calculator to check a particular wheel that is 20 x 10" ET 34. BMW OEM 20" wheels for F10 would have 20 x 9", ET 44. I know from some members of this forum that they have installed this particular wheel to their F10. They find the wheels fit fine and don't rub anything. However, I wonder, although they don't rub anything, would the different offset, thus different lateral wheel position compared to 'stock', significantly affect suspension/handling or any other things (that might be harmful yet not noticeable)?
