First thing i gotta say is that im new to it.
Never ever before had an experience of picking up right Rim size, to get to the desired look.
Though my car is still on its way, im about to pick it up in about a week or something , so im choosing the wheels for it alrdy )
So lets get down to business )
My aim is to achive something what may look like this

i love the way it protrudes from the arches.
It says ,those rims are
9.0 x 20" with 245/35/20
and
10.5 x 20" with 285/30/20
So, i was just wondering , whether they fit 328xi the right way or not
and what ET parameters do it need to successfully achieve the look i aimed to.

sorry for lack of my english skills )
Thanks in advance.
