Gents,
I have a dilemma, I have some aftermarket wheels, and I always like to keep my car as original as I can. So, currently, I have this setup:

It has 225/45/17 - Good Year Eagle F1 ASYMMETRIC 3
And I am considering to buy 205/55/16 wheels:

How does it fit Z4?
What I want is to have all-season Michelin Crossclimate+ tyres on those original 16 wheels and experiment with summer tyres on 17 wheels and use them on the track (so I can change wheels easily).
I am listening to your advice, thank you!
