Hey, thanks for the answer.
I was also considering buying another set of rims to fit four 225/40 R18 tyres.
I went to BMW yesterday, and they strongly advised me against non BMW-rims, the guy really wanted me to buy their winter kits (bmw rims and bmw 'star' certified tyres).
What do you think about that?
Otherwise, I don't really know what dimension I should look for the news rims.
Right now I have:
FRONT: 7.5Jx18 ET45
REAR: 8Jx18 ET52
A website tells me I should get 8Jx18 ET 43, that should fit without any issue right?

Thanks a lot for the answer, you are really helping me since people in garages are trying to rip me off
