Hello
I post here in english because I don't speak German :( Is a gentleman can translate this post, I'll thanks him :)
I currently have 4 Alpina 18" wheels on my E46 Compact, the classic wheels. Thoses wheels can be bought from Alpina in 8x18 (225/40/18) front and rear or in 8x18 (225/40/18) front and 9x18 (255/35/18) rear.
My "problem" is that I use 4 9x18 wheels with 255/35/18 even for front wheels. It was not a problem... until the technical control reject me :)
Here is the point. If you have a set a 4 8x18 Alpina Classic wheels on your car, I'm ok to trade 2 8x18 from you in exchange of 2 9x18 from me, for free (in same tire condition).
See you,
Thomas
