I currently have the OEM 17" wheels on my 06 525i Euro Spec.

I found some decent F10 OEM wheels with 18x8 ET30 front and 18x9 ET44 rear, wrapped in 245/45 R18 and 275/40 R18 rubber.

Quick check on willtheyfit shows they will poke 10mm less and 10mm closer to the strut. Also the circumference is 3.62% more and resultant speedometer error.

Can they be fitted on my car and still provide the correct speedo?

Thanks
