20x10 +40 F10 550i

Hey Guys I'm looking at a set of 20x10 (all 4) wheels from an M3CS for my F10 550i. They are 20x10 +40 offset with 245/35 F and 275/30R. Will these fit properly on the 550i or will I need to make any modifications? Spacers in front maybe? Just needed a little guidance before I pull the trigger.

Thanks in advance!

A 10” wheel on the front is going to be an extremely tight fit. I’m using a 20x9.5 ET30 and there’s not much room on the inside. You’ll need a 12-15mm spacer for a 28-25mm ET. You might get away with a 10mm spacer for ET30, but I doubt it.

Are you planning to use staggered tires on square wheels? That’ll look funny in my opinion.
