X7 Wheel fitment question.

marblesyrup · 09-10-2024, 08:59 PM

Hello all.

I'm picking up a new to me 2021 x7 M50 this weekend and it comes with the standard 21" wheels which appear to have a 36 offset.

I have some BBS FI-Rs from my last Bentley that I want to put on. It seems like the 5x112 bolt pattern is the same but the offset for my wheels is 41. If I put on a 15mm spacer that should push the wheel out 10mm more than the existing wheels, but I may have that completely wrong because I don't do this very often! Does that sound correct? Will that cause an issue? My existing wheels are 9.5" wide which I think is the same as the OEM.

Also, any suggestions for spacers or spacer sizes would be much appreciated. Thanks!

You can compare the wheel setups at tiresize.com. 41 versus 36 is only a 5mm difference (less than 1/4"). Why are you considering spacers?

Got the car today so will install wheels next week and see. I normally put spacers on factory setups because i prefer a more square look than generally comes from factory; but I suppose 5mm won't make much of a difference.
