640M on 2011 35i?

Scott_S · 01-14-2020, 09:24 AM

I picked up a set of 640M wheels with winter tires for my F80, but I ended up parking it this winter and driving our E70. Is it possible to run the 640s on the E70 with a square tire setup? They currently have 255/40/18 Continental Winter Contact tires so I know the overall diameter will be smaller and it will throw the speedo off for sure.

You’ll have to check and see if the bore sizes are the same. If not you MIGHT....be able to use a centering ring to make them fill the void in the rim. Google the bore size for both sets of rims and that should let you know what you’ll have to do.
