I'm looking for winter wheels/snow tires for my 08 Odyssey EX-L, which takes 5x120 ET40 wheels.

Locally there is a set of BMW wheels from a 97 740iL, which are 5x120 ET20, I believe. They come with 215/65/16 snows.

Do you think this might work? Will the additional 20 mm offset be prohibitive? Even with the skinnier tires? Thanks. I'm only considering this since the wheels are a good deal and Odyssey rims are hard to come by without spending large for OEM, or settling for $62 steelies.
