As I don't think I'll be able to find a good winter setup using my OEM wheels, I've started looking at 17" wheels. Thanks Gill for this post, very helpful. I just put together this table with a little bit more information. Can you confirm the info is correct? I wanted to check where the outside face of the wheel would end up in relation to OEM. I don't like wheels that look "sunk in".
Hopefully this is helpful to others as well.
hrmm tried pasting excel table with no luck. attached as image instead.
