Thanks Clockwork, I have heard that the Nokian Hakka's (such a mouthful) are a pretty awesome tire (if not a little pricey!) I also see that Pirelli do in fact offer studs in the 20" staggered option, in the Winter Carving Edge.

And Joshdub - fair call, yes, I'm not sure those wheels will look good on the 4.6is, any suggestions on a better looking rim? Should I be looking at 19" as well, or will that be just as difficult/expensive tires-wise as the 20"?

And Pnoyako85 - I can't seem to find the Pirelli Scotto?
