Technically it does fit, but there was only about 1/8" clearance (maybe less) to the face of th caliper, and it was pretty tight in the back up top by the suspension. I opted NOT to use those, too close for comfort. (Yes, a spacer would probably take care of all of that, but I did think of that when i was there, so I didn't think to ask).

They grabed a 18x8 with +35 offset Aluminum wheel (Koni I believe) that fit real nice, LOTS of clearance for everything... so there is one answer: 18" are no problem on the SS. They mounted up a Cooper tire (not sure what model number) size 235/60/18. I believe that was the most popular size snow tire on the 5th gens... unfortunately it is too tall: it rubs the strut. He offered to do a little more research for me, so i could take off and he'd call when he had more info. He called back a little later and thought the best bet would be those same rims with a Bridgestone (Blizzak) 225/55/18. I started thinking about how that would look, and asked if we could stager the tires and maybe go with something a little wider in the back. He figured he could do a 245/50/18 in the back. Although, after I asked, I'd think I'd rather be able to rotate my winter wheels and get as many miles/years out of them as possible.

He said if I wasn't in a rush to wait a week or two and see if anyone came out with different/better numbers. So, I'm doing exactly that... driving real slow to work in the morning when it's cold out, and waiting to see if anyone comes up with something different. Unless it snows... then I'll stay home and "call in slick".

Thank you!!!
