Just got our first snow the other day here in Colorado and had a pretty slippy experience on the stock Hankooks, so picked up some iCept Evo W320's
from Discounttiredirect.com for about $780 and had Sears put them on for $60. I did notice today, Discount Tire's site is not listing them for sale so I might have bought the last set!
Will update after first major snow storm, but so far, these are pretty quiet and can't tell much of a difference from the Optimo H426's so far. Did call Tire Rack to confirm that putting 245/45/19's on the rear 9" wheels would not be a problem and they told me it would actually benefit a little bit by having narrower tires on those wheels during the snow, and while the front's look great and are the right size for the 8" rims on the V8. You can see a tiny bit of bowing in the tire on the rears:
