I put Nokian WR's on my stock wheels and they're awesome. No need for added weight in the back. Nokian makes the only all-season tire with the severe service rating. With $1000 in rubber, i didn't want to throw them away after 12,000 miles. With the daily commute at 70 miles and my girlfriend in Chicago (I'm in Kalamazoo), I would have made quick work of strict snow tires. Worth every penny.
