cking,
I have them on my car. Only about 3,000 miles so far, so I can't say anything about treadwear. I think the reviews on tirerack are accurate as far as my experience has been. Good dry traction, excellent in wet. Haven't had snow yet, so I can't say personally. But I tend to wait for the plow anyway before I venture out.
I also agree with the various reviewers re. softer sidewalls and possibly not the best for taking turns.
I bought these when they were priced at $145, they're now $117 I think for the 9-5 Aero 225/45-17 size.
If you're going to get dedicated snow shoes anyway, and you can afford the Michelin Pilot Sport A/S Plus those would be a better choice for dry and cornering stability.
There's more stuff that needs to get fixed in my car, so right now I'm happy I kept my expense on tires low.
