I spent weeks debating on running a 2nd set of wheels and tires for the upcoming winter on my new 2013 WRX hatch or going with a replacement set of all-season tires. I know the consensus around here is to run two sets so you're not compromising on performance or safety in either season. But after reading the glowing reviews of Michelin's new Pilot Sport A/S 3 UHP all-season tires, along with the very competitive pricing on TireRack, I sprung on them. I've only had them on my car for 350 miles or so, but I already love these things. They're considerably quieter and smoother than the stock Dunlops, and there's no loss in performance, cornering ability or grip whatsoever. They just plain stick to the road. Check out the review and test results from the website below from earlier this year. These actually outperformed other brand's summer-only tires, and I can't disagree with any of their opinions. I have no idea how these will perform in the snow since they're so new, but here in Cincinnati we get very little snowfall each year, and if I've been able to make it all these years on cheap all-season tires on my previous FWD cars, I should have no problem with these on an AWD car. I just wanted to throw this out there to others who are on the fence about tire choices.
