If you want maximum winter grip for your performance car -- without sacrificing actual performance -- experts and owners say the Michelin Pilot Alpin PA4 is the best winter tire you can buy; the downside is that it's pricey. Runners up, such as the Nokian WR G3 (Est. $120 and up) or Dunlop SP Winter Sport 4D (Est. $95 and up), sacrifice some performance, but still handle ably in all but the worst conditions. They also cost less and come in smaller sizes than the Michelin.
Sporty, even on ice and snow. If you drive your sports car or performance sedan on cold, snowy, or icy roads, the Michelin Pilot Alpin PA4 is for you. Its rubber stays soft in cold weather, so you won't slip and slide -- and yet it still handles crisply according to expert tests and user feedback. "They really do feel like summers," raves one owner at BMW-centric M3Post.com, although braking on cleared roads is "just so-so" in one top test (like other performance winter tires).
The PA4 impresses on snow and ice, too, beating its rivals in two expert tests. "Fantastic tire ... makes you think that your car has four-wheel drive in the snow," writes a BMW owner at TireRack.com. Still, you won't enjoy the ultimate snow-and-ice grip of the harsh-winter Michelin X-Ice Xi3 (Est. $95 and up).
Very comfortable -- and pretty quiet, too. Traditionally, performance winter tires ride softer than summer tires -- and that holds true for the Michelin Pilot Alpin PA4. It rates "very good" for comfort in a top test. "Right away I noticed that those expansion joints and holes in the road are not as sharp" as with summer tires, writes one satisfied owner at M3Post.com. One owner at TireRack.com initially complained of vibrations at highway speeds but said those smoothed out nicely after a two-week break-in period. It's quiet for a performance winter tire, too. One top source rates the Michelin PA4 "good" for noise, while most of its rackety rivals rate "fair" or "poor."
Expect long tread life. Unlike most winter tires, the Michelin Pilot Alpin PA4 carries a 30,000-mile treadwear warranty. So did its predecessor (and our previous Best Reviewed), the Michelin Pilot Alpin PA3, and the PA3 tire delivered excellent tread life, owners at TireRack.com report. There's a catch, though. You can't collect on the PA4's warranty until the tread is worn dangerously thin, at 2/32 inch (TireRack.com recommends replacing winter tires when they have 5/32 inch of tread left). And you must have installation documents to prove that you run the tires only between September 1 and April 30.

The Michelin Pilot Alpin PA4 impresses Phillips (About.com's guide to tires and wheels) at a Michelin press event. It handles every snowy, icy road condition on the Quebec test course, including a sweeping uphill turn that stumps other tires.
