Correcting one of the above posts, the Michelin Pilot Sport A/S 3 is not a "3 season tire".

The A/S 3 is an all-season tire, with a compound designed to work in lower temperatures and a tread patter that meets the "M+S" criteria, hence the "A/S" for all-season. The 3 in the name is not indicative of "3 seasons", but instead is meant to express that this is the 3rd generation of the most recent Michelin UHP A/S all season tires following the Sport A/S and Sport A/S Plus.

That being said, they have only mediocre snow traction. This is not a tire for year round use for those in the far north and in Canada. For the majority of the US, it works fine for an all season tire and in a lighter snow area like Maryland, they might get the job done.
