Michelin Artic Alpin, 225/55R16, mounted on steel rims, set of 4, used one winter. They start with 11/32 tread, and I measured (using a combo square - not the best but what I could find this morning) between 9/32 and 10/32 left. They cost around $700 new, so lets say $350. I live in Hasting, MN. If you want them shipped, it'll be at cost from the UPS store.
