I just bought a set of 4 Winterforce UV's for my Expedition. It was down to a set of the Firestones or Blizzak DM-Z3's, but the Firestone store wanted $35 more per tire for the Blizzak's, and I only need the winter tires for this year and next winter maybe, so I went with the value option. I currently have a set of Winter Dueler DM-Z2's, but they are 8 years old and have only 1/2 the tread remaining so it was time.
With state tax included, the price at the local Firestone store was within $1/tire of the delivered Tire Rack price, so I bought 'em at the store instead. I've run the older Firestone Winterfire snow tire on some of my other cars, and was pleased enough with them, so I think I made a good decision.
