I've found better price and selection at Discount Tire. However, I realize they may not be very common up there in the Last Frontier, so it may be worth paying a few more bucks to get something that can be replaced or warranteed at any Wal Mart (and I'm assuming a Sam's Club tire can be warranteed at Wal Mart since they're both part of the same company.)
Back when I had my Subaru and my Ford Ranger, I passed on Discount in favor of Wal Mart for that very reason: I lived in Wyoming at that time and Discount Tire had zero stores in the entire state. That may have changed by now (this would have been 2001-2003) but at the time it was a concern of mine.
