I bought a new full size tire and steel wheel from Discount Tire (www.tires.com). I bought the lowest priced tire that they had. It fits fine in the spare tire well in my '95 850 - I believe there is a plastic or styrofoam spacer that you can take out to accomodate the extra width of a full size tire. If you are only going to use it as a spare you would be okay to select one of their lower priced tires. I notice that you can get a Nitto tire for $43 and a new steel wheel is also $43. They mount and balance it for free, just pay the shipping. Be careful with buying a used tire as you don't know how old it is and what type of abuse it may have been exposed to. You can also check at The Tire Rack but I think they have sold out of steel wheels for this season.
