Wanted: Spare for trailer

[DutchVDub]

I'm looking for a 225/75 R15 tire to use as a spare on my trailer. My current spare is too small as its a left over car tire from the tires that came with the trailer. I've since replaced all 4 tires on the trailer with the proper tires that Big-O recommended for my 6-lug axles. As its a spare I'm not too concerned if its a trailer specific tire or not, but would definitely prefer one. I'd also rather not spend the 100$ on a brand new one.
