20 x 15 wheel options?

[.030over]

I really want to try to do Micky Thompson 29x18x20 sportsman radials on my truck but I am not coming up with many options on a 20x15 or 20x16 wheel. Anyone know of any options or a good wheel outlet that may be able to help me out? I am looking for something on the lines of a torque thrust II look. I have found some in the $2500 each range but I just don't think that I can bring myself to pay more than $1000 a piece for back wheels. It looks like short of the Micky's, I am stuck with using a 305/50/20 on a 9.5" wheel. I hate to have all of this room and only use a 305 tire
