Depends on who wants them. I just found a set of Chrome progressive wheels with 295/50/15 BFG T/As rears and 2 235/60/14 BFG T/As, in our paper's Bargain Box. Got all 4 wheels and tires for $200. Off this guys show car, tread almost new, but fits a CHEBY (4-3/4 bolt pattern). Bought them for the tires, wheels are now for sale.
2 years ago I sold my 4 Centerline Auto/Drags with old BFGs off of the Challenger for $450 to a guy that really wanted them.
If you find the right guy, you'll get the right price.
