The cost of wheels and tires.

Buy new, and get the new wheel price $.
That's why I find used wheels, for penny's on the dollar.
Nothing a little paint or powder coat won't fix.
And in regards to BFG's ? Not the best performance tire out there, but they work fine for most. For the muscle car look, they are hard to beat.
I believe Coker bought the rights to them. So now you know who to blame for the BFG pricing.
