Value of used Cooper STTs?

[Cazador]

I've got a set of 37 x12.5x17 Cooper STTs that are just about 50% tread left. I'm throwing new ones on next week(I always replace tires at the 50% mark) and am going to sell these. I don't want to deal with shipping, so I was thinking of just throwing them on Craigslist or Ebay with local pick up. Any ideas what these would be worth? $25 a tire? $30? 40? More?

I have ZERO idea if they have any value...but if I can't get at least $100 out of them, I'll just throw 'em on an older set of H2 wheels I have as back-ups.

Also, what are OEM wheels(pre-2008 style) and tires bringing these days??? I have two sets of them with tires on, both from 2006 trucks, both non-chrome. One set has OEM BFGs with 27,000 miles on them, the other has BFGs with 35,000 miles on them.

Thanks for the help guys!
