not sure on all this but this is my estimate give or take a hundred but i will go with $600 or so. cuz the 17" rims new are like $150 a piece i think and then the tires are prob. $100 a piece. and since they are used u would have to depreciate them. Why you gettin rid of them anyhow?
I'm going to put the AFS Cobra R 10.5" ones on the rear. I'm debating whether to buy just the rears or to get a whole new set. I think it might be easier to sell mine as a set of four and just buy all new ones.
Remember new ones have drop a LOT in price. If yours arent way lower, nobody will buy them. Most people are going to fork over a little more $$ to have new ones.
