Assuming no trades plus cash? I have chrome c6 wheels (perfect condition) with BFG Gforces good amount of tread on all of them one is actually brand new maybe has 50 miles cost $389 to replace
Id do $200 on top of my wheels. I think thats fair seeing as you could sell my wheels with the BFG's for about $800 easily ( tires are almost $400 a piece)
