If the tyres are decent about $150 - $200 if you can find someone who wants them wheels.. That wont be easy.
they're ok on the right car but as above $150 I've seen plenty of them with the chrome flaking off them so if i've gotten the impression they're cheapy rims, I guess others would probably think the same too.
How much tread on the wheels? If its a fair bit, 100 bucks. If theyre good for skids and thats about it...50.
