Thinking about selling my Rims/Tires. Need pricing advice

So, I have the stock 17" alloys, which I painted black using the bed liner/bumper paint combo that you would use for our bumpers. It's pretty hardy unless you put a socket on the lugs, they scratch a bit. But because of the bed liner paint, its very easy to touch up. 

The tires on them are 285/70/17 MT's. The front two have about 20% the rear about 40% and the spare is brand new.

What should I ask for the whole set? I am using the money to put down on the replacements, which are $3400. Ouch.

Thanks guys.
