I think I saw somewhere that a set of rims and tires sold for about $500. If you have the Goodyear tires I think they are worth squat--I'd give them away. Also you need to consider how good a friend the buyer is------
I had a chance on a set of slightly used(300km) 2012 Sport rims and stock tires(yes, the stock tires are crap) but the price seemed right, about $1500. So, I researched it and I could get the same tires (installed and balanced) on my 2010 Sport for about $1100. The stock clads(new) from a Mopar site were over $300 per rim. Having said that, I don't feel that a used set (even if there are only a few hundred km's on them) are worth near that much, as you can get a decent set of aftermarket rims for that kind of $$$. Not to mention that the aftermarket rims aren't "chrome clad" and are usually better quality. Also, for $1100, you can get a much better tire than stock for that much(or slightly more).
As for my deal, I'm still considering buying them 'cause it is a pretty good deal, but then I'm stuck running those crap tires again. And considering my rims are already starting to show wear, I'm not sure if it's really want a spare set. I'd rather spend a bit more and get a better set.
