Where were you about a month ago??? I just sold a set of stock 17" rims/tires off of my 2009 jk (with tpms and fair amount of remaining tread) for $300! I am also in central NJ and would have loved to hook you up with a deal.
None the less, my advice would be to be patient and scour the forum want ads -- there are some people askling $1000+ for such wheels/tires, and others paractically giving them away ($200-$300) .. dont bite on the high prices -- there is not a lot of demand for these wheels, and they can be found cheap! Good luck -- if I come across any for sale I'll shoot you a pm
