Try craigslist too, people who look for stuff on craigslist are looking to get something that day and are prepared to come pick it up. I can't really tell much about your tires but I doubt you're going to be getting more than $150 $200 at max for all 4 and no one is going to want to pay $100 shipping on that, it might end up being even more than $100 I dunno.
Just this weekend I decided I needed some better tires than the crap my used z71 tahoe came with but I didn't have more than $200 to spend so I wanted to get something temporary cheap and used. my local craigslist was filled with full sets of z71 wheels + tires for $100-$150. Yours look better than the z71 style and not generic and boring like z71 style and probably aren't flooding the used wheel market like z71 ones are but factory wheels aren't going to bring much. (I was about to get some highly polished big-dish oem escalade wheels with 20k tires for $275)
Also, no offense but good capitalization, punctuation and grammar go a long way on ebay for getting taken seriously on your auctions.
