Hummer wheel ad on Craigslist featuring a crack smoker

Clist This unusual ad for a set of Hummer tires was spotted on the Phoenix Craigslist. I wonder if the photo on the bottom right implies that the seller would be willing to trade the tires for a rock. Click image for a better look. (Thanks, Jess Hemerly!)

Sotp UPDATE: And the ad is back up with a new photo in the bottom right and the additional comment, "I changed my last pic maybe this one won't get flagged"
