I really have no idea what happened. I was driving home tonight, and about 2 miles from my house it sounded like I ran over any empty 20 oz bottle. I stopped and checked the rim and fenderwell (I didnt see anything in the road at all). I didn't notice any damage the time, so I got back in and started to drive home. I stopped at a gas stating just so I could check in better light, and thats when I noticed the hole.
It does look like something punctured the tire, but the hole in the rim is about 4 inches away from the hole in the tire. The rim is still completly round, there is no flat spot where the rim is broken, but the rim does bulge outward(in tward the hub) about a 1/4" around the hole in it.
