Welcome to the site, er, I suppose. Everyone OK? Car take any damage?
Lucky you...what caused it? Bent rim? Loose lugs? Stripped bolt?
I've had two come off cars myself...considering the crap cars I drive, it's just par for the course. One was a bent rim ('87 Nissan 200sx), the other was due to my inexperience with torquing lug bolts ('84 VW Golf).
I'm not sure the ***** works on this site, and your post count is too low. I keep my pics & vids on an image server (Photobucket) and use links to put them in my posts.
