Check those lug nuts, see video Options

This is why there are tech inspections. Maybe he was too busy puttin' on those race shoes.....

From another discussion about this, it's possible that the guy was given 1/2" lugs by the tire shop, and not 12 mm. It's a subtle difference, but 12 mm is slightly smaller than 1/2" and there was probably only a couple thousandths of an inch of actual thread that was engaging the stud. Just enough to resist the torque of the wrench, but not enough to survive the lateral loading of race tires on pavement. So the threads just stripped out of the lugs and off they came...

Oh, I don't think the studs sheared, I think they're just short... which would explain why the wheels came off so easilly. Longer studs and at least they might have stayed with the car after shaking violently...

Of course, I could be wrong...

I actually thought of this later as well as a possibility, and that somehow the thread pitch is similar enough too to get them on. Just seems like you would have to be a real dipshit to not notice that. I put every lug nut on my car by hand and run them down on the threads by hand in an attempt to notice if a thread had become "boogered" or damaged and make sure they "feel" right. It is really bad practice to run lugs down with an airgun or wrench of any sort. IMO.

If you watch the vid again you will see the first hub they focus on is the left rear and those studs are sheared off (you don't see protruding studs and you don't see holes, meaning the sheared off stud is left behind plugging them). It looks like I see one hole implying that stud came out or was missing to begin with. The other hubs appear to have complete studs.

It is just crazy that all four came off at one time - the statistical odds of that must be pretty impressive. I need to play poker with this guy for money as with his luck I clearly cannot lose! (IMG:style_emoticons/default/laugh.gif)
