2006 AX Oops This is what happens when you change to your street tires in a down pour and forget to check the lug bolts. I was lucky that I heard and felt the front tire wobble and was able to pull off in a parking lot when the tire came off. Just 10 more minutes and I would have been on the expressway (IMG:style_emoticons/default/blink.gif)

The fact that all 4 came off at the same time seems a bit suspicious...

Not at all. If i remember from the last time we went through this video a few years back, the video stated that the lug nuts had the wrong size/pitch.

No surprise they all popped off like that. Once the first wheel was gone, the increased load made the others pop off as well.

Completely plausible and there's nothing in that video that suggests this was staged ...

I wasn't thinking that it was staged - who would stage something that was going to wreck their car and potentially kill them. I was thinking sabotage, perhaps. And I am not really a conspiracy kind of guy.

If the lugs were the wrong size and pitch, would it not have cross threaded the studs? Wouldn't that be pretty obvious when twisting them on with your fingers? If they were that loose, they would just keep spinning when torqueing them down, either manually or with an impact.

It was probably some German trying to make Jap cars look bad (IMG:style_emoticons/default/idea.gif)

I saw something similar at an Auto X event in Columbus, Ohio in about 2000. A Sunbeam Tiger lost its right front wheel. It was a pristine car and appeared to really screw up the suspension. The tire went flying off towards the crowd however a large fence stopped it.

I have actually seen this happen twice.

Once was years ago... it was a formula SAE car that used to run with our local SCCA region. It was not a lug nut failure, it was an engineering failure. the axle broke at speed and the wheel took off across the course. I chased it down and kicked it to slow it down and change it's trajectory so it wouldn't hit a kid in a stroller.

At the last AX of the season here, we had an MR2 Spyder lose the right rear wheel. The owner added wheel spacers and race tires AFTER tech, and he was using the stock aluminum lug nuts. They did not have enough thread engagement with the spacers. The amount of G forces he was pulling was too much for the "two turns of threads" he said he had. Turns out that it was, in reality, two 1/4 turns of threads. Ruined the fender, the taillights, the rear bumper cover and a bunch of expensive body parts.


It can happen, especially if you are stupid....

Clearly they were not torqued even it they were the wrong thread / pitch.

There is a guy who shows up at our local autocrosses who always changes wheels after tech. They haven't really fixed their process for this. You would need to chalk their wheels after checking torque, then somebody in the future would have to notice the difference. Never going to work unless somebody gets killed and it's in people's minds.

This was not staged. I remember the incident. I wasn't there, but I did read about it later. The race wheels had thicker hubs than the street wheels, and the lug nuts were torqued with barely a single thread of engagement. Once the car had it's first lateral load, the nuts unzipped.

Summer, 1969, Austin, TX....My left front tire comes off my '56 Chevy, straight into oncoming traffic, hits a Mustang right in the kisser, bounces 20+ ft in the air and ends up in a field covered in stickers. And me barefoot. (IMG:style_emoticons/default/bootyshake.gif) In all honesty, I think mine was a weed failure. (IMG:style_emoticons/default/smoke.gif)

EDIT: BTW, the Mustang didn't get a dent. Go figure!
