Hugh, several years ago, there was a rash of runaway truck tires in Ontario. They figured out that the problem was that mechanics were over-torquing the lug nuts that hold the wheels on — I guess that would lead to the studs snapping and letting the wheel loose.

#24, JC,

And I’m sure many are tired of your explaining the jokes.

Where did the tire leave the skid marks?

Did the tire rub him the wrong way?

#19 Several years ago I dropped my loaded trailer that was going into Mexico and backed under another trailer that had just returned from Mexico. When I did my walk around inspection I noticed something unusual about the studs and lugnuts on one wheel. Turns out only half the studs had been seated to the drum. The tire mechanic had replaced some tires on the trailer but had done a dismal job of mounting the wheel back on the axle. He never noticed that half the studs spun loosely under the air wrench.

If I hadn’t caught that, 100 miles down the road both wheels of that dual would have come off. And when they do, they roll for a long way or until they hit something.

Well lets see, being a police officer, you never turn your back to the vehicle you are behind, be it a traffic stop, assisting a motorist or what ever. We are trained to position are patrol vehicles so it protects us from vehicles. You just cant train/protect against something like this. Some of you get it and some of you are just idiots.
