Every now and then there is a topic started asking about driving on old tires or someone wanting to know what pressures to run without having any idea of their axle weights.  
No idea of the age of this 18 wheelers tires but just to show how an obviously inexperienced driver can lose control in a front tire blowout.  Tragic results for the other drivers.

And as an aside we just drove 1300 miles in the Lexus and I can't understand why anyone would slowly pass an 18 wheeler on a 4-lane.  Get around them as quickly as you can so you don't suffer the same fate as above.
Here's one of the trucks that were hit in the opposite lane, one guy died, 15 calves in the trailer died, other guy miraculously survived.
