because there is no regulation on when a tire is not to be sold and considered out of date.
there was a show on the telly just about this about a year ago. some vans were crashing from tire failures and they found that tires were just purchased in these cases and that the tires ( after a long drawn out search for the manufacturing date code reading tool) were as old as 15 years.
but sold as brand new.
they looked around tire store and small mom and pop gas stations and found that most tires on the shelves were over ten years old.
so they were trying to get laws to regulate how long a tire can sit on the shelves in warehouses before they are deem no good.
never heard anything more on it.
I'm sure the families who lost loved one in these accidents got paid very well and that sqwashed that.
