Woof, you were lucky.
Several years ago, my husband was driving our SUV behind a semittrailer when the trailer blew a tire. It hit our car, like you, he was fast enough to swerve so that the pieces didn't come thorugh the windsheild but they did destroy the right front quarter panel. Of course the trucker just kept on truckin.
He called the State Patrol who responded and the trooper said what we've been seeing for several years, more and more blown truck
tires.
When I was stationed in Texas, it was common knowledge that Mexican drivers would rent new
tires to put on their rigs and pass inspection to enter the US, and once they were in the US, they'd return the
tires to the guy who made a living doing that . The trucker would then put his bald maypops back on the trailer/truck. And the Bush administration changed the law constraining them from a 25 limit in the US to being able to drive anywhere in the country. So now you see blown truck/trailer tires all over the place.
Is it related? I don't know, but as I said, tire scraps are common now. And it's why I give the big rigs a lot of room...I stay far behind them. I just wish they do the same. I usually drive in the right lane at 60 mph, the speed limit (for trucks) and they tailgate the living daylight out of me.
