I AM NOT SURE WHAT HAPPENED. I WAS DRIVING ALONG ON A RELATIVELY STRAIGHT STRETCH OF ROAD AND THE NEXT THING I KNEW I WAS HAVING AN AIR-BAG FOR BRUNCH. THE INVESTIGATING OFFICER AND THE INSURANCE ADJUSTER BOTH SAID THAT THE LEFT FRONT TIRE LOOKED SUSPICIOUS. IT APPEARED TO HAVE BLOWN OUT THE SIDEWALL AND TREAD AREA.DUE TO THE RESTRAINTS AND VEHICLE DESIGN I WAS FORTUNATE TO NOT BE SERIOUSLY INJURED HOWEVER I DID TOTAL A FAIRLY NEW VEHICLE WHEN I HIT A CONCRETE CULVERT ABUTMENT.( DOT NUMBER: NOT AVAIL. TIRE SIZE: LT24575R16 )
