2004 BMW 325XI Tires Problems

I RECENTLY REPLACED ALL FOUR TIRES ON MY PASSENGER CAR (2004 BMW 325XI). AFTER DOING RESEARCH ON WHICH TO BUY, WE BELIEVED THE RATING IN CONSUMER'S REPORTS AND PURCHASED 4 CONTINENTAL PRO CONTACT TIRES (ORDER WAS PLACED ON 3/3/2009 AND THE TIRES WERE INSTALLED AT TIRE RACK ON 3/6/2009). I HAD A SERVICE CALL ON THIS CAR IN FEBRUARY (2/10/2009) AND THE RECORDED MILES FROM THE VOB SERVICE DEPARTMENT WERE 29,750. ON THE DAY OF THE INCIDENT (4/18/2009), THE MILES ON THIS CAR WERE 30,906. THEREFORE, THE NEW TIRES HAD FAR LESS THAN 1000 MILES ON THEM. AT ABOUT 8:15 PM ON 4-18-2009, WE HAD A TIRE BLOWOUT (RIGHT REAR TIRE) GOING CLOSE TO 70 MPH ON I-95 IN MARYLAND. THE STEEL SIDEWALL COMPLETELY SEPARATED ON THIS TIRE. MY HUSBAND WAS DRIVING AND STRUGGLED TO GET THE CAR OVER TO THE SHOULDER OF THE ROAD. ALTHOUGH IT WAS VERY DANGEROUS...
