2002 LEXUS IS Tires Problems

I HAVE HAD THREE SETS OF COOPER ZEON 2XS 215/45ZR17. THERE HAVE BEEN PROBLEMS WITH ALL THREE SETS. I WAS TRAVELING LONG DISTANCE WHEN MY REAR DRIVERS SIDE TIRE CAME APART AND ROLLED AWAY WHILE I WAS ON THE ON RAMP FOR I24 WHICH IS A VERY BUSY MAJOR HIGHWAY. I WAS PROBABLY GOING ABOUT 35 MPH AT THE TIME THIS OCCURRED. THERE WAS APPROXIMATELY $1250 WORTH OF DAMAGE TO MY CAR NOT INCLUDING REPLACING MY TIRE WHICH I WILL NEVER BUY THESE TYPE OF TIRES EVER AGAIN. ALSO, THIS DELAYED MY TRIP TO VISIT MY GRANDMOTHER WHO WAS DYING IN THE HOSPITAL AT THE TIME. I CONTACTED THE LOCAL TIRE COMPANY WHERE I HAD PURCHASED THIS MOST RECENT SET OF COOPER ZEON 2XS TIRES AND WAS TOLD THEY COULD NOT HELP ME DUE TO THE FACT THERE WAS DAMAGE TO MY VEHICLE. THEY REFERRED ME TO COOPER TIRES 800...
