1992 UTILITY TRAILER Tires Problems

I HAVE 2 BLUESTAR TIRES THAT I WAS TOLD ARE NOT PART OF THE RECALL. THE PLACE I BOUGHT THE TIRES FROM IS VERY ADAMANT SAYING THESE TIRES ARE NOT PART OF THE RECALL. I WAS DRIVING DOWN THE ROAD WITH A 2 WHEEL TRAILER WHICH THE TIRES ARE MOUNTED ON. I HEARD A LOUD POP SOUND AND I STOPPED TO FIND OUT WHAT HAPPENED. AT FIRST I COULD NOT FIND ANYTHING WRONG. BUT THEN I NOTICED 2 BULGES ON THE SIDEWALL OF ONE OF THE TIRES. I WAS PULLING IT WITH OUR TRACTOR AND ONLY GOING ABOUT 10 MPH. SOMETIMES I PULL THIS TRAILER WITH OUR PICKUP, WHICH COULD CAUSE AN ACCIDENT, BECAUSE OF THE FASTER TRAVEL SPEEDS. THE TIRE DIDN'T COMPLETELY BLOW OUT, IT JUST POPPED VERY LOUD CAUSING THESE SIDEWALL BLISTERS. I WAS TOLD THESE TIRES ARE NOT PART OF THE RECALL, BUT THEY DEFINITELY SHOULD BE....
