2002 Buick Century

Right front Cooper GS5 Grand Touring 205/70 R15 96T with only 862 miles on it had a complete air loss/went completely flat when car was turning into a parking lot. This is one of a set of brand new tires on the car. The car was never driven on a highway after these were purchased. Only local driving at 45 to 50 MPH max. Tire was taken to a tire shop in hopes of getting it plugged/repaired. They found nothing had penetrated the tire. They could not pressurize the tire. Air was blowing out all around the outside bead and could not be seated. They put lubricant around the bead inside and out and gave it some rapid shots of air on the machine. It started to hold pressure but immediately had a roughly 4 inch section of the sidewall start to balloon out. Technician said he was afraid it was going to blow up in his face. He chalk marked the defective area on the tire and said the bead and sidewall had failed in that ballooning area and the tire was defective and not repairable.
