Tire Tread/belt problems of the 1997 Honda Accord

Tire blew out on highway and ripped apart at tread. Tires are not even a year old. Tires were bought at pep boys and they refuse to replace tire. I did lose control of my car but luckily I was not driving fast.

While driving at any speed vehicle rode roughly and pulled to the right. Had taken vehicle to dealership, and was informed that tires were causing the problem. Mechanic noticed that all 4 tires separated, bulged, and broke radial belts. On the left front, the radial belt was pushing through and could be seen. Had the tires replaced. Tire size 185/65r15, and dot # hhnxdxcx2600; dot hhnxdxcx3000; dot hhnxdxcx4400. This problem was also reported to michelin.
