Tire Bubble problems of the 2007 Honda Accord

I owen a 2007 Honda Accord model lx 4 dr. 6 cyl. The car is equipped with michelin pilot mxm4 p215/50r17 93v xl rrbl tires. At 4000 miles the left front tire developed a bubble on the side. I replaced at my cost. At 8000 miles the right front tire developed a bubble. I replaced it my cost. The tire dealer said it was the car design and the car dealer said it was the tire. I am reporting this because I have been driving for 50 years and owen numerous cars and never had this problem. Please advise . Thank you.
