Tire Blowout problems of the 2003 Acura TL

Bought new michelin tires in Feb 2008 from costco stores, hackscross road, memphis tire: size 205/60r16 92v made in 2007. In use for 2,500 miles. Rear right tire blew from the side wall while driving in interstate. The entire side wall came out as a donut. No accident occurred. No injury. Concerned about the tire quality of michelin tires. Please advice. Contact mr. Perryadolpus automotive manager at costco phone 901 214 0071; who inspected the defective tire and mentioned that it is a manufacturing defect. A new tire was installed. Greatly concerned about the durability of the other new michelin tires installed at the same time in my 2003 Acura Tl vehicle. Mileage 67,000.

The carelessness of the workers completing construction on interstate 275. I have had to replace two high performance tires; due to a screw which caused my tire to blow with the first tire on the interstate at 4:45 am, had to spend $266. 46 to replace tire. Then a week and a half later while driving on the same interstate going to work had to replace another tire due to a nail, another $200. 00. I think it is the responsibility of dot to make sure all screws and nails are cleared off the interstate since people are having to travel in order to get to work each day. To have to pay over $400, in a week and half; money that I don't have it is taking a toll on me financially. I think dot needs to step up and take responsibility for all the loose nails and screws being left on the interstate.
