Pulling out of my garage this morning, I noticed my car was making a clunking sound on the passenger side. It disappeared promptly as I exited the garage and pulled out onto the street, and I figured it was simply due to the chilly weather, with it being about 25F outside. About 5 miles down the freeway, I noticed the clunking sound came back, and was quite violent this time, and I started to smell burning rubber. I pulled over to the side of the road, hoping to ease my way to the nearest service station to see what was wrong; however, my car did not make it. I got out and inspected all sides, and that's when I saw that the tread separated from my front passenger side tire, and there were chunks of tire on the road. According to the dealer at the last visit two months ago, there still had been.7 cm left of tread, and what they told me was plenty to drive on for quite some time. To correct the issue, I replaced the tire with a spare, and have an appointment to get new tires tomorrow.

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. 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.
