- East Greenville, PA, USA

Here's what happened on 7-26-09 I was on my way back to fort worth from austin, tx from a trade show when about 3:00 pm on hwy I-35E 19 miles South of waco tx the I felt a sudden vibration and thumping in the front. I started to slow down to get off the road to check it out when front left tire blew out, causing the truck to severely veer to the left trying my best to keep the truck from rolling, then hitting the concrete guard rail which deflected the truck enough to slide down the barrier for about two hundred feet till it stopped. I felt lucky to be alive. If I would have been in the right lane at the time I would have taken cars out as well. I was able put the spare on and limp back home this is the third tire out of the four all the same batch I have had thrown tread and the last was blow out! all installed at the same time and brand. First one threw tread on 10-14-08 left rear did some damage. Ok things happen, I have warranty on it from discount tires, they replaced it.. then the next threw off it's on 7-21-09 right rear tire. Discount tire replaces it too.. I had them look at the others tires and check for defects, everything was fine.. five days later this blow out on the drivers front' three tires throwing tread in 9 months and two with in a week I was thinking this is not a coincidence, this is the definite sign of defective tires. I still have one more tire on the truck which looks perfectly good.. I will ask to have replaced as well. I'm not having any luck with Michelin.. they gave me a generic excuse and are not willing to do any repairs to my truck this is why I need your help!
