Tire Sidewall problems of the 2004 Jeep Grand Cherokee

I purchased at from michigan auto wheel & tires (mawt) at 38190 van dyke Ave, sterling heights, mi 48310 and had them mounted, balanced, and installed on my vehicle in preparation for my vacation trip. While on my trip one of the tires went flat. When I had the tire replaced, I learned that the 4 tires were not new, but were all about 5 year old and each had a patches on the sidewall. When reputable dealers have a tire that ages out of their inventory at approximately 5 years, they destroy the tire by drilling the sidewall. They pay a recycler to dispose of the tire. In my case, the tires had no sign of wear and appeared new. It appears that mawt is involved in purchasing scrap tires and repairing them, or purchasing repaired scrap tires, and selling them as new. This is a dangerous practice. I have a significant amount of additional information and documentation.

Consumer states while traveling 55 mph and without any indication passenger's rear tire sidewall blew out.
