My wife & I have a 1996 Ford Escort wagon that we purchased used in 2008. At the time of purchase it had a set of 4 Bridgestone insignia sl tires that still had reasonable tread depth remaining, so we decided to continue to use the tires until the tread had worn down more and needed replacing. On Friday, July 30, 2010, my wife was driving down the freeway at approximately 70 mph when part of the rear passenger-side tire tread separated from the tire and shot against the sheet metal on the inside of the wheel well. It ripped a large hole in the vehicle's sheet metal, shot many small pieces of tire through the hole into the interior cargo area in the rear of the vehicle, and caused the vehicle to stall at the same time. Thankfully my wife was able to handle the car during this catastrophic event and successfully maneuver it onto the shoulder of the freeway. We had the car towed home since it would no longer start, and when it arrived I noticed the large hole that had been made inside the wheel well by the tread separation. The tire still had pressure, but at that time I saw that about half of the tread was completely missing. Since the Ford Escort has its fuel cutout switch installed against the passenger-side wheel well, I checked to see if that had tripped and it had. Once it was reset the car was able to start and the engine ran normally. As a result of this catastrophic tire failure my wife was placed in an incredibly dangerous situation, stranded on the road, and significant damage was done to our vehicle. It is my understanding as a former automotive engineer that tire failures of this kind are not acceptable and any tire that is susceptible to this failure must not be used. I have replaced all 4 tires with new tires of a different brand and am working on having the car repaired. Approximately 2 weeks prior to this event I had checked the pressure in all 4 tires and had inflated them just under the maximum listed on the side of the tire (44 psi).
