  • The Recall of Firestone Tires

    3108 Words  | 7 Pages

    In August 2000, there was a recall of Bridgestone/Firestone tires. The company recalled its 15 inch ATX and ATX II tires, plus 15 inch Wilderness AT tires. The recall involved more than six million tires. A federal investigation found at least 88 deaths and more than 300 accidents involving Bridgestone/Firestone tires that had shredded on the highway. The majority of the accidents held the same situation of the driver maintaining a speed of 65 miles per hour, the tires shredded and the rubber peeled away from the rim. Most of the tire failures involved Ford Explorer sport utility vehicles. These accidents occurred after tire treads peeled off, causing tires to burst and malfunction then drivers lost control of their vehicles which resulted in crashes and turnovers. The tires involved are made up of many different materials layered around an inner shell. The outermost layer is the tread, which covers two layers of steel cords. This tire recall was the second largest in history; it also raised a significant social responsibility and ethical issues for both Ford and Bridgestone/Firestone companies. Firestone's last major tire recall nearly bankrupted the company in 1978, and led to its acquisition by Japanese-based Bridgestone. As with the recall announced, it involved abnormally high tread separation, resulting in accidents and deaths. Most of the tires involved in the recall were produced at Firestone's Decatur, Illinois plant. Poor quality was named as one of the main causes of the failures, and many proposals were advanced to strengthen and update regulatory procedures.
