There was a very high failure rate in Firestone's "Wilderness AT", "Firestone ATX", and "ATX II" tires. Several lawsuits were filed. There was a mandatory recall of the tires. In 2001 Bridgestone Firestone stopped working with Ford because they did not trust Ford. They said Ford had not listened to warnings by Bridgestone Firestone about the design of the Ford Explorer. In 2006, Firestone announced a new effort to recall the same tires recalled in 2000. More of the tires had been linked to recent deaths and injuries. Firestone estimates 97% of the tires were replaced in the 2000 recall. They are still concerned over spare tires that owners did not think to replace.
