The National Highway Traffic Safety Administration (NHTSA) concluded on Oct. 4 that many Firestone Wilderness AT tires built before 1998 contain a safety defect. NHTSA also stated that Firestone made changes in the tire in 1998, but “because tread separation failures rarely occur in these tires until at least 3 years of use, NHTSA cannot determine whether their actual field performance is significantly better than the older (recalled) tires. NHTSA will continue to monitor the field performance.”
