Firestone and Ford tire controversy

The Firestone and Ford tire controversy was a period of unusually high tire failures on the Ford Explorer and related vehicles equipped with Firestone tires.

The Ford Motor Company had a historically strong relationship with Firestone since its inception, with Henry Ford and Harvey Samuel Firestone being personal friends and even the two families being linked in marriage with their respective grandchildren, William Clay Ford, Sr. and Martha Parke Firestone being married in 1947. United States-based Firestone became a subsidiary of Japanese tire manufacturer Bridgestone in 1988.

Problem detection[edit]

In May 2000, the U.S. National Highway Traffic Safety Administration (NHTSA) contacted Ford and Firestone about the high incidence of tire failure on Ford Explorers, Mercury Mountaineers, and Mazda Navajos fitted with Firestone tires. Ford investigated and found that several models of 15-inch Firestone tires (ATX, ATX II, and Wilderness AT) had very high failure rates, especially those made at Firestone's Decatur, Illinois plant. This was one of the leading factors to the closing of the Decatur plant.[1]

Joan Claybrook, who was the president of the public advocacy group Public Citizen and previously an Administrator of the NHTSA, stated before the Transportation Subcommittee United States Senate Committee on Appropriations on September 6, 2000, that, "there was a documented coverup by Ford and Firestone of the 500 defect".[citation needed] Also Clarence Ditlow; Executive Director for the Centre for Auto Safety in his statement before the Senate Committee on Commerce, Science and Transportation in Washington D.C., September 20, 2000[2] stated "Emerging Information shows that both Ford and Firestone had early knowledge of tread separation in Firestone Tires fitted to Ford Explorer vehicles but at no point informed the NHTSA of their findings". [3]

Possible causes[edit]

The Ford Explorer was first offered for sale in March 1990. Ford internal documents[citation needed] show the company engineers recommended changes to the vehicle design after it rolled over in company tests prior to introduction, but other than a few minor changes, the suspension and track width were not changed.[citation needed] Instead, Ford, which sets the specifications for the manufacture of its tires, decided to remove air from the tires, lowering the recommended pressure to 26 psi.[citation needed]

The failures all involved tread separation[4]—the tread peeling off followed often by tire disintegration.[citation needed] If that happened, and the vehicle was running at speed, there was a high likelihood of the vehicle leaving the road and rolling over.[citation needed] Many rollovers cause serious injury and even death; it has been estimated that over 250 deaths and more than 3,000 serious injuries resulted from these failures[citation needed], with not all occurring on Ford Motor Company vehicles.[5] It is estimated that 119 of the 250 deaths resulted from a crash with a Ford Motor Company vehicle[clarification needed].[5]

Some outside observers have speculated about the blame worthiness of both parties;[6] Firestone's tires being prone to tread separation and failure, and the SUVs being especially prone to rolling over if a tire fails at speed compared to other vehicles. A subsequent NHTSA investigation of real world accident data showed that the SUVs in question were no more likely to roll over than any other SUV, after a tread separation.[7]


A product recall was announced, allowing Explorer owners (and owners of its stablemates) to change the affected tires for others. Many of the recalled tires had been manufactured during a period of strike at Firestone.[8] A large number of lawsuits[citation needed] have been filed against both Ford and Firestone, some unsuccessful, some settled out of court, and a few successful.[citation needed] Lawyers for the plaintiffs have argued that both Ford and Firestone knew of the dangers but did nothing, and that specifically Ford knew that the Explorer was highly prone to rollovers. Ford denies these allegations.

Firestone ultimately recalled millions of tires including 2.8 million Firestone Wilderness AT tires.[9] According to Firestone's last filing with the National Highway Transportation Administration, only 90,259 of those tires were confirmed as removed from service.[10] In November 2013, two recalled Wilderness AT tires were found in Atlanta, Georgia.[11] One of the tires was offered for sale as new at a used tire retail shop.[12]

Following the recall, lawsuits were filed throughout the country. It was estimated that there had been over 250 deaths and 3,000 serious injuries. Because of the number of lawsuits the plaintiffs’ attorneys became concerned that the tire company would not have enough money to pay all of the claims and began looking for other sources of revenue. A principal target were the large tire sellers and services such as Sears, Roebuck and Co. [13]

Car and Driver magazine tested a first-generation Explorer with a built-in roll cage and a special device that would flatten the tire at the push of a button. While driven by professionals on a closed track, the Explorer did not flip in any of the numerous tests. The test differed substantially from real-world incidents in that the Car and Driver's test was for a very rapid deflation of the tire, while real-world accidents were caused by tread separation and not rapid deflation.[citation needed] Further, the tests were done on a flat straightaway while many fatal crashes occurred during highspeed cornering on highway cloverleaf ramps.[citation needed]

End and Re-Birth of Ford/Firestone relations[edit]

John T. Lampe (Chairman & CEO of Bridgestone/Firestone) announced in a 2001 letter to Jacques Nasser (Ford Motor Company chief executive) that Bridgestone/Firestone would no longer enter into new contracts with Ford Motor Company, effectively ending a 100-year supply relationship.[14]

The end was short-lived. Under Alan Mulally, Ford resumed business ties with Bridgestone, and Bridgestone now supplies tires for several Ford models and to Ford dealers.[citation needed]
