What was the core issue of the Firestone and Ford tire controversy in the 1990s?

The Firestone and Ford tire controversy centered on the unusually high failure rates of specific Firestone tires installed on Ford light trucks and SUVs, particularly the Ford Explorer. These failures, primarily tread separations, led to numerous automobile crashes.

Which specific Firestone tire models were most frequently implicated in the controversy?

The Firestone tire models most frequently implicated were the P235/75R15 ATX, ATX II, and Wilderness AT tires. These were commonly installed as original equipment on various Ford and Mercury vehicles.

What were the reported consequences of the Firestone tire failures in the United States?

In the United States alone, the failures of these Firestone tires were linked to approximately 238 deaths and around 500 injuries due to automobile crashes. More fatalities occurred in other countries as well.

How did the controversy impact Firestone's parent company, Bridgestone, and its relationship with Ford?

The revelations surrounding the tire failures caused the market value of Bridgestone, Firestone's parent company, to be halved. The disagreement over blame led to the end of the nearly 100-year business relationship between Ford and Firestone, with both companies seeing executive resignations or firings.

What information did the Arizona state government provide to Firestone regarding its tires in 1996?

In 1996, the Arizona state government informed Firestone that the treads on its tires were separating, particularly at high speeds and in high temperatures. Firestone responded by sending engineers to inspect the tires and subsequently replaced them with heavier-duty ones, attributing the issues to improper usage.

What did internal Firestone documents reveal about injury claims related to specific tire models in 1997?

By 1997, internal Firestone documents indicated a rise in injury claims specifically concerning the ATX, ATX II, and Wilderness AT tire models, suggesting the company was aware of increasing problems.

How did Samuel Boyden contribute to the investigation of Firestone tire failures?

Samuel Boyden, a researcher for State Farm Insurance, identified 21 crashes caused by Firestone tire tread separation in 1998 and forwarded this information to NHTSA. He later found an additional 30 cases in 1999, which he also reported to NHTSA, thus bringing more evidence to the agency's attention.

In which international locations did Ford take action regarding Firestone tires before the major US recall?

Ford began replacing Firestone tires in Venezuela in 1998 due to 46 reported deaths. Additionally, a Ford dealer in Saudi Arabia noticed high failure rates in 1997 and began replacing Firestone tires on unsold vehicles and offering discounts for replacements during maintenance.

What was the nature of the limited recall undertaken by Ford and Firestone in 1999 and spring 2000?

Ford and Firestone conducted a limited recall of tires in the Middle East, Venezuela, Malaysia, and Thailand during 1999 and the spring of 2000. However, crucially, NHTSA was not notified about this recall effort.

What significant media report brought wider public attention to the Firestone tire failures in early 2000?

In February 2000, KHOU-TV in Houston, Texas, aired a nine-minute report detailing high-speed Firestone tire failures on Ford Explorers that had resulted in 30 deaths. The report generated a significant public response, with the station directing concerned callers to NHTSA.

What did Clarence Ditlow of the Center for Auto Safety state regarding Ford and Firestone's knowledge of tire defects?

Clarence Ditlow informed the Senate Committee on Commerce, Science, and Transportation that emerging information indicated both Ford and Firestone possessed early knowledge of tread separation issues in Firestone tires fitted to Ford Explorers but had not reported these findings to NHTSA.

Why did Firestone fail to act on its internal data regarding tire failures?

Firestone possessed more information about tire failures than Ford due to warranty claims, but it did not act on this data because it consistently blamed consumers for improper tire maintenance or operating vehicles in extreme conditions. This perspective led them to believe the failures were not due to defects.

How did the consumer complaint reporting system potentially obscure the scale of the tire problem?

When Ford and NHTSA reviewed consumer complaints, they relied on NHTSA's toll-free hotline. However, attorneys and their clients had largely stopped using the hotline to report tire failures, meaning the complaint data did not accurately reflect the true extent of the problem.

When did NHTSA initiate its investigation into the Firestone tire failures, and what was the scope?

NHTSA began a preliminary inquiry into the high incidence of tire failures and accidents involving Ford Explorers and other light trucks and SUVs fitted with Firestone Radial ATX, ATX II, and Wilderness tires on March 6, 2000. This inquiry was formally upgraded to an investigation (PE00-020) on May 2, 2000.

What were the main arguments presented by Firestone and Ford to NHTSA regarding the causes of the tire failures?

Firestone argued that vehicle weight, tire design, low recommended inflation pressure, and manufacturing issues at the Decatur factory contributed to the failures. Ford countered that the tire design resulted in higher operating temperatures than comparable tires, that Firestone tires had a weaker wedge strip, and that manufacturing problems existed at the Decatur factory.

What changes did Ford make to the Explorer's design for the 2002 model year to address safety concerns?

For the 2002 model year, Ford redesigned the Explorer. Key changes included raising the tire pressure to 30 psi, widening the wheelbase by 2.5 inches, lowering the suspension, and adding independent rear suspension and electronic stability control.

What was the temperature and heat resistance rating of the Wilderness AT tires, and what did this rating imply?

The Wilderness AT tires had a temperature and heat resistance rating of 'C', which is the lowest rating permitted by the NHTSA's Uniform Tire Quality Grading System. This indicated a reduced capacity to handle heat buildup compared to tires with higher ratings.

Which Firestone manufacturing plant produced tires with a significantly higher failure rate?

The Firestone plant located in Decatur, Illinois, produced tires with a significantly higher failure rate compared to the other factories that manufactured the same tire models, namely Wilson, North Carolina, and Joliette, Quebec.

What was the primary mechanism of failure for the implicated Firestone tires?

The failures primarily involved tread separation, where the tire's tread peeled away from the main body of the tire. This issue has been a known challenge in radial tire design since their development.

How did the design of the Firestone tires contribute to tread separation?

The failures often began as belt-edge separation at the second belt, an area of high strain due to the transition from steel to rubber. The design of the belt wedge, which is a strip of rubber between the steel belts, was often insufficient on these tires, particularly before May 1998, failing to resist crack formation and growth.

What factors were identified as primary causes for the tread separations?

Several primary causes were identified: tire age, the specific manufacturing facility (particularly Decatur, Illinois), operating temperature, tire design flaws (like the wedge gauge and shoulder pocket), and labor and management problems within Bridgestone/Firestone.

How did tire aging impact the Firestone tires involved in the controversy?

As tires aged, changes in the belt wedge and skim rubber compounds reduced their ability to resist crack growth and belt separation. Most tread separations occurred on tires that had been in service for at least three years, with tires from the Decatur plant showing earlier failure times.

What manufacturing difference was noted at the Decatur factory that might have contributed to tire failures?

The primary manufacturing difference at the Decatur factory was in the early material mixing stages, resulting in materials with differing percentages of processing lubricant. While this was noted, there was insufficient evidence to definitively conclude it weakened the tires.

How did operating temperature influence tire failure rates?

Higher operating temperatures, caused by factors like increased vehicle load, speed, and ambient air temperature, accelerate the aging of tire materials. Tires used in warmer climates showed less ductility and higher failure rates, even with minimal tread wear, suggesting temperature was a significant factor.

What was the significance of the vehicle load in relation to tire failures?

Vehicle load was identified as the single most important factor among four analyzed that influenced the growth of cracks within the tires. Higher loads increased the rate at which these cracks grew, potentially leading to premature failure.

Why did Ford Explorers experience more tire failures than Ford Rangers, even when using the same tire models?

Ford Explorers had more tire failures than Ford Rangers because the Explorer weighed more and had a higher Gross Vehicle Weight Rating (GVWR) while using a lower recommended tire pressure (26 psi). This combination increased stress on the tires compared to their use on lighter Ranger trucks.

What specific design flaw was identified in the Wilderness AT tires manufactured before May 1998?

Wilderness AT tires manufactured before May 1998 had an inter-belt gauge (a strip of rubber between the steel belts) that was often thinner than Firestone's minimum specification and also thinner than comparable tires from other manufacturers. This design was not robust enough to resist crack formation and growth.

What did Bridgestone's acquisition of Firestone in 1988 lead to in terms of company pressure?

After purchasing Firestone, Bridgestone, facing significant debt and Firestone's financial losses, pressured Firestone to cut manufacturing and labor costs. Critics and workers alleged this pressure led to corner-cutting in production and the acceptance of substandard tires.

What specific concessions did Firestone demand from the United Rubber Workers (URW) in 1994?

Firestone demanded significant concessions, including a switch to 12-hour shifts, a 30% pay cut for new hires, a seven-day workweek, employee contributions to healthcare, a move from piece-rate to performance-based pay, and a reduction in vacation time for senior workers.

What was the impact of the URW strike and replacement workers on tire quality at the Decatur plant?

Studies suggest that labor unrest, including strikes and the use of replacement workers, can reduce the quality of production. Tires manufactured during critical periods of the strike and subsequent labor disputes at the Decatur plant showed higher failure rates compared to periods of stable labor relations.

What was the estimated cost of Firestone's recall of tires in Venezuela?

The recall of 62,000 Venezuelan-made Firestone tires in August 2000 was estimated to cost $6 million.

What was the scope of Firestone's major recall announced on August 9, 2000?

Firestone recalled approximately 6.5 million tires, including all ATX and ATX II tires and ATX/ATX II tires manufactured after 1991 and 1996 respectively. However, the recall for Wilderness AT tires was limited to those manufactured at Firestone's Decatur plant.

What was the total number of Firestone tires recalled by Ford in May 2001, and what was the estimated cost to Ford?

Ford voluntarily recalled an additional 13 million Firestone Wilderness AT tires in May 2001 that were not covered by the original recall. This action cost Ford an estimated $3 billion.

What did NHTSA mandate in October 2001 regarding Wilderness AT tires?

NHTSA mandated a recall of 3.5 million P235/75R15 and P255/70R16 Wilderness AT tires manufactured before May 1998, specifically those assembled in the Joliette, Quebec, or Wilson, North Carolina factories. This action removed all remaining Wilderness AT tires with the earlier, less robust design.

According to NHTSA data as of September 2001, how many fatalities and injuries were attributed to the tire failures?

As of September 2001, NHTSA reported that 271 people were killed and over 500 injured in the United States due to Firestone tire failures. Of these, 192 fatalities were linked to tread separation, 33 to blowouts, and 33 to unknown tire failure modes.

What was the estimated financial impact of the controversy on Ford and Firestone?

It is estimated that the tire failures and rollovers cost Bridgestone/Firestone approximately $1.67 billion and Ford Motor Company $530 million. Bridgestone's market price dropped by 50%, and its restructuring cost $2 billion, while Ford recorded a $5.5 billion loss in 2001.

What were the primary arguments made by plaintiffs' lawyers in lawsuits against Ford and Firestone?

Plaintiffs' lawyers argued that both Ford and Firestone were aware of the dangers associated with the tires and the Explorer's design but failed to act. Specifically, they contended that Ford knew the Explorer was highly prone to rollovers, while Firestone argued Ford's recommended tire pressure was too low and the Explorer was inherently dangerous.

What was the outcome of the congressional investigation into the tire controversy?

The congressional investigation, which began in September 2000, examined why NHTSA was slow to identify the defects and why Ford and Firestone delayed reporting known issues. This investigation directly led to the passage of the TREAD Act.

How did the public dispute between Ford and Firestone escalate, leading to the end of their business relationship?

Relations soured when Ford accused Firestone of withholding data, and Firestone accused Ford of withholding safety data on the Explorer. This culminated in Firestone's CEO informing Ford in May 2001 that they would no longer enter new contracts, effectively ending their century-long relationship, while also calling for an investigation into the Explorer's design flaws.

What corporate leadership changes occurred at Bridgestone/Firestone and Ford as a result of the controversy?

Masatoshi Ono resigned as Chairman and CEO of Bridgestone/Firestone in October 2000, replaced by John Lampe. Yoichiro Kaizaki, CEO of Bridgestone, resigned in January 2001. The public conflict also contributed to Ford firing its CEO, Jacques Nasser, in November 2001.

What was the ultimate fate of Firestone's Decatur, Illinois plant?

Firestone closed its Decatur plant in December 2001, laying off all 1,500 employees. The company cited declining consumer demand for Firestone tires and the plant's age as reasons for the closure, which cost Bridgestone/Firestone an estimated $210 million.

The Problem

Catastrophic Failures

The Firestone and Ford tire controversy of the late 1990s involved hundreds of fatalities and injuries resulting from the failure of Firestone tires installed on Ford Motor Company light trucks and SUVs. Specifically, unusually high failure rates of P235/75R15 ATX, ATX II, and Wilderness AT tires on the first-generation Ford Explorer led to crashes that claimed numerous lives and injured hundreds more in the United States and internationally.^[1]

Early Detection & Delayed Action

As early as 1996, personal injury lawyers were aware of accidents, injuries, and deaths linked to tread separation in Firestone tires at high speeds. However, researchers and lawyers hesitated to contact the National Highway Traffic Safety Administration (NHTSA), fearing that an official investigation might compromise ongoing lawsuits. This delay meant that the majority of the 271 known deaths attributed to these tires occurred after 1996.^[3]

Global Impact

While statistics focused on the United States, the problem extended globally. Reports indicated significant numbers of deaths in countries like Venezuela, and Ford dealerships in places like Saudi Arabia began proactively replacing Firestone tires due to observed high failure rates starting in 1997.^[2]^[8]

Contributing Causes

Manufacturing & Labor Issues

The Decatur, Illinois, Firestone factory, where many of the defective tires were produced, exhibited higher failure rates compared to other Firestone plants. This was potentially linked to labor unrest, including a significant strike and the subsequent hiring of replacement workers. Testimonies from former workers suggested issues with quality control, such as inadequate inspection rates and potential contamination or damage during the manufacturing process.^[1]^[28]^[29]

Operating Conditions & Tire Age

Tire operating temperature, influenced by vehicle load, speed, ambient temperature, and inflation pressure, played a critical role. Lower inflation pressures, like the 26 psi recommended by Ford for the Explorer, increased tire temperatures and accelerated aging, particularly in warmer climates. Most failures occurred on tires that were at least three years old, suggesting that material degradation combined with operating stress led to failures.^[37]

Tire Design Flaws

Specific design elements of the Firestone ATX, ATX II, and Wilderness AT tires were identified as contributing factors. Issues included a potentially undersized rubber wedge between steel belts, inadequate inter-belt gauge, and shoulder pockets that could lead to stress concentrations and crack formation. These design weaknesses made the tires more susceptible to tread separation, especially under the demanding conditions often experienced by SUVs.^[15]

The Ford Explorer's Role

Design Compromises

Ford designed the first-generation Explorer by mounting an SUV body on a lighter pickup truck chassis (Ford Ranger). This approach, while cost-effective, resulted in a higher center of gravity and a suspension system prone to swaying, making the vehicle more susceptible to rollovers, especially after a tire failure. Ford's decision to lower the recommended tire pressure to 26 psi for a smoother ride further exacerbated the issue by increasing tire operating temperatures.^[20]

Redesign and Stability Control

Following the controversy, Ford redesigned the Explorer for the 2002 model year. Changes included raising tire pressure to 30 psi, widening the wheelbase, lowering the suspension, and importantly, adding independent rear suspension and electronic stability control (ESC) systems to improve handling and mitigate rollover risks.^[20]^[27]

Handling Dynamics

Firestone argued that the Explorer's design, particularly its tendency towards oversteer following a rear tire tread separation, contributed significantly to the severity of accidents. While NHTSA initially suggested that such handling characteristics were not necessarily indicative of a defect, the subsequent redesign of the Explorer aimed to address these concerns directly.^[26]

The Firestone Tires

Tread Separation Mechanism

The core issue was tread separation, where the tire's tread peeled away from the main body. This failure mode often began as a separation at the edge of the second steel belt, an area of high stress in radial tires. Over time and under stress, cracks could grow, leading to catastrophic failure, particularly at higher speeds due to centrifugal forces.^[30]^[31]^[32]

Specific Models and Defects

The primary tires involved were Firestone P235/75R15 ATX, ATX II, and Wilderness AT models. These were installed as Original Equipment (OE) on various Ford and related vehicles. Wilderness AT tires manufactured before May 1998, in particular, were identified as having a design defect related to the belt wedge thickness, making them more prone to failure.^[15]

Heat Resistance and Load

Wilderness AT tires had a temperature resistance rating of "C," the lowest allowed by NHTSA standards. Higher operating temperatures, exacerbated by vehicle load and lower inflation pressures, significantly increased the rate of aging and susceptibility to crack growth, even on tires with minimal tread wear.^[15]

The Recall Process

Initial Recalls and Hesitation

Ford began replacing Firestone tires in Venezuela and Saudi Arabia as early as 1998-1999 due to observed issues. Firestone issued a recall for 6.5 million ATX and ATX II tires, and specific Wilderness AT tires, in August 2000. However, this recall initially excluded Wilderness AT tires from other manufacturing locations, leading to further scrutiny.^[53]^[54]

Ford's Expanded Recall

Concerns about NHTSA potentially deeming remaining Wilderness AT tires unsafe prompted Ford to initiate its own voluntary recall in May 2001, covering an additional 13 million Firestone tires across various sizes. This move significantly escalated the cost and public nature of the crisis.^[2]

Mandatory Recall & NHTSA Action

In October 2001, NHTSA issued a mandatory recall for 3.5 million P235/75R15 and P255/70R16 Wilderness AT tires manufactured before May 1998, citing the design defect in the belt wedge. This action effectively removed all remaining tires with that specific vulnerability from service.^[55]

The Fallout

Fatalities and Injuries

By September 2001, NHTSA reported approximately 271 fatalities and over 500 injuries in the U.S. attributed to the tire failures. The majority of these incidents occurred in states with high temperatures like California, Arizona, Texas, and Florida. An additional 46 deaths were reported in Venezuela.^[57]

Financial Costs and Settlements

The crisis imposed immense financial burdens. Bridgestone/Firestone incurred costs estimated at $1.67 billion, while Ford spent approximately $530 million. Settlements for personal injury lawsuits were substantial, with fatality cases reportedly settling between $4 million and $8 million, and paralysis cases between $12 million and $16 million. Firestone also set aside $800 million for lawsuits, and Ford spent $590 million on settlements.^[72]^[59]

Congressional Scrutiny & TREAD Act

The scandal triggered congressional hearings in September 2000, questioning the delayed discovery of defects and the lack of timely reporting to NHTSA by both companies. This investigation directly led to the enactment of the Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act in October 2000, strengthening vehicle safety regulations and recall procedures.^[65]

Severed Corporate Ties

The public dispute and differing views on responsibility fractured the century-long relationship between Ford and Firestone. In May 2001, Bridgestone/Firestone announced an end to future contracts with Ford, citing safety concerns with the Explorer. This public declaration preceded Ford's expanded recall announcement.^[66]

Executive Changes

The controversy led to significant personnel changes at the highest levels. Bridgestone/Firestone saw the resignation of its chairman, CEO, and president. The fallout also contributed to the dismissal of Ford's CEO, Jacques Nasser, in November 2001.^[67]^[68]^[69]

Plant Closure

Firestone's Decatur, Illinois, plant, identified as a major source of the defective tires, was closed in December 2001, resulting in the layoff of 1,500 employees. Firestone cited declining demand and the plant's age as reasons, though the closure followed intense scrutiny related to quality control during labor disputes.^[70]^[71]
