Possible causes

The Ford Explorer was first offered for sale in March 1990. Ford internal documents 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. 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

The pound per square inch or, more accurately, pound-force per square inch is a unit of pressure or of stress based on avoirdupois units...

. The maximum pressure stamped into the sidewall of the tire was 35 psi; however tires should only be inflated to the pressure listed by the vehicle's manufacturer.

The failures all involved tread separation — the tread peeling off followed often by tire disintegration. If that happened, and the vehicle was running at speed, there was a high likelihood of the vehicle leaving the road and rolling over. 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, with not all occurring on Ford Motor Company vehicles. It is estimated that 119 of the 250 deaths resulted from a crash with a Ford Motor Company vehicle.

Ford and Firestone have both blamed the other for the failures, which has led to the severing of relations between the two companies. Firestone has claimed that they have found no faults in design nor manufacture, and that failures have been caused by Ford's recommended tire pressure being too low and the Explorer's design. Ford, meanwhile, point out that Goodyear tires to the same specification have a spotless safety record when installed on the Explorer, although an extra liner was included into the Goodyear design after recommendations to that effect were made to Ford. Firestone included an extra liner in its product and this was then also used to replace tires on Ford Explorers.

Many outside observers tend towards blaming both parties; 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.

 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.
A large number of lawsuits have been filed against both Ford and Firestone, some unsuccessful, some settled out of court, and a few successful. 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.

 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. However the results of this test were dubious since Car and Driver's test was for a very rapid deflation of the tire, when the accidents were caused by tread separation and not rapid deflation.
