Ford Explorer and the Tire Replacement Program: Myths & Facts
Myths & Facts About the Explorer
Myth: SUVs are unsafe because they roll over. SUV owners
would be better off driving cars.
Fact: That's false. Advances in safety
technology have made all types of passenger vehicles safer than the
vehicles on the road a generation ago. And Ford's analysis of
federal and state government safety data shows that, overall, SUVs
are even safer than passenger cars. That's because SUVs are
involved in fewer accidents - SUV drivers often have better lines of
sight and SUVs are more visible to other drivers. Also, SUV
occupants are often better protected when they are involved in
collisions.
Although SUVs are involved in more rollover crashes than
passenger cars, there is a greater risk of fatality in a passenger
car in frontal, side and rear impacts. As a result, SUVs are safer
overall.
SUVs do handle differently. That is a key reason that the
different handling characteristics are printed on a label appearing
on the visor of every SUV all automakers build.
Leading edge safety technology available later this year on the
2002 Ford Explorer - including AdvanceTracTM electronic stability
control and Ford's new Safety CanopyTM - will further reduce the
risk of a rollover and serious injury or death if a rollover
accident occurs. But a buckled safety belt is still the best and
primary line of defense for any adult occupant in a serious
accident. Children should of course be in the proper restraint
system (child seat, booster seat, etc.) until they are large enough
to use adult safety belts.
Myth: The Ford Explorer is more prone to roll over than
other SUVs.
Fact: Not true. Ford's analysis of safety data
from the U.S. Department of Transportation confirms that over the
past 10 years Explorer consistently ranks among the safest vehicles
in its class. The fatality rate for passenger cars is 1.5 per 100
million miles of vehicle travel. The rate for compact SUVs is lower
- 1.3. And the Explorer is even lower at 1.1.
Focusing on rollover accidents alone, the Explorer is safer than
competitive SUVs. Ford analysis of government safety data reveals
that the Explorer line is involved in 19 percent fewer fatal
rollovers than other similar SUVs. And, state safety data, which
covers fatal and non-fatal rollovers, show that Explorers are
involved in 16 percent fewer rollovers than competitive SUVs.
Myth: Ford launched this tire replacement effort to shift
blame away from the Explorer. Something is wrong with the Explorer,
but Ford wants people to think it's just a tire issue.
Fact: Not true. Ford Motor Company is replacing
these tires because its number one priority is to ensure the safety
of our customers and their families. Ford's concern is the
Wilderness AT tire. The facts are as follows:
First, Ford fitted both Firestone tires and Goodyear tires on
Explorers beginning in 1995 and through the 1997 model year. And
the difference in performance is dramatic. For the roughly 3
million Firestone tires equipped on about 500,000 Explorers,
Firestone's own claims database shows that there have been
1,183 claims of tread separation. For the 3 million Goodyear
tires on another 500,000 Explorers (that have traveled more than 25
billion miles), there have been only two minor claims
of tread separation according to claims information supplied by
Goodyear. The performance on the Firestone AT tires on Explorer is
600 times worse than Goodyear tires on Explorer. This remains
the only apples-to-apples comparison in this issue. If the
vehicle was the issue, or at the very least a contributing factor,
the tread separations between the Firestone and Goodyear tires would
be in the same ballpark. They are not even close. That's why Ford
is replacing the Firestone Wilderness AT tires.
Second, when Ford engineers tested the Wilderness AT tires over
the past nine months, they found that the tires were more sensitive
to stresses and consistently failed at higher rates, at lower speeds
and lighter loads than other tires tested, including the Goodyear
tires used on Explorer.
Third, the failure rates of Firestone Wilderness AT tires differ
dramatically based on the plant in which they were made. If the
vehicle were the cause of these separations, the tire plant location
would not make a difference in rate of tread separations reported.
Finally, Firestone CEO John Lampe testified last year before
Congress under oath and said the following: "We made some bad tires
and we take full responsibility for those." When a Senator asked,
"Are bad tires equated to be tires that have defects of some kind,"
Mr. Lampe responded, "Yes, sir."
Myth: The Firestone tires performed far better on the
Ranger than the Explorer. That's proof that the Explorer is part of
the reason for these tire failures.
Fact: The tires have performed better on Ranger,
however the Firestone tread separation claims on Ranger are still
higher than average. And, importantly, the Firestone tread
separation claims on Ranger are higher than Goodyear claims on
Explorer.
In the June 11, 2001-dated issue of Business Week, Brian O'Neill,
president of the Insurance Institute for Highway Safety, was asked
about the Explorer-Ranger comparison. He said, "It's an
apples-to-oranges comparison that has no validity in my
opinion."
Ford agrees with Mr. O'Neill. Tires used on any SUV perform
differently compared with tires installed on a pickup. The two
vehicles are used differently. SUVs typically weigh more, and
frequently are more heavily loaded, putting more stress on the
tires. A sensitive tire, like we have discovered with the
Wilderness AT, will not perform as well under these conditions.
Nevertheless, the larger-than-average numbers of tread separation
claims for Firestone tires on Rangers are proof - proof that
these tires should be replaced. This is why Wilderness AT tires on
Ranger are part of Ford's replacement campaign.
Myth: Even if the Explorer does not cause the tread
separation, it certainly is more likely to roll over as a result of
the tread separation.
Fact: Not true. Ford has conducted many tests
comparing Explorer with competitive SUVs and we have shared our
findings with the National Highway Traffic Safety Administration.
By inducing a tread separation at speeds approaching 70 mph on
Explorer and competitive vehicles, with various load conditions, the
Explorer's performance before, during and after a tread separation
was found to be typical of other SUVs. This exhaustive study was
shared with NHTSA and Firestone in March 2001.
The real-world accident experience shows when a Firestone tire
separated on an Explorer, a rollover accident occurred on average
less than 7 percent of the time. This information is based on
Firestone's own claims data. Government data show Explorer and
competitive SUVs have similar rollover experience in tire-related
accidents. Unfortunately, Firestone tires on Explorer have
separated with far greater frequency than tires on other SUVs and,
of course, Goodyear tires on Explorer. The two known Goodyear
tire separations, out of about 3 million Goodyear tires in service
on Explorers over the last six years, did not result in any
accidents, rollovers or injuries.
Myth: Safetyforum says that when tires fail on Explorers the
results are four times more likely to produce catastrophic rollover
than when they fail on other SUVs.
Fact: Ford's analysis of government data show that
the Explorer has a considerably better safety record than other SUVs
both in terms of fatal crashes and fatal rollover crashes.
Safetyforum is misinterpreting data by using unverified reports for
a variety of manufacturers. It's also misleading because it
compares the Explorer to all light trucks and not just competitive
SUVs.
Ford and the U.S. government use tire makers' claims data, not
this collection of unverified reports. Even Safetyforum, which is a
plaintiff's attorney resource organization, says they do not take
into account the tire model in their analysis. The fact is that
Ford's testing shows Explorers perform like other SUVs before,
during and after a tire tread separation, and real world safety data
show that Explorer is among the safest vehicles on the road year
after year.
Myth: Internal memos show that Ford knew about the
instability of the Explorer years ago and did nothing.
Fact: That's just plain wrong. The Explorer team
sought to develop a safe vehicle, recognizing that safety
performance among the leaders in its class would help it to become
the sales leader. And that's just what they accomplished - over the
past 10 years Explorer consistently has ranked among the safest
vehicles in its class based on Ford's analysis of the Federal
government's real world database of crash statistics. And Explorer
has been the best-selling SUV in the world each year.
Memos from engineers working on the original Explorer show them
working hard to make it a safety leader, and sweating over small
changes necessary for prototype vehicles to pass Ford's stringent
internal safety tests that ensure safe, predictable vehicle
responses in severe "limit handling" maneuvers. And yes, from time
to time, they debated among themselves in their search for the
optimum solutions. That is what our engineers get paid to do. If
any version of those prototypes didn't pass every stringent test,
changes were made until they did. That's exactly why prototypes are
built. By the time the first Explorer was driven by the first
customer on a real road, the vehicle had passed all of Ford's
internal safety tests.
Myth: Ford has spent a lot of time looking at tires as the
root cause of the problem and has done little to evaluate Explorer
handling due to tire separation and rollover. It seems odd that
Ford has relied solely on government data for its
analysis.
Fact: While important, government data is not the
only part of the evaluation of the Explorer. On March 28 and 29,
2001, Ford presented NHTSA with an exhaustive analysis of Explorer.
(This technical analysis is available from NHTSA.) The analysis
included stringent on-road and computer-aided testing of the
Explorer and comparative SUVs in its class. The analysis dissected
the performance of every major component of the Explorer that has
anything to do with ride and handling, including emergency handling
maneuvers and tread separation of the tires. Contrary to recent
Firestone charges, it is a fact that Firestone received this
thorough analysis from Ford on March 30, 2001. |
