What's Behind the Firestone
Steeltex Recall on Ford Excursions?

July 2004
In
February 2004 Firestone found itself in the headlines again when it agreed to
recall 497,000 Steeltex tires that were predominantly installed as original
equipment on 2000 through early model 2003 Ford Excursions (04T-003). While no specific defect pattern was noted,
the tires experienced sidewall failures, tread separations, blowouts and
unexplained loss of pressure and caused at least six crashes involving five
deaths. The Steeltex line covers a
number of different tire types and sizes, those subject to the recall include
only the Radial AT size LT265/75R16, Load Range D manufactured in the Joliette,
Quebec plant during March 1999 through December 2002 and installed on Ford
Excursions.
The
Steeltex recall is unusual on two fronts.
NHTSA, Bridgestone/Firestone and Ford all credited the recall to the use
of the Early Warning Reporting data that was required by Congress following the
Ford / Firestone controversy in 2000.
This is the first recall to result from the use of the EWR data and is
widely being touted as a successful test of the system even by agency
critics. According to NHTSA personnel
and published reports, the agency examined the EWR data it received from Ford
and Firestone and determined that the AT version of the Steeltex in a load
range D fitted on Excursions, Ford’s largest SUV, showed a failure rate that
raised “concern.” The agency’s initial
evaluation of the EWR led to direct communications with Ford and Firestone and
a suggestion a recall was in order. In
what appears to have been successful negotiations Firestone agreed to recall
the allegedly defective tires. However,
the nature of the negotiations, the lack of a formal investigation, and EWR
data that is still not (and may never be) available for public scrutiny leads to
a healthy dose of skepticism by some NHTSA-watchers. If the Steeltex recall represents a success, the data and
rationale should be made available for review.
Keeping the data and analysis secret, information that is normally
included in defect investigations, makes the process a closed one. Public access to this information is rendered
more important because there are no specific guidelines for recalls and there
are often conflicting precedents.
A
review of the Steeltex recall also reveals what appears be a Ford problem that
under NHTSA statute foists the entire burden on Firestone. Tires, even those that are specified by a
vehicle manufacturer for OE application, unlike other component parts, are the
sole responsibility of the tire manufacturer.
Thus the recall burden fell on Firestone, despite what appears to be
tires that were specified with too low a margin of safety. The recalled tires are being replaced with a
higher load range tire (Load Range E)--the same tire used on the Ford F250/350,
which shares its platform with the Excursion.
The lack of a specific failure pattern, a higher failure rate on a size
used almost exclusively on Ford Excursions, and statements from Firestone that
many of the failures occurred due to overloading all suggest Ford’s
specification of an inadequate load range.
Tire experts familiar with the situation concur that this is likely. The use of a lower load range left the Excursion
with a margin of safety that was too low, harkening back to Ford's decisions for
the Wilderness and ATX on the Explorer.
The
Steeltex tire line has been under scrutiny following the ATX / Wilderness
investigation by NHTSA and lawyers.
While there is an inherent discomfort to stand behind the safety of any
Firestone tire, particularly those made during the 1990s when the company
instituted major cost cutting programs, the claims data reviewed by NHTSA did
not raise to the level at which an investigation or recall appeared
warranted.
