U.S. DOT Tire Identification Number
Both United States and Canada Federal
regulations require tire manufacturers
to place standardized information on the
sidewall of all tires. This information
identifies and describes the fundamental
characteristics of the tire and also
provides a U.S. DOT Tire Identification
Number for safety standard certification
and in case of a recall.
This begins with the letters DOT and
indicates that the tire meets all federal
standards. The next two numbers or
letters are the plant code designating
where it was manufactured, the next two
are the tire size code and the last four
numbers represent the week and year
the tire was built. For example, the
numbers 317 mean the 31st week of
1997. After 2000 the numbers go to four
digits. For example, 2501 means the
25th week of 2001. The numbers in
between are identification codes used
for traceability. This information is used
to contact customers if a tire defect
requires a recall.
Tire Replacement Requirements
Your vehicle is equipped with tires
designed to provide a safe ride and
handling capability.
WARNINGS
Only use replacement tires and
wheels that are the same size, load
index, speed rating and type (such as
P-metric versus LT-metric or all-season
versus all-terrain) as those originally
provided by Ford. The recommended
tire and wheel size may be found on
either the Safety Compliance
Certification Label or the Tire Label. If
this information is not found on these
labels then you should contact your
authorized dealer as soon as possible.
Use of any tire or wheel not
recommended by Ford can affect the
safety and performance of your vehicle,
which could result in an increased risk
of loss of vehicle control, vehicle
rollover, personal injury and death.
Additionally the use of
WARNINGS
non-recommended tires and wheels
could cause steering, suspension, axle,
transfer case or power transfer unit
failure. If you have questions regarding
tire replacement, contact your
authorized dealer as soon as possible.
To reduce the risk of serious injury,
when mounting replacement tires
and wheels, you should not exceed the
maximum pressure indicated on the
sidewall of the tire to set the beads
without additional precautions listed
below. If the beads do not seat at the
maximum pressure indicated,
re-lubricate and try again.
When inflating the tire for mounting
pressures up to 20 psi (1.38 bar) greater
than the maximum pressure on the tire
sidewall, the following precautions must
be taken to protect the person mounting
the tire:
1. Make sure that you have the correct
tire and wheel size.
