or suspected have the tire
inspected by a tire professional.
Tires can be damaged during
off-road use, so inspection after
off-road use is also
recommended.
Age
WARNING
Tires degrade over time depending
on many factors such as weather,
storage conditions, and conditions
of use (load, speed, inflation pressure, etc.)
the tires experience throughout their lives.
In general, tires should be replaced after
six years regardless of tread wear.
However, heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process and may
require tires to be replaced more
frequently.
You should replace your spare tire when
you replace the road tires or after six years
due to aging even if it has not been used.
U.S. DOT Tire Identification Number
(TIN)
Both U.S. 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
(affixed to either the door hinge pillar,
door-latch post, or the door edge that
meets the door-latch post, next to the
driver's seating position), or the Tire Label
which is located on the B-Pillar or edge of
the driver’s door. If this information is not
found on these labels then you should
contact your authorized dealer as soon as
