FORD 2013 Escape v.1 - Manual (Page 253)

When the tread is worn down to one
sixteenth of an inch (2 mm), tires must be
replaced to help prevent your vehicle from
skidding and hydroplaning. Built-in
treadwear indicators, or wear bars, which
look like narrow strips of smooth rubber
across the tread will appear on the tire
when the tread is worn down to one
sixteenth of an inch (2 mm)
When the tire tread wears down to the
same height as these wear bars, the tire is
worn out and must be replaced.
Damage
Periodically inspect the tire treads and
sidewalls for damage (such as bulges in
the tread or sidewalls, cracks in the tread
groove and separation in the tread or
sidewall). If damage is observed 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
