•Narrower — to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, SUV’s and trucks often
will have a higher center of gravity
and a greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.
INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
New vehicles are fitted with tires
that have a rating on them called
Tire Quality Grades. The Quality
grades can be found where

example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
Tire Quality Grades apply to new pneumatic tires for use on passenger
cars. They do not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with nominal rim
diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Ford to give you the following
information about tire grades exactly as the government has written it.
Treadwear
The treadwear grade is a comparative rating based on the wear rate of
the tire when tested under controlled conditions on a specified
government test course. For example, a tire graded 150 would wear one

Temporary Emergency Spare Tire Information
Your vehicle may be equipped with a temporary emergency spare tire.
This tire may be a T-type/mini-spare tire which will have the words
“Temporary Use Only” molded into the tire sidewall or it may be a full
size dissimilar spare tire/wheel that is different in brand, size or
appearance from the road tire, which will be identified with a“Caution”
label on the wheel. Both of these spare tires are considered
“temporary”. Replace these temporary emergency spare tires on the
vehicle with a tire of the same size, speed rating and load carrying
capacity as the other road tires as soon as possible.
It is not recommended that the vehicle be operated in 4WD modes with
a temporary emergency spare tire. If 4WD operation is necessary, do not
operate above speeds of 10 mph (16 km/h) or for distances above 50 miles
(80 km).
When driving with the temporary emergency spare tire do not:
• Exceed 50 mph (80 km/h)
• Exceed 2000 miles (3200 km)
• Load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Certification Label
• Use snow chains
• Use more than one temporary emergency spare tire
• Use commercial car washing equipment
• Try to repair the temporary emergency spare tire
Use of a temporary emergency spare tire at any one wheel location can
lead to impairment of the following:
• Handling, stability and braking performance
• Comfort and noise
• Ground clearance and parking at curbs
• Winter weather driving capability
• Wet weather driving capability

risk of loss of vehicle control, injury or death.
Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel, then it is intended for temporary
use only. This means that if you need to use it, you should replace it as
soon as possible with a road tire/wheel that is the same size and type as
the road tires and wheels that were originally provided by Ford. If the
dissimilar spare tire or wheel is damaged, it should be replaced rather
than repaired.

•Exceed 70 mph (113 km/h)
•Use more than one dissimilar spare tire/wheel at a time
•Use commercial car washing equipment
•Use snow chains on the end of the vehicle with the dissimilar spare
tire/wheel
The usage of a dissimilar spare tire/wheel can lead to impairment of the
following:
•Handling, stability and braking performance
•Comfort and noise
•Ground clearance and parking at curbs
•Winter weather driving capability
•Wet weather driving capability
•All-Wheel driving capability (if applicable)
•Load leveling adjustment (if applicable)
When driving with the dissimilar spare tire/wheel additional caution
should be given to:
•Towing a trailer
•Driving vehicles equipped with a camper body
