Tires, Wheels and Loading -> VEHICLE CHARACTERISTICS for Your Ford Explorer SUV Fifth Generation (2005-2011)

Tires, Wheels and Loading  
NOTICE TO UTILITY VEHICLE AND TRUCK OWNERS  
Utility vehicles and trucks handle  
differently than passenger cars in  
the various driving conditions that  
are encountered on streets,  
highways and off-road. Utility  
vehicles and trucks are not designed  
for cornering at speeds as high as  
passenger cars any more than  
low-slung sports cars are designed  
to perform satisfactorily under  
off-road conditions.  
WARNING: Utility vehicles have a significantly higher rollover  
rate than other types of vehicles. To reduce the risk of serious  
injury or death from a rollover or other crash you must:  
Avoid sharp turns and abrupt maneuvers;  
Drive at safe speeds for the conditions;  
Keep tires properly inflated;  
Never overload or improperly load your vehicle; and  
Make sure every passenger is properly restrained.  
WARNING: In a rollover crash, an unbelted person is  
significantly more likely to die than a person wearing a seat belt.  
All occupants must wear seat belts and children/infants must use  
appropriate restraints to minimize the risk of injury or ejection.  
Study your owner’s guide and any supplements for specific information  
about equipment features, instructions for safe driving and additional  
precautions to reduce the risk of an accident or serious injury.  
VEHICLE CHARACTERISTICS  
4WD and AWD Systems (if equipped)  
A vehicle equipped with AWD or 4WD (when selected) has the ability to  
use all four wheels to power itself. This increases traction which may  
enable you to safely drive over terrain and road conditions that a  
conventional two-wheel drive vehicle cannot.

Tires, Wheels and Loading  
Power is supplied to all four wheels through a transfer case or power  
transfer unit. 4WD vehicles allow you to select different drive modes as  
necessary. Information on transfer case operation and shifting procedures  
can be found in the Driving chapter. Information on transfer case  
maintenance can be found in the Maintenance and Specifications  
chapter. You should become thoroughly familiar with this information  
before you operate your vehicle.  
On some 4WD models, the initial shift from two-wheel drive to 4WD  
while the vehicle is moving can cause a momentary clunk and ratcheting  
sound. These sounds are normal as the front drivetrain comes up to  
speed and is not cause for concern.  
WARNING: Do not become overconfident in the ability of 4WD  
and AWD vehicles. Although a 4WD or AWD vehicle may  
accelerate better than two-wheel drive vehicle in low traction  
situations, it won’t stop any faster than two-wheel drive vehicles.  
Always drive at a safe speed.  
How your vehicle differs from other vehicles  
SUV and trucks can differ from  
some other vehicles in a few  
noticeable ways. Your vehicle may  
be:  
Higher – to allow higher load  
carrying capacity and to allow it  
to travel over rough terrain  
without getting hung up or  
damaging underbody components.  
Shorter – to give it the capability  
to approach inclines and drive  
over the crest of a hill without  
getting hung up or damaging  
underbody components. All other  
things held equal, a shorter  
wheelbase may make your vehicle  
quicker to respond to steering inputs than a vehicle with a longer  
wheelbase.

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  
Tire Quality Grades apply to new  
pneumatic passenger car tires. The  
Quality grades can be found where  
applicable on the tire sidewall  
between tread shoulder and  
maximum section width. For  
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 passenger car tires. They do  
not apply to deep tread, winter-type snow tires, space-saver or  
temporary use spare tires, light truck or “LT” type 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 Motor Company to give you  
the following information about tire grades exactly as the government  
has written it.
