2003 FORD RANGER tires

•Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle, including occupants and cargo, is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
•Trailer Weight Range:Specified range of trailer weight from zero to
the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
The Safety Certification Label, located on the driver’s door pillar, lists
vehicle weight rating limitations. Before adding any additional equipment,
refer to these limitations.
Always ensure that the weight of occupants, cargo and equipment is
within the weight limitations, including both gross vehicle weight and
front and rear gross axle weight rating limits.
Note:Do not exceed the GVWR or the GAWR specified on the
certification label.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle, loss of vehicle control, vehicle
rollover, and/or personal injury.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle’s GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
this chapter.
Loaded vehicles may handle differently than unloaded vehicles.
Extra precautions, such as slower speeds and increased stopping
distance, should be taken when driving a heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.

Calculating the load your vehicle can carry/tow
1. Use the appropriate maximum GCWR chart (in theTrailer Towing
section in this chapter) for your type of engine and rear axle ratio.
2. Weigh your vehicle without cargo. To obtain correct weights, take your
vehicle to a shipping company or an inspection station for trucks.
3. Subtract your loaded weight from the maximum GCWR in the chart.
This is the maximum trailer weight your vehicle can tow. It must be
below the maximum trailer weight shown in the chart.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle’s engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully after any towing operation.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
The use of tire sealants is not recommended and may
compromise the integrity of your tires.
Temporary spare tire information
Your vehicle is equipped with a conventional spare tire that may be
different in size (smaller diameter and narrower width) than other tires
on your vehicle. If this is the case, your spare tire is considered
“temporary”and the spare wheel will be labeled as such. Replace this
tire 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”(i.e. dissimilar size) spare. If 4WD operation is necessary,
do not operate above speeds of 16 km/h (10 mph) or for distances above
80 km (50 miles).
Roadside Emergencies
158

If you use the temporary spare tire continuously or do not follow
these precautions, the tire could fail, causing you to lose control
of the vehicle, possibly injuring yourself or others.
When driving with the temporary spare tiredo not:
•exceed 80 km/h (50 mph) or drive further than 3,200 km (2,000
miles) total under any circumstances
•load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
•tow a trailer
•use more than one temporary spare tire at a time
Use of a temporary 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 driving capability
Conventional spare tire information
If you have the conventional spare tire that is the same size as your
other road tires, you can use the spare as you would any of the other
tires. The spare tire will be equivalent to your road tires, although it may
not have the same appearance (black-side wall instead of outlined-white
letters).
Roadside Emergencies
159

•Combine errands and minimize stop-and-go driving.
Maintenance
•Keep tires properly inflated and use only recommended size.
•Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
•Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
•Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
•Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
•Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
•Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
•Using fuel blended with alcohol may lower fuel economy.
•Fuel economy may decrease with lower temperatures during the first
12–16 km (8–10 miles) of driving.
•Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
•Transmissions give their best fuel economy when operated in the top
cruise gear and with steady pressure on the gas pedal.
•Four-wheel-drive operation (if equipped) is less fuel efficient than
two-wheel-drive operation.
•Close windows for high speed driving.
EPA window sticker
Every new vehicle should have the EPA window sticker. Contact your
dealer if the window sticker is not supplied with your vehicle. The EPA
window sticker should be your guide for the fuel economy comparisons
with other vehicles.
It is important to note the box in the lower left corner of the window
sticker. These numbers represent the Range of L/100 km (MPG)

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
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 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
and one-half (1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
The traction grades, from highest to lowest are AA, A, B, and C. The
grades represent the tire’s ability to stop on wet pavement as measured
under controlled conditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor traction
performance.
Maintenance and Specifications
224

The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include
acceleration, cornering, hydroplaning or peak traction characteristics.
Temperature A B C
The temperature grades are A (the highest), B and C, representing the
tire’s resistance to the generation of heat and its ability to dissipate heat
when tested under controlled conditions on a specified indoor laboratory
test wheel. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
The temperature grade for this tire is established for a tire that
is properly inflated and not overloaded. Excessive speed,
underinflation, or excessive loading, either separately or in
combination, can cause heat buildup and possible tire failure.
SERVICING YOUR TIRES
Checking the tire pressure
•Use an accurate tire pressure gauge.
•Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km (3
miles).
•Adjust tire pressure to recommended specifications found on the
Certification Label. Tire pressure information can also be found on the
Tire Information label located on the inside of the fuel filler door.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control, vehicle
rollover and/or personal injury.
Tire rotation
Because your vehicle’s tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
Maintenance and Specifications
225

them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
The following procedure applies to vehicles equipped with single rear
wheels, if your vehicle is equipped with dual rear wheels it is
recommended that only the front wheels be rotated (side to side).
•Four tire rotation
•Five tire rotation
