tire size FORD EXCURSION 2003 1.G Owners Manual

Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
Do not use a size and type of tire and wheel other than that
originally provided by Ford Motor Company because it can affect
the safety and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover, and/or serious
personal injury or death.
Make sure all tires and wheels on the vehicle are of the same size, type,
tread design, brand and load-carrying capacity. If you have questions
regarding tire replacement, see an authorized Ford or Lincoln/Mercury
dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford Motor Company recommends, you should not use
these tires for highway driving.
If you use any tire/wheel combination not recommended by Ford Motor
Company, it may adversely affect vehicle handling and could cause
steering, suspension, axle or transfer case failure.
Do not use “aftermarket lift kits” or other suspension modifications,
whether or not they are used with larger tires and wheels.
These “aftermarket lift kits” could adversely affect the vehicle’s handling
characteristics, which could lead to loss of vehicle control or rollover and
serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford Motor Company recommended pressure
even if it is less than the maximum pressure allowed for the tire.

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.
Spare tire information
Your vehicle may be equipped with a spare tire that can be used as
either a spare or a regular tire. The spare tire is not equipped with wheel
trim. The wheel trim from the original wheel/tire may be used on the
spare.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Use of such a tire
could result in damage to driveline components and an increased risk
of loss of vehicle control, vehicle rollover, personal injury or death.
Roadside Emergencies
161

•Revving the engine before turning it off may reduce fuel economy.
•Using the air conditioner or defroster may reduce fuel economy.
•You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
•Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
•Resting your foot on the brake pedal while driving may reduce fuel
economy.
•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.
Maintenance and Specifications

When replacing full size tires, never mix radial bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the
Certification Label. Make sure that all tires are the same size, speed
rating, and load-carrying capacity. Use only the tire combinations
recommended on the label. If you do not follow these precautions,
your vehicle handling may be affected which can lead to loss of vehicle
control, vehicle rollover and/or personal injury.
Make sure that all replacement tires are of the same size, type,
speed rating, load-carrying capacity and tread design (e.g., “All
Terrain”, “Touring”, etc.), as originally offered by Ford.
Do not replace your tires with “high performance” tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle, and increase the risk of loss of vehicle
control, vehicle rollover and/or personal injury.
Tires that are larger or smaller than your vehicle’s original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
The tires on your vehicle have all weather treads to provide traction in
rain and snow. However, in some climates, you may need to use snow
tires and chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used, as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
•Use only SAE Class S chains.
•Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
•Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
