2003 FORD WINDSTAR tire size

•If your low tire warning light is on, refer toLow tire warningin the
Maintenance and specificationschapter.
The use of tire sealants is not recommended and may
compromise the integrity of your tires. The use of tire sealants
may also affect your tire pressure monitoring system (if equipped).
Temporary spare tire information
Your vehicle may have a temporary spare tire. The temporary spare tire
for your vehicle is labeled as such. It is smaller than a regular tire and is
designed for emergency use only. Replace this tire with a full-size tire as
soon as possible.
Note:The Low Tire Warning system
will detect the temporary spare tire
and illuminate the low tire warning
light until the spare tire is replaced
with a proper full-size tire.
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:
•use more than one temporary spare tire at a time
•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 tire chains
•drive through an automatic car wash, because of the vehicle’s reduced
ground clearance
•try to repair the temporary spare tire or remove it from its wheel
•use the wheel for any other type of vehicle
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
208

•Two or more under inflated tires.
•Sudden loss of tire pressure.
•Vehicle speeds less than 30 km/h (20 mph), greater than 120 km/h
(70 mph) or driving duration less than 10 miles.
•Transporting a heavy load or towing a trailer.
•A different tire was replaced and was not the same brand, type, size,
speed rating, load carrying capacity and DOT code as the other tire on
the same axle.
•System was not reset after tire rotation, air pressure adjustment, a tire
change, wheel alignment or tire balancing.
•System was not reset after the ABS warning lamp illuminates.
The low tire warning feature can be turned off by your dealer.
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.
•Reset low tire warning system
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control.
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
them as indicated in the scheduled maintenance guide. If you notice that
the tires wear unevenly, have them checked.
Maintenance and Specifications
217

•Four tire rotation
Reset low tire warning system after rotating tires.
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
Reset low tire warning system after replacing tires.
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. If one tire needs to be replaced
sooner than the other on the same axle replace it with the same brand,
type, size, speed rating, load carrying capacity and DOT code as the
other tire. Note: tires on the same axle (front or rear) must match for
the low tire warning system to function properly. Use only the tire
combinations recommended on the label. If you do not follow these
precautions, your vehicle may not drive properly and safely.
Maintenance and Specifications
218

Make sure that all replacement tires are of the same size, type,
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.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in 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
Driving too fast for conditions creates the possibility of loss of
vehicle control. Driving at very high speeds for extended periods
of time may result in damage to vehicle components.
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:
•Do not use tire chains with 235/60R16 and P235/55R17 size tires.
•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.
•If possible, avoid fully loading your vehicle.
