2008 FORD ECONOLINE change wheel

Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
WARNING:Under-inflation is the most common cause of tire
failures and may result in severe tire cracking, tread separation
orblowout, with unexpected loss of vehicle control and increased risk
of injury. Under-inflation increases sidewall flexing and rolling
resistance, resulting in heat buildup and internal damage to the tire. It
also may result in unnecessary tire stress, irregular wear, loss of
vehicle control and accidents. A tire can lose up to half of its air
pressure and not appear to be flat!
Always inflate your tires to the Ford recommended inflation pressure
even if it is less than the maximum inflation pressure information found
on the tire. The Ford recommended tire inflation pressure is found on
the Safety Compliance Certification Label or Tire Label which is located
on the B-Pillar or the edge of the driver’s door. Failure to follow the tire
pressure recommendations can cause uneven treadwear patterns and
adversely affect the way your vehicle handles.
Maximum Permissible Inflation Pressureis the tire manufacturer’s
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer’s recommended cold inflation pressure
which can be found on the Safety Compliance Certification Label or Tire
Label which is located on the B-Pillar or the edge of the driver’s door.
The cold inflation pressure should never be set lower than the
recommended pressure on the Safety Compliance Certification Label or
Tire Label.
When weather temperature changes occur, tire inflation pressures also
change. A 10° F (6° C) temperature drop can cause a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures
frequently and adjust them to the proper pressure which can be found
on the Safety Compliance Certification Label or Tire Label.

Information on “P” type tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
1.P:Indicates a tire, designated by
the Tire and Rim Association
(T&RA), that may be used for
service on cars, SUVs, minivans and
light trucks.
Note:If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire
Manufacturing Association).
2.215:Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
3.65:Indicates the aspect ratio which gives the tire’s ratio of height to
width.
4.R:Indicates a “radial” type tire.
5.15:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
6.95:Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
Owner’s Guide.If not, contact a local tire dealer.
Note:You may not find this information on all tires because it is not
required by federal law.
7.H:Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.

Information on “T” type tires
“T” type tires have some additional
information beyond those of “P”
type tires; these differences are
described below:
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades do
not apply to this type of tire.
1.T:Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service on
cars, SUVs, minivans and light
trucks.
2.145:Indicates the nominal width
of the tire in millimeters from sidewall edge to sidewall edge. In general,
the larger the number, the wider the tire.
3.80:Indicates the aspect ratio which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
4.D:Indicates a “diagonal” type tire.
R:Indicates a “radial” type tire.
5.16:Indicates the wheel or rim diameter in inches. If you change your
wheel size, you will have to purchase new tires to match the new wheel
diameter.
Location of the tire label
You will find a Tire Label containing tire inflation pressure by tire size
and other important information located on the B-Pillar or the edge of
the driver’s door. Refer to the payload description and graphic in the

Maximum trailer weight for all cutaway (E-350 and E-450) vehicles
must be calculated by subtracting the weight of the vehicle (including
incomplete vehicle weight and payload which includes second unit
body weight, cargo and passengers) from the GCW. Otherwise,
maximum trailer weight is 10,000 lb. (4536 kg).
For high altitude operation reduce GCWR by 2% per 1,000 ft.
(300 meters) elevation.
To determine the maximum trailer weight designed for your particular
vehicle as equipped, follow the sectionVehicle loadingearlier in this
chapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Distribute the load so that only 10–15% of the total is on the tongue. Tie
down the load so that it does not shift and change the weight on the
hitch.
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.
Do not exceed trailer weight of 5,000 lb (2,268 kg) when towing with
bumper only.

Replace the rear axle lubricant any time the axle has been submerged in
water. Rear axle lubricant quantities are not to be checked or changed
unless a leak is suspected or repair required.
RECREATIONAL TOWING
Follow these guidelines if you have a need for recreational (RV) towing.
An example of recreational towing would be towing your vehicle behind
a motorhome. These guidelines are designed to ensure that your
transmission is not damaged.
All vehicles:Do not tow your vehicle with any wheels on the ground, as
vehicle or transmission damage may occur. It is recommended to tow
your vehicle with all four (4) wheels off the ground such as when using a
car-hauling trailer. Otherwise, no recreational towing is permitted.
In case of a roadside emergency with a disabled vehicle, seeWrecker
towingin theRoadside Emergencieschapter.

If a system fault is detected, the traction control active light will
illuminate, the Traction Control™ button will not turn the system on or
off and your vehicle should be serviced by an authorized dealer.
ADVANCETRACWITH ROLL STABILITY CONTROL™ (RSC)
STABILITY ENHANCEMENT SYSTEM (IF EQUIPPED)
The AdvanceTrac
with RSC system provides stability and traction
enhancement for certain driving situations when driver assistance is
needed. It helps your vehicle maintain traction, when driving on slippery
and/or hilly road surfaces, by detecting and controlling wheel spin.
Excessive wheel spin is controlled by momentarily reducing engine
power and rapidly applying the anti-lock brakes. The system is a driver
aid which makes your vehicle easier to handle primarily on snow and
ice-covered roads.
If your vehicle should become stuck in deep snow or mud, try switching
the AdvanceTrac
with RSC system off by pressing the AdvanceTrac

with RSC button. This will allow your tires to “dig” for traction.
Remember to switch the AdvanceTrac
with RSC system back on once
the vehicle is no longer stuck.
If the AdvanceTrac
with RSC system is activated excessively in a short
period of time, the brake portion of the system will shut down to allow
the brakes to cool down. A limited AdvanceTrac
with RSC function
using only engine power reduction will still help control the wheels from
over-spinning. When the brakes have cooled down, the system will again
function normally. Anti-lock braking is not affected by this condition and
will function normally during the cool-down period.
The AdvanceTrac
with RSC system enhances your vehicle’s stability
during maneuvers that require all available tire traction, like in
wet/snowy/icy road conditions and/or when performing emergency
maneuvers. In an emergency lane-change, the driver will experience
better overall vehicle traction, and have better control of the vehicle.
The AdvanceTrac
with RSC system helps the driver maintain steering
control if the vehicle begins to slide excessively left or right or spin out.
AdvanceTrac
with RSC will attempt to correct the sliding motion by
applying brake force at individual tires and, if necessary, by reducing
engine power.

WARNING:Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or death. The occurrence of a AdvanceTrac
with RSC
event is an indication that at least some of the tires have exceeded
their ability to grip the road; this may lead to an increased risk of loss
of vehicle control, vehicle rollover, personal injury and death. Operating
your vehicle with AdvanceTrac
with RSC system disabled may
severely reduce your ability to control your vehicle. If you experience a
severe road event or any loss of vehicle control, SLOW DOWN.
Driving conditions which may activate AdvanceTrac
with RSC system
include:
•Taking a turn too fast.
•Maneuvering quickly to avoid an accident, pedestrian or obstacle.
•Hitting a patch of ice.
•Changing lanes on a snow-rutted road.
•Entering a snow-free road from a snow-covered side street, or vice
versa.
•Entering a paved road from a gravel road, or vice versa.
•Hitting a curb while turning.
•Driving on slick surfaces.
•Cornering while towing a heavily loaded trailer (refer toTrailer
towingin theTires, Wheels and Loadingchapter.)
The RSC system works in conjunction with the AdvanceTrac
system to
further enhance the vehicle’s overall stability during aggressive
maneuvers. The system helps maintain roll stability of the vehicle during
aggressive maneuvers by applying brake force to one or more wheels.
Driving conditions that may activate Roll Stability Control include:
•Emergency lane-change
•Taking a turn too fast
•Quick maneuvering to avoid an accident, pedestrian or obstacle
The AdvanceTrac
with RSC system automatically turns on when the
engine is started. However, the system does not function when the
vehicle is traveling in R (Reverse). In R (Reverse), ABS and the traction
enhancement feature will continue to function.

Some drivers may notice a slight movement of the brake pedal when the
AdvanceTrac
with RSC performs a system self-check. During
AdvanceTrac
with RSC operation you may experience the following:
•A rumble or grinding noise
•A slight deceleration of the vehicle
•Steering feedback
•The AdvanceTrac
with RSC indicator light will flash
•If your foot is on the brake pedal, you will feel a vibration in the
pedal.
All these conditions are normal during AdvanceTrac
with RSC
operation.
Do not alter or modify your vehicle’s suspension, steering or
tires; the resulting changes to the vehicle’s handling can
adversely affect the AdvanceTrac
with RSC system. Also, do not
install a stereo loudspeaker. The speaker vibrations can adversely
affect the AdvanceTrac
with RSC sensors.
STEERING
To help prevent damage to the power steering system:
•Never hold the steering wheel at its furthest turning points (until it
stops) for more than a few seconds when the engine is running.
•Do not operate the vehicle with a low power steering pump fluid level
(If the fluid level is below the FULL COLD range on the dipstick).
•Some noise is normal during operation. If the noise is excessive, check
for low power steering pump fluid level before seeking service by your
authorized dealer.
•Heavy or uneven steering efforts may be caused by low power steering
pump fluid level. Check for low power steering pump fluid level before
seeking service by your authorized dealer.
•Do not fill the power steering pump reservoir above the FULL COLD
range on the dipstick, as this may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
