²GAWR (Gross Axle Weight
Rating) ÐCarrying capacity
for each axle system (front and
rear). The GAWR is specific to
each vehicle and is listed on the
Safety Compliance Certification
Label on the driver door pillar.
²GCW (Gross Combined
Weight) ÐThe GCW is the
maximum combined weight of
the towing vehicle (including
passengers and cargo) and the
loaded trailer. The GCW is
specified by the manufacturer to
indicate the combined maximum
loaded weight that the vehicle is
designed to tow.
Payload = GVWR minus Base
curb weight
To obtain the correct weights for
your vehicle, try taking your
vehicle to a shipping company or
an inspection station for trucks.
Do not use replacement tires with
lower weight capacities than the
originals because they might lower
the vehicle's GVWR and GAWR.
(Replacement tires with a higher
weight limit than the originals do
not increase the GVWR or the
GAWR limitations.)
In high altitudes, engines will lose
power at a rate of 3% power per
300 m (1000 ft) increase in
elevation. A reduction in GVW and
GCW is recommended for
maximum vehicle performance.

Replacing tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size
tires, never mix radial,
bias-belted, or bias-type tires.
Use only the tire sizes that are
listed on the tire pressure decal.
Make sure that all tires are the
same size, speed rating, and
load-carrying capacity. Use only
the tire combinations
recommended on the decal. If
you do not follow these
precautions, your vehicle may
not drive properly and safely.

Make sure that all
replacement tires are of
the same size, type, load-carrying
capacity and tread design (e.g.,
ªAll Terrainº, etc.), as originally
offered by Ford.
Do not replace your tires
with ªhigh performanceª
tires or larger size tires.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Refer to the Safety Compliance
Certification label to determine the
specific size tire and wheel Ford
Motor Company recommends for
use on this vehicle.
When purchasing replacement tires
for your vehicle, consult your
dealer or qualified service
technician to ensure that the
correct tire types are used.
