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.
