Subaru 2008 IMPREZA - Manual (Page 367)

2. Calculate the available load ca-
pacity.
3. The total weight now exceeds
the capacity weight by 32 lbs (15
kg), so the cargo weight must be
reduced by 32 lbs (15 kg) or more.
NOTE
Your vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, never
tow a trailer with your vehicle.
& Determining compatibility of
tire and vehicle load capaci-
ties
The sum of four tires
’ maximum
load ratings must exceed the max-
imum loaded vehicle weight
(
“GVWR”). In addition, sum of the
maximum load ratings of two front
tires and of two rear tires must
exceed each axle
’s maximum
loaded capacity (
“GAWR”). Original
equipment tires are designed to
fulfill those conditions.
The maximum loaded vehicle
weight is referred to Gross Vehicle
Weight Rating (GVWR). And each
axle
’s maximum loaded capacity is
referred to Gross Axle Weight Rat-
ing (GAWR). The GVWR and each
axle
’s GAWR are shown on the
vehicle certification label affixed to
the driver
’s door.
The GVWR and front and rear
GAWRs are determined by not only
the maximum load rating of tires but
also loaded capacities of the vehi-
cle
’s suspension, axles and other
parts of the body.
Therefore, this means that the
vehicle cannot necessarily be
loaded up to the tire
’s maximum
load rating on the tire sidewall.
& Adverse safety conse-
quences of overloading on
handling and stopping and
on tires
Overloading could affect vehicle
handling, stopping distance, and
vehicle and tire performance in the
following ways. This could lead to
an accident and possibly result in
severe personal injury.
. Vehicle stability will deteriorate.
. Heavy and/or high-mounted
loads could increase the risk of
rollover.
. Stopping distance will increase.
. Brakes could overheat and fail.
