restraint system weighing 11 lbs (5
kg) is installed in the vehicle for the
child to use, the calculations are as
follows:
1. Calculate the total weight.
2. Calculate the available load
capacity.3. The total weight now exceeds
the capacity weight by 22 lbs (10
kg), so the cargo weight must be
reduced by 22 lbs (10 kg) or more.
■
Determining Compatibility of
Tire and Vehicle Load Capac-
itiesThe sum of four tires’ maximum
load ratings must exceed the
maximum 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 (“GVWR”). 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
Rating (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
vehicle’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 TiresOverloading could affect vehicle
handling, stopping distance, vehicle
and tire as shown in the following.
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.

406Suspension, bearings, axles and
other parts of the body could break
or experience accelerated wear that
will shorten vehicle life.
Tires could fail.
Tread separation could occur.
Tire could separate from its rim.■ Steps for Determining
Correct Load Limit1. Locate the statement “The
combined weight of occupants and
cargo should never exceed XXX kg
or XXX lbs.” on your vehicle’s
placard.
2. Determine the combined weight
of the driver and passengers that
will be riding in your vehicle.
3. Subtract the combined weight of
the driver and passengers from
XXX kg or XXX lbs.
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For
example, if the “
XXX
” amount equals
1,400 lbs (635 kg) and there will be
five 150 lbs (68 kg) passengers in your vehicle, the amount of avail-
able cargo and luggage load
capacity is 650 lbs (1,400
− 750 (5 ×
150) = 650 lbs).
5. Determine the combined weight
of luggage and cargo being loaded
on the vehicle. That weight may not
safely exceed the available cargo
and luggage load capacity calcu-
lated in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer will be
transferred to your vehicle. Consult
this manual to determine how this
reduces the available cargo and
luggage load capacity of your
vehicle.
13-3. Uniform Tire Quality Grading StandardsThis information i ndicates the rela-
tive performance of passenger car
tires in the area of treadwear, trac-
tion, and temperature resistance.
This is to aid the consumer in
making an informed choice in the
purchase of tires.
Quality grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
TREADWEAR 200 TRACTION AA
TEMPERATURE A
The quality grades apply to new
pneumatic tires for use on
passenger cars. However, they do
not apply to deep tread, winter type
snow tires, space-saver or tempo-
rary use spare tires, tires with
nominal rim diameters of 12 inches
or less, or to some limited produc-
tion tires.

Consumer Information and Reporting Safety Defects13
All passenger car tires must
conform to Federal Safety Require-
ments in addition to these grades.■TREADWEARThe treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under
controlled conditions on a specified
government test course.
For example, a tire graded 150
would wear one and one-half (1-1/2)
times as well on the government
course as a tire graded 100. The
relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.■TRACTION AA, A, B, CThe traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on specified government test surfaces
of asphalt and concrete. A tire
marked C may have poor traction
performance.
■
TEMPERATURE A, B, CThe temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor labora-
tory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire failure. The
grade C corresponds to a level of
performance which all passenger car tires must meet under the
Federal Motor Vehicle Safety Stan-
dard No. 109. Grades B and A
represent higher levels of perfor-
mance on the laboratory test wheel
than the minimum required by law.
WARNING
The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteris-
tics.
WARNING
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
buildup and possible tire fail-
ure.
