The vehicle placard shows original
tire size, recommended cold tire
inflation pressure on each tire at
maximum loaded vehicle weight,
seating capacity and loading infor-
mation.
▼Adverse safety consequences
of under-inflation
Driving at high speeds with exces-
sively low tire pressures can cause
the tires to flex severely and to
rapidly become hot. A sharp
increase in temperature could
cause tread separation, and failure
of the tire(s). Possible resulting loss
of vehicle control could lead to an
accident.
▼ Measuring and adjusting air
pressure to achieve proper
inflation
Check and, if necessary, adjust the
pressure of each tire (including the
spare) at least once a month and
before any long journey. Check the
tire pressures when the tires are
cold. Use a pressure gauge to adjust the tire pressures to the
specific values. Driving even a short
distance warms up the tires and
increases the tire pressures. Also,
the tire pressures are affected by
the outside temperature. It is best to
check tire pressure outdoors before
driving the vehicle. When a tire
becomes warm, t
he air inside it
expands, causing the tire pressure
to increase. Be careful not to
mistakenly release air from a warm
tire to reduce its pressure.
■ Glossary of Tire TerminologyAccessory weight
The combined weight (in excess of
those standard items which may be
replaced) of automatic transmis-
sion, power steering, power brakes,
power windows, power seats, radio,
and heater, to the extent that these
items are available as factory-
installed equipment (whether
installed or not).
 Bead
The part of the tire that is made of
steel wires, wrapped or reinforced by ply cords and that is shaped to fit
the rim.

Bead separation
A breakdown of the bond between
components in the bead.
 Bias ply tire
A pneumatic tire in which the ply
cords that extend to the beads are
laid at alternate an gles substantially
less than 90 degrees to the
centerline of the tread.
 Carcass
The tire structure, except tread and
sidewall rubber which, when
inflated, bears the load.
 Chunking
The breaking away of pieces of the
tread or sidewall.
 Cold tire pressure
The pressure in a tire that has been
driven less than 1 mile or has been
standing for three hours or more.
 Cord
The strands forming the plies in the
tire.

Tire Care – Maintenance and
Safety PracticesCheck on a daily basis that the
tires are free from serious damage,
nails, and stones. At the same time,
check the tires for abnormal wear.
 Inspect the tire tread regularly
and replace the tires before their
tread wear indicators become
visible. When a tire’s tread wear
indicator becomes visible, the tire is
worn beyond the acceptable limit
and must be replaced immediately.
With a tire in this condition, driving
at even low speeds in wet weather
can cause the vehicle to hydro-
plane. Possible resulting loss of
vehicle control can lead to an acci-
dent.
 To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the tires
every 6,000 miles (10,000 km). For
information about tire rotation, refer
to
"Rotational Direction of Tires" 
P364.
Replace any damaged or unevenly
worn tire at the time of rotation. After
tire rotation, adjust the tire pres-

Vehicle Load Limit – How to
Determine
The load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the vehicle
placard attached to the driver’s side
B-pillar. Locate the statement “
The
combined weight of occupants and cargo
should never exceed XXX kg or XXX lbs
”
on your vehicle’s placard.
The vehicle placard also shows
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all passen-
gers and their belongings, any
cargo, any optional equipment such
as a trailer hitch, roof rack or bike
carrier, etc., and the tongue load of
a trailer. Therefore cargo capacity
can be calculated by the following
method. Cargo capacity = Load limit
− (total
weight of occupants + total weight of
optional equipment)
For information about vehicle
loading, refer to
"Loading Your Vehicle"

P297.▼
Calculating total and load
capacities varying seating
configurations
Calculate the available load
capacity as shown in the following
examples:
Example 1A Vehicle capacity weight of the
vehicle is 800 lbs (363 kg), which is
indicated on the vehicle placard with
the statement “The combined
weight of occupants and cargo
should never exceed 363 kg or 800
lbs”.
For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
CAUTION
Your vehicle is neither
designed nor intended to be
used for trailer towing. There-
fore, never tow a trailer with
your vehicle.

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.

406Suspension, 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.

Uniform Tire Quality Grading Standards
407
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.
