maximum loaded vehicle weight,
seating capacity and loading infor-
mation.

Adverse safety conse-
quences 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 in-
crease 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, the air inside it
expands, causing the tire pressure
to increase. Be careful not to mis-
takenly release air from a warm tire
to reduce its pressure.

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 visi-
ble. When a tire’s tread wear in-
dicator 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
accident.

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).
Rotating the tires involves switching
the front and rear tires on the right-
hand side of the vehicle and simi-
larly switching the front and rear
tires on the left-hand side of the
vehicle. (Each tire must be kept on
its original side of the vehicle.)
Replace any damaged or unevenly
worn tire at the time of rotation. After
tire rotation, adjust the tire pres-
sures and make sure the wheel nuts
are correctly tightened. For informa-
tion about the tightening torque and
tightening sequence for the wheel
nuts, refer to “

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 pas-
sengers 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 + tongue load
of a trailer (if applicable))

For towing capacity information and
weight limits, refer to “

Trailer Towing

Calculating total and load ca-
pacities varying seating con-
figurations

Calculate the available load capa-
city as shown in the following
examples:

Example 1A

Vehicle capacity weight of the ve-
hicle 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”.

Tire Information

584

(587,1)

For example, if the vehicle has one
occupant weighing 154 lbs (70 kg)
plus cargo weighing 551 lbs (250
kg).

Calculate the total weight.

Calculate the available load ca-

pacity by subtracting the total
weight from the vehicle capacity
weight of 800 lbs (363 kg).

The result of step 2 shows that a

further 95 lbs (43 kg) of cargo can
be carried.

Example 1B

For example, if a person weighing
176 lbs (80 kg) now enters the same
vehicle (bringing the number of
occupants to two), the calculations
are as follows:

Calculate the total weight.

Calculate the available load ca-

pacity.

The total weight now exceeds

the capacity weight by 81 lbs (37
kg), so the cargo weight must be
reduced by 81 lbs (37 kg) or more.

For example, the vehicle has one
occupant weighing 165 lbs (75 kg)
plus cargo weighing 265 lbs (120

with a trailer hitch weighing 22 lbs
(10 kg), to which is attached a trailer
weighing 1,764 lbs (800 kg). 10% of
the trailer weight is applied to the
trailer tongue (i.e. Tongue load =

176 lbs (80 kg)).

Calculate the total weight.

Determining Compatibility of
Tire and Vehicle Load Capa-
cities

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, 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.

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 Cor-
rect Load Limit

Locate the statement “The com-

bined weight of occupants and
cargo should never exceed XXX
kg or XXX lbs.” on your vehicle’s
placard.

Determine the combined weight

of the driver and passengers that
will be riding in your vehicle.

Subtract the combined weight of

the driver and passengers from
XXX kg or XXX lbs.

The resulting figure equals the

available amount of cargo and
luggage load capacity. For exam-
ple, 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 capa-

city is 650 lbs (1,400 − 750 (5

150) = 650 lbs).

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.

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 ve-
hicle.

13-3. Uniform Tire Quality
Grading Standards

This information indicates the rela-
tive performance of passenger car
tires in the area of treadwear,
traction, and temperature resis-
tance. 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 be-
tween 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 passen-
ger cars. However, they do not
apply to deep tread, winter type
snow tires, space-saver or tempor-
ary use spare tires, tires with
nominal rim diameters of 12 inches
or less, or to some limited produc-
tion tires.

All passenger car tires must con-

Uniform Tire Quality Grading Standards

588

(591,1)

form to Federal Safety Require-
ments in addition to these grades.

TREADWEAR

The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under con-
trolled 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 govern-
ment 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, C

The 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 spe-

cified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor-
mance.

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.

TEMPERATURE A, B, C

The 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 con-
ditions 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 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
failure.
