Consumer information and Reporting safety defects/Tire information
& 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 ’ streadwear
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
vehiclecontrolcanleadtoan
accident. .
Replace any damaged or un-
evenly worn tires at the time of
rotation. For information about the
tire rotation order, refer to “ Tire
rotation ” F 11-36 .
After tire rotation,
adjust the tire pressures and make
sure the wheel nuts are correctly
tightened. For information about the tightening torque and tighten-
ing sequence for the wheel nuts,
refer to “ Flat tires ” F 9-4 .
& 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.
Thevehicleplacardalsoshows
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 roof rack or bike carrier, etc.
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 load-
ing, refer to “ Loading your vehicle ”
F 8-10 .

! 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
vehicle is 900 lbs (408 kg), which
is indicated on the vehicle placard
with the statement “ The combined
weight of occupants and cargo
should never exceed 900 lbs or
408 kg ” .
For example, if the vehicle has one occupant weighing 154 lbs (70 kg)
plus cargo weighing 662 lbs (300
kg). 1.
Calculate the total weight.
2.
Calculate the available load ca-
pacity by subtracting the total
weight from the vehicle capacity
weight of 900 lbs (408 kg).
3.
The result of step 2 shows that a
further 84 lbs (38 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 calcula-
tions are as follows.
1.
Calculate the total weight.Consumer information and Reporting safety defects/Tire information

2.
Calculate the available load ca-
pacity.
3.
The total weight now exceeds
the capacity weight by 92 lbs (42
kg), so the cargo weight must be
reduced by 92 lbs (42 kg) or more.
Example 2A
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, the vehicle has one
occupant weighing 165 lbs (75 kg)
plus cargo weighing 265 lbs (120
kg). In addition, the vehicle is fitted
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)).
1.
Calculate the total weight. 2.
Calculate the available load ca-
pacity.
3.
The result of step 2 shows that a
further 172 lbs (78 kg) of cargo can
be carried.
Example 2B
For example, if a person weighing
143 lbs (65 kg) and a child weighing
40 lbs (18 kg) now enter the same13-12

vehicle (bringing the number of
occupants to three), and a child
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 ca-
pacity. 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 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 ’ smaximum
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.Consumer information and Reporting safety defects/Tire information

.
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 body parts 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 Limit1.
Locate the statement “ The com-
bined 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 exam-
ple, if the “ XXX ” amount equals
1400 lbs. and there will be five 150
lb passengers in your vehicle, the
amount of available cargo and
luggage load capacity is 650 lbs.
(1400 − 750 (5 6 150) = 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 ve-
hicle. 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 maxi-
mum section width. For example:
Treadwear 200 Traction AA Tem-
perature 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-13-14

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 accel-
eration, cornering, hydroplan-
ing, or peak traction charac-
teristics.
& 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-
dards 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 ex-
cessive loading, either sepa-
rately or in combination, can
cause heat buildup and possi-
ble tire failure.Consumer information and Reporting safety defects/Uniform tire quality grading standards
