!Maximum load rating
The load rating at the maximum
permissible weight load for this tire.
For example, “MAX. LOAD 580 kg
(1279 LBS) @ 300 kPa (44 PSI)
MAX. PRESS. ”
WARNING
Maximum load rating applies
only to the tire, not to the
vehicle. Putting a load rated
tire on any vehicle does not
mean the vehicle can be
loaded up to the tire ’s rated
load.
! Construction type
Applicable construction of this tire.
For example, “TUBELESS STEEL
BELTED RADIAL ”
! Construction
The generic name of each cord
material used in the plies (both
sidewall and tread area) of this tire.
For example, “PLIES: TREAD 2 STEEL + 2 POLYESTER SIDE-
WALL 2 POLYESTER
”
! Uniform Tire Quality Grading (UTQG)
For details, refer to “Uniform tire
quality grading standards ”F 13-14 .
& Recommended tire inflation pressure
! Recommended cold tire infla-
tion pressure
For recommended cold tire inflation
pressure for your vehicle ’s tires,
refer to “Tires ”F 12-10 .
! Vehicle placard
The vehicle placard is affixed to the driver ’s side B-pillar.
Example:
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 in-

crease in temperature could cause
tread separation, and failure of the
tire(s). Possible resulting loss of
vehicle control could lead to anaccident. !Measuring and adjusting air
pressure to achieve proper in-
flation
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 out-
doors before driving the vehicle.
When a tire becomes warm, the 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. &

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
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 anaccident. . To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the
tires every 7,500 miles (12,000 km).
For information about the tire rota-
tion order, refer to “Tire rotation ”
F 11-36 .

Replace any damaged or un-
evenly worn tires at the time of
rotation. After tire rotation, adjust
the tire pressures and make sure
the wheel nuts are correctly tigh-
tened. For information about the
tightening torque and tightening
sequence for the wheel nuts, referto “Flat tires ”F 9-6 .
& 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 followingmethod.
Cargo capacity = Load limit
(total
weight of occupants + total weight
of optional equipment + tongue
load of a trailer (if applicable))
For information about vehicle load-
ing, refer to “Loading your vehicle ”
F 8-12 .
For information about towing capa-
city and weight limits, refer to“ Trailer towing ”F 8-18 .
! 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 (300kg).

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.
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 900 lbs (408 kg), which
is indicated on the vehicle placard

13-12Consumer information and Reporting safety defects
with the statement “The combined
weight of occupants and cargo
should never exceed 408 kg or
900 lbs ”.
For example, the vehicle has one
occupant weighing 165 lbs (75 kg)
plus cargo weighing 375 lbs (170
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 162 lbs (73 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 same
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 asfollows. 1.
Calculate the total weight.
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. & 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 eachaxle ’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. .
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 Limit
1. Locate the statement “The com-
bined weight of occupants and
cargo should never exceed XXXpounds ”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 kilograms or XXX pounds. 4. 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-
