&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
vehiclecontrolcanleadtoanaccident. . 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 11-29 .
Replace any damaged or
unevenly 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, refer to
“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.
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 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 information about vehicle load-
ing, refer to “Loading your vehicle ”
F 8-11 .
For information about towing capa-
city and weight limits, refer to “ Trailer towing ”F 8-20 .

! Calculating total and load ca-
pacities varying seating con-
figurations
Calculate the available load capa-
city as shown in the followingexamples.
Example 1A
Vehicle capacity weight of the
vehicle is 1,157 lbs (525 kg), which
is indicated on the vehicle placard
with the statement “The combined
weight of occupants and cargo
should never exceed 525 kg or
1,157 lbs ”.
For example, if the vehicle has one occupant weighing 154 lbs (70 kg)
plus cargo weighing 882 lbs (400 kg).
1. Calculate the total weight.
2.Calculate the available load ca-
pacity by subtracting the total
weight from the vehicle capacity
weight of 1,157 lbs (525 kg).
3. The result of step 2 shows that a
further 121 lbs (55 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 55 lbs (25
kg), so the cargo weight must be
reduced by 55 lbs (25 kg) or more.
Example 2A
Vehicle capacity weight of the vehicle is 1,157 lbs (525 kg), which
is indicated on the vehicle placard
with the statement
“The combined
weight of occupants and cargo
should never exceed 525 kg or
1,157 lbs ”.
For example, the vehicle has one
occupant weighing 165 lbs (75 kg)
plus cargo weighing 705 lbs (320
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 88 lbs (40 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 105 lbs (48
kg), so the cargo weight must be
reduced by 105 lbs (48 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 eachaxle
’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, 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
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-
able cargo and luggage load capa-
city is 650 lbs. (1,400 750 (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-
