&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 7,500 miles (12,000 km).
For information about the tire rota-
tion order, refer to“
Tire rotation”
F11-25.
Replace any damaged or
unevenly worn tires at the time ofrotation. 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”F9-5.
&Determining compatibility of
tire and vehicle load capaci-
tiesThe 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 eachaxle’s GAWR are shown on the
vehicle certification label located at
the bottom of driver’s side door
pillar.
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
tiresOverloading 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 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 andluggage 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.
(1400750 (56150) = 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.
Vehicle load limit–how to
determineThe 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
door 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 information about vehicle load-
ing, refer to“
Loading your vehicle”
F8-11.
&Calculating total and load
capacities varying seating
configurationsCalculate the available load capa-
city as shown in the following
examples:Example 1AVehicle capacity weight of the ve-
hicle is 900 lbs (408 kg), which isindicated 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 afurther 84 lbs (38 kg) of cargo can
be carried.
Example 1BFor 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.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 2AVehicle capacity weight of the ve-
hicle 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 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 thetrailer 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.
