Load rating (code )
means the maximum load that a
tire is ra ted to carry for a given in
flation pressure. You may not find
this info rmatio n on all tires be
cause it is not required by law .
Maximum load rating
means the load rating for a tire at
the maximum permissible infla

Maximum loaded vehicle
weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Ma ximum (permissible )
inflation pressure
means the maximum cold infla
tion pressure to which a tire may be inflated . A lso called "maxi
mum inflation pressure."
Normal occupant weight
means 150 lbs (68 kg) times the
number of occupants seated in
the vehicle up to the total seating
capacity of your vehicle.

Occupant distribution
means distribution of occupants
in a vehicle.
Outer diameter
means the overall diameter of an
inflated new tire.
Overall width
means the linear distance be

Ply
means a layer of rubber-coated
parallel cords.
Production options weight
means the combined weight of
those installed regular production options weighing over 5 lbs

Tread separation
means pulling away of the tread
from the tire carcass .
Treadwear indicators (TWI)
means the projections within the
principal grooves designed to give
a visual indication of the degrees
of wear of the tread . See

Uniform Tire Quality Grading
is a tire information system devel
oped by the United States Nation
al Highway Traffic Safety Admin
istration (NHTSA) that is designed
to help buyers make relat ive com
parisons among tires. The UTQG
is not a safety rat ing and not a
guarantee that a tire will last for
a prescr ibed number of miles
( kilometers) or perform in acer
tain way . It simply gives tire buy
ers additional information to
combine with other considera
tions, such as price, brand loyalty
and dealer recommendations . Un
der UTQG, t ires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera
ture resistance . The UTQG infor -

U.S. DOT Tire Identification
Number (TIN )
This is the tire's "serial number".
It begins with the letters
"DOT"
and indicates that the tire meets
all federal standards. The next
two numbers or letters indicate
the plant where it was manufac tured, and the last four numbers
represent the week and year of
manufacture . Fo r example,
DOT ... 2217 ...
means that the tire was produced
in the 22nd week of 2017. The
other numbers are marketing co
des that may or may not be used by the tire manufacturer. This in
formation is used to contact con
sumers if a tire defect requires a recall.
Veh icle capac ity weight
means the rated cargo and lug
gage load plus 150 lbs (68 kg)

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to loss of vehicle control, but can al
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout

Your safety and that of your pas
sengers also depends on making
sure that load limits are not ex
ceeded. Vehicle load includes ev
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi
cle's
Gross Vehicle Weight Rat
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi
mum load includes the number
of .,.

passengers that the vehicle is in
tended to carry ("seating capaci
ty") with an assumed weight of
150 lbs. (68 kg) for each passen
ger at a designated seating posi
tion and the total weight of any luggage in the vehicle.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle is limited.
The more passengers in the vehi
cle or passengers who are heavier
than the standard weights as sumed mean that less weight can
be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compli
ance sticker label located on the
driver's side B-pillar.
A WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per
sonal injury, and even death .
Wheels
-Carrying more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and
increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance.
- Tires on a vehicle that has
been overloaded can fail sud
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-A lways make sure that the to
tal load being transported
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
Determining correct load
limit
Use the example below to calcu
late the total weight of the pas
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.

Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
c:> page 254 , fig. 189 .
2. Determine the combined
weight of the driver and pas
sengers that will be riding in
your vehicle.
3 . Subtract the combined weight
of the driver and passengers
from
"XXX " kilograms or "XXX"
pounds shown on the sticker
c:> page 254 , fig. 189 .
4. The resulting figure equals the
available amount of cargo and
luggage load capacity. For ex
ample, if the
" XXX" amount
equals 1400 lbs and there will be five 150 lbs passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lbs
(1400-750 (5
X 150) = 650 lbs)
5 . Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex
ceed the available cargo and
258
luggage load capa city cal culat
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be tran sferred to your ve
hicle. Con sult thi s manual to
determine how this reduces
the available cargo and lug
gage load capacity of your vehi
c le .
~check the tire sidewall
(c:> page 245 , fig. 187) to deter
mine the designated load rating
for a spe cifi c tire.

@ Note
-Be aware of t he fo llow ing poin ts befo re lift
in g th e vehicle:
-The vehicle should never be lifted or
jacked up from underneath the engine oil
pan, the transmission housing, the front
or rear axle or the body side members.
This could lead to serious damage.
- To avoid damage to the underbody or
chassis frame, a rubber pad must be in
serted between the floor jack and the lift
points.
- Before driving over a workshop hoist,
check that the vehicle weight does not
exceed the permissible lifting capacity of
the hoist.
- Before driving over a workshop hoist , en
sure that there is sufficient clearance be
tween the hoist and low parts of the ve
hicle.
