Tire and Loading Information Label
A vehicle speci c Tire and Loading Information
label is attached to the center pillar (B-pillar).
With the driver’s door open, you will nd the
label attached below the door lock post (striker).
The tire and loading information label shows
the number of occupant seating positions (A),
and the maximum vehicle capacity weight (B)
in kilograms and pounds.The Tire and Loading Information label also shows
the size of the original equipment tires (C) and
the recommended cold tire in ation pressures (D).
For more information on tires and in ation see
Tires on page 5-60andInflation - Tire Pressure
on page 5-67.
There is also important loading information on
the vehicle Certi cation/Tire label. It tells you the
Gross Vehicle Weight Rating (GVWR) and the
Gross Axle Weight Rating (GAWR) for the
front and rear axle. See “Certi cation/Tire Label”
later in this section.
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.
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.

Your vehicle has an electronically controlled air
suspension system that automatically keeps your
vehicle level as you load and unload your vehicle.
SeeElectronically Controlled Air Suspension
System on page 4-28for additional information.
Certi cation/Tire Label
A vehicle speci c Certi cation/Tire label is found
on the rear edge of the driver’s door. The label
shows the size of your vehicle’s original tires and
the in ation pressures needed to obtain the gross
weight capacity of your vehicle.This is called Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight of the
vehicle, all occupants, fuel, cargo, and trailer
tongue weight, if pulling a trailer.
The Certi cation/Tire label also tells you the
maximum weights for the front and rear axles,
called Gross Axle Weight Rating (GAWR).
To nd out the actual loads on your front and
rear axles, you need to go to a weigh station
and weigh your vehicle. Your dealer can help
you with this. Be sure to spread out your
load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle,
or the GAWR for either the front or rear axle.
And, if you do have a heavy load, you should
spread it out.
Similar appearing vehicles may have different
GVWRs and capacity weights. Please note
your vehicle’s Certi cation/Tire label or consult
your dealer for additional details.

CAUTION: (Continued)
Underin ated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked when
your tires are cold. SeeInflation - Tire
Pressure on page 5-67.
Overin ated tires are more likely to be
cut, punctured, or broken by a sudden
impact — such as when you hit a
pothole. Keep tires at the
recommended pressure.
Worn, old tires can cause accidents.
If your tread is badly worn, or if
your tires have been damaged,
replace them.
SeeHigh-Speed Operation on page 5-68
for in ation pressure adjustment for high
speed driving.
Low-Pro le Performance Tire
If your vehicle has P255/50R20 size tires, they are
classi ed as low-pro le performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. You may also notice more
road noise with low-pro le performance tires and
that they tend to wear faster.
Notice:If your vehicle has low-pro le tires,
they are more susceptible to damage from road
hazards or curb impact than standard pro le
tires. Tire and/or wheel assembly damage can
occur when coming into contact with road
hazards like, potholes, or sharp edged objects,
or when sliding into a curb. Your vehicle
warranty does not cover this type of damage.
Keep tires set to the correct in ation pressure
and, when possible avoid contact with curbs,
potholes, and other road hazards.

(G) Maximum Cold In ation Load Limit:Maximum load that can be carried and the
maximum pressure needed to support that load.

andLoading Your Vehicle on page 4-22.
Tire Size
The following examples show the different parts of
a tire size.
(A) Passenger (P-Metric) Tire
:The United States
version of a metric tire sizing system. The letter P
as the rst character in the tire size means a
passenger vehicle tire engineered to standards
set by the U.S. Tire and Rim Association.(B) Tire Width
:The three-digit number indicates
the tire section width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio
:A two-digit number that
indicates the tire height-to-width measurements.
For example, if the tire size aspect ratio is 75, as
shown in item C of the passenger (P-Metric) tire
illustration, it would mean that the tire’s sidewall is
75 percent as high as it is wide.
(D) Construction Code
:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D
means diagonal or bias ply construction; and the
letter B means belted-bias ply construction.
(E) Rim Diameter
:Diameter of the wheel in
inches.
(F) Service Description
:The service description
indicates the load range and speed rating of a
tire. The load index can range from 1 to 279.
Speed ratings range from A to Z.Passenger (P-Metric) Tire

In ation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under-in ation or over-in ation is all right.
It is not. If your tires do not have enough air
(under-in ation), you can get the following:
Too much exing
Too much heat
Tire overloading
Premature or irregular wear
Poor handling
Reduced fuel economy
If your tires have too much air (over-in ation),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazardsA vehicle speci c Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct in ation pressures for your tires when they
are cold. The recommended cold tire in ation
pressure, shown on the label, is the minimum
amount of air pressure needed to support your
vehicle’s maximum load carrying capacity.
For additional information regarding how much
weight your vehicle can carry, and an example of
the Tire and Loading Information label, seeLoading
Your Vehicle on page 4-22. How you load your
vehicle affects vehicle handling and ride comfort.
Never load your vehicle with more weight than it
was designed to carry.
When to Check
Check your tires once a month or more.
Do not forget to check the pressure of the spare
tire. SeeSpare Tire on page 5-101for additional
information.
