Tire Terminology And Definitions
TermDefinition
B-Pillar The vehicle B-Pillar is the structural member of the body located
behind the front door.
Cold Tire Inflation Pressure Cold tire inflation pressure is defined as the tire pressure after
the vehicle has not been driven for at least three hours, or driven
less than 1 mile (1.6 km) after sitting for a minimum of three
hours. Inflation pressure is measured in units of PSI (pounds per
square inch) or kPa (kilopascals).
Maximum Inflation Pressure The maximum inflation pressure is the maximum permissible
cold tire inflation pressure for this tire. The maximum inflation
pressure is molded into the sidewall.
Recommended Cold Tire Inflation Pressure Vehicle manufacturer’s recommended cold tire inflation pressure
as shown on the tire placard.
Tire Placard A label permanently attached to the vehicle describing the vehi-
cle’s loading capacity, the original equipment tire sizes and the
recommended cold tire inflation pressures.

Tire Loading And Tire Pressure
Tire And Loading Information Placard Location
NOTE:The proper cold tire inflation pressure is listed
on the driver ’s side B-Pillar or the rear edge of the
driver’s side door.
Check the inflation pressure of each tire, including the
spare tire (if equipped), at least monthly and inflate to
the recommended pressure for your vehicle.
WARNING!
• Overloading of your tires is dangerous. Overload-
ing can cause tire failure, affect vehicle handling,
and increase your stopping distance. Use tires of
the recommended load capacity for your vehicle.
Never overload them.
• Improperly inflated tires are dangerous and can
cause collisions. Under-inflation increases tire
flexing and can result in over-heating and tire
failure. Over-inflation reduces a tire’s ability to

WARNING!(Continued)
cushion shock. Objects on the road and chuck
holes can cause damage that results in tire failure.
Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
Over-inflated or under-inflated tires can affect
vehicle handling and can fail suddenly, resulting
in loss of vehicle control. Always drive with each
tire inflated to the recommended cold tire infla-
tion pressure.
Tire And Loading Information Placard
This placard tells you important information about the:
1. Number of people that can be carried in the vehicle.
2. Total weight your vehicle can carry.
3. Tire size designed for your vehicle.
4. Cold tire inflation pressures for the front, rear, and
spare tires.
Loading
The vehicle maximum load on the tire must not exceed
the load carrying capacity of the tire on your vehicle.
You will not exceed the tire’s load carrying capacity if
you adhere to the loading conditions, tire size, and cold
tire inflation pressures specified on the Tire and Load-
ing Information placard in “Vehicle Loading” in the
“Starting And Operating” section of this manual.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and
rear axles must not be exceeded. For further informa-
tion on GAWRs, vehicle loading, and trailer towing,
refer to “Vehicle Loading” in the “Starting And Oper-
ating” section of this manual.

STARTING AND OPERATING 169

To determine the maximum loading conditions of your
vehicle, locate the statement “The combined weight of
occupants and cargo should never exceed XXX kg or
XXX lbs” on the Tire and Loading Information placard.
The combined weight of occupants, cargo/luggage and
trailer tongue weight (if applicable) should never ex-
ceed the weight referenced here.
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.
(4) The resulting figure equals the available amount
of cargo and luggage load capacity. For example, if
“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.
(1400-750 (5x150) = 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 calculated 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
vehicle.
Metric Example For Load Limit
For example, if “XXX” amount equals 635 kg and there
will be five 68 kg passengers in your vehicle, the
amount of available cargo and luggage load capacity is
295 kg (635-340 (5x68) = 295 kg) as shown in step 4.
170 STARTING AND OPERATING

NOTE:
•If your vehicle will be towing a trailer, load from
your trailer will be transferred to your vehicle. The
following table shows examples on how to calculate
total load, cargo/luggage, and towing capacities of
your vehicle with varying seating configurations and
number and size of occupants. This table is for
illustration purposes only and may not be accurate
for the seating and load carry capacity of your
vehicle. •
For the following example, the combined weight of
occupants and cargo should never exceed 865 lbs
(392 kg).

WARNING!
Overloading of your tires is dangerous. Overload-
ing can cause tire failure, affect vehicle handling,
and increase your stopping distance. Use tires of the
recommended load capacity for your vehicle. Never
overload them.
172 STARTING AND OPERATING

Example: If garage temperature = 68°F (20°C) and the
outside temperature = 32°F (0°C) then the cold tire
inflation pressure should be increased by 3 psi (21 kPa),
which equals 1 psi (7 kPa) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6 psi (13 to 40 kPa)
during operation. DO NOT reduce this normal pressure
build up or your tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe speeds and
within posted speed limits. Where speed limits or condi-
tions are such that the vehicle can be driven at high
speeds, maintaining correct tire inflation pressure is very
important. Increased tire pressure and reduced vehicle
loading may be required for high-speed vehicle opera-
tion. Refer to your authorized tire dealer or original
equipment vehicle dealer for recommended safe operat-
ing speeds, loading and cold tire inflation pressures.
WARNING!
High speed driving with your vehicle under maxi-
mum load is dangerous. The added strain on your
tires could cause them to fail. You could have a
serious collision. Do not drive a vehicle loaded to the
maximum capacity at continuous speeds above
75 mph (120 km/h).
Radial Ply Tires
WARNING!
Combining radial ply tires with other types of tires
on your vehicle will cause your vehicle to handle
poorly. The instability could cause a collision. Al-
ways use radial ply tires in sets of four. Never
combine them with other types of tires.

Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a
“mountain/snowflake” symbol on the tire sidewall.If you need snow tires, select tires
equivalent in size and type to the
original equipment tires. Use snow
tires only in sets of four; failure to do
so may adversely affect the safety
and handling of your vehicle.
Snow tires generally have lower speed ratings than
what was originally equipped with your vehicle and
should not be operated at sustained speeds over 75 mph
(120 km/h). For speeds above 75 mph (120 km/h), refer
to original equipment or an authorized tire dealer for
recommended safe operating speeds, loading and cold
tire inflation pressures.
While studded tires improve performance on ice, skid
and traction capability on wet or dry surfaces may be
poorer than that of non-studded tires. Some states
prohibit studded tires; therefore, local laws should be
checked before using these tire types.
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of
inflation pressure. This rapid loss of inflation is referred
to as the Run Flat mode. A Run Flat mode occurs when
the tire inflation pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat mode it has
limited driving capabilities and needs to be replaced
immediately. A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more infor-
mation.
Spare Tires — If Equipped
NOTE: For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to the “Tire Service
Kit” section located in your Owner ’s Information kit for
further information.
