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 Pres- sure 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 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, andspare 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 information on GAWRs, vehicle loading,
and trailer towing, refer to “Vehicle Loading” in the
“Starting And Operating” section of this manual.
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.
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.
Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary
areas are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
234 SERVICING AND MAINTENANCE

is very important. Increased tire pressure and reduced
vehicle loading may be required for high-speed vehicle
operation. Refer to an authorized tire dealer or original
equipment vehicle dealer for recommended safe oper-
ating 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.Tire Repair
If your tire becomes damaged, it may be repaired if it
meets the following criteria:
•
The tire has not been driven on when flat.
• The damage is only on the tread section of your tire
(sidewall damage is not repairable).
•
The puncture is no greater tha na¼ofaninch (6 mm).
Consult an authorized tire dealer for tire repairs and
additional information.
Damaged Run Flat tires, or Run Flat tires that have
experienced a loss of pressure should be replaced
immediately with another Run Flat tire of identical size
and service description (Load Index and Speed Sym-
bol). Replace the tire pressure sensor as well as it is not
designed to be reused.
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
8
SERVICING AND MAINTENANCE 237

limited driving capabilities and needs to be replaced
immediately. A Run Flat tire is not repairable. When a
run flat tire is changed after driving with underinflated
tire condition, please replace the TPM sensor as it is not
designed to be reused when driven under run flat mode
(14 psi (96 kPa)) condition.
NOTE:TPM Sensor must be replaced after driving the
vehicle on a flat tire condition.
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.Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do
not spin your vehicle’s wheels above 30 mph (48 km/h)
or for longer than 30 seconds continuously without
stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of
Emergency” for further information.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause tire
damage or failure. A tire could explode and injure
someone. Do not spin your vehicle’s wheels faster
than 30 mph (48 km/h) for more than 30 seconds
continuously when you are stuck, and do not let
anyone near a spinning wheel, no matter what the
speed.
238 SERVICING AND MAINTENANCE

WARNING!(Continued)
This can cause unpredictable handling and stress
to steering and suspension components. You
could lose control and have a collision resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for your
vehicle.
• Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have a collision.
• Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer read-
ings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring,
Summer, Fall, and Winter). Traction levels may vary
between different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on
the tire sidewall. Use all season tires only in sets of four;
failure to do so may adversely affect the safety and
handling of your vehicle.
Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry
conditions, and are not intended to be driven in snow or
on ice. If your vehicle is equipped with Summer tires, be
aware these tires are not designed for Winter or cold
driving conditions. Install Winter tires on your vehicle
when ambient temperatures are less than 40°F (5°C) or
if roads are covered with ice or snow. For more infor-
mation, contact an authorized dealer.
Summer tires do not contain the all season designation
or mountain/snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four; failure to do so8
