EXAMPLE:
Service Description: 95= Load Index
– A numerical code associated with the maximum load a tire can carry
H = Speed Symbol
– A symbol indicating the range of speeds at which a tire can carry a load corresponding to
its load index under certain operating conditions
– The maximum speed corresponding to the speed symbol should only be achieved under
specified operating conditions (i.e., tire pressure, vehicle loading, road conditions, and
posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL)
tire:
• XL = Extra load (or reinforced) tire, or
• LL = Light load tire or
• C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this
tire

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 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
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, 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 “Start-
ing And Operating”, or the Tire Information Supple-
ment, located in your Owner ’s Information kit.
NOTE: Under a maximum loaded vehicle condition,
gross axle weight ratings (GAWRs) for the front and
rear axles must not be exceeded. Refer to “Vehicle
Loading” in “Starting And Operating”, or the Tire
Information Supplement located in your Owner ’s Infor-
mation kit, for further information on GAWRs, vehicle
loading, and trailer towing.
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.

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
• Tread Wear
• Ride Comfort
Safety
WARNING!
•Improperly inflated tires are dangerous and can
cause collisions.
• Underinflation increases tire flexing and can re-
sult in overheating and tire failure.
• Overinflation reduces a tire’s ability to cushion
shock. Objects on the road and chuckholes can
cause damage that result in tire failure.
(Continued)
WARNING! (Continued)
•Overinflated or underinflated tires can affect ve-
hicle handling and can fail suddenly, resulting in
loss of vehicle control.
• Unequal tire pressures can cause steering prob-
lems. You could lose control of your vehicle.
• Unequal tire pressures from one side of the ve-
hicle to the other can cause the vehicle to drift to
the right or left.
• Always drive with each tire inflated to the recom-
mended cold tire inflation pressure.
Both under-inflation and over-inflation affect the stabil-
ity of the vehicle and can produce a feeling of sluggish
response or over responsiveness in the steering.
NOTE:
• Unequal tire pressures from side to side may cause
erratic and unpredictable steering response.
• Unequal tire pressure from side to side may cause the
vehicle to drift left or right.

Fuel Economy
Underinflated tires will increase tire rolling resistance
resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause abnor-
mal wear patterns and reduced tread life, resulting in
the need for earlier tire replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable ride.
Over-inflation produces a jarring and uncomfortable
ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on the
driver’s side B-Pillar or rear edge of the driver’s side
door.
At least once a month:
•Check and adjust tire pressure with a good quality
pocket-type pressure gauge. Do not make a visual
judgement when determining proper inflation. Tires
may look properly inflated even when they are
under-inflated. •
Inspect tires for signs of tire wear or visible damage.
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will pre-
vent moisture and dirt from entering the valve stem,
which could damage the valve stem.
Inflation pressures specified on the placard are always
“cold tire inflation pressure”. Cold tire inflation pres-
sure 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. The cold tire inflation pressure must not exceed
the maximum inflation pressure molded into the tire
sidewall.
Check tire pressures more often if subject to a wide
range of outdoor temperatures, as tire pressures vary
with temperature changes.
Tire pressures change by approximately 1 psi (7 kPa)
per 12°F (7°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage,
especially in the Winter.
