TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire inflation
pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in section
8. All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
OMG055004
WARNING - Tire underin-
flation
Severe underinflation can lead
to severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Wheel alignment and tire balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to
have your wheels aligned again.
However, if you notice unusual tire
wear or your vehicle pulling one way
or the other, the alignment may need
to be reset.
If you notice your vehicle vibrating
when driving on a smooth road, your
wheels may need to be rebalanced. Tire replacement
If the tire is worn evenly, a tread wear
indicator will appear as a solid band
across the tread. This shows there is
less than 1.6 mm (1/16 inch) of tread
left on the tire. Replace the tire when
this happens.
Do not wait for the band to appear
across the entire tread before replac-
ing the tire.
CAUTION
Improper wheel weights can
damage your vehicle's alu-minum wheels. Use onlyapproved wheel weights.
OEN076053
Tread wear indicatorWARNING - Replacing tires
To reduce the chance or serious
or fatal injuries from an acci-
dent caused by tire failure or
loss of vehicle control:
Replace tires that are worn, show uneven wear, or are
damaged. Worn tires can
cause loss of braking effec-
tiveness, steering control, and
traction.
Do not drive your vehicle with too little or too much pressure
in your tires. This can lead to
uneven wear and tire failure.
When replacing tires, never mix radial and bias-ply tires
on the same car. You must
replace all tires (including the
spare) if moving from radial to
bias-ply tires.

Tire terminology and definitions
Air Pressure: The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
pounds per square inch (psi) or kilo-
pascal (kPa).
Accessory Weight : This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic
transaxle, power seats, and air con-
ditioning.
Aspect Ratio : The relationship of a
tire's height to its width.
Belt: A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead: The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire : A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread. Cold Tire Pressure: The amount of
air pressure in a tire, measured in
pounds per square inch (psi) or kilo-
pascals (kPa) before a tire has built
up heat from driving.
Curb Weight: This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings: The DOT code
includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.
GVWR: Gross Vehicle Weight Rating
GAWR FRT: Gross Axle Weight
Rating for the Front Axle.
GAWR RR: Gross Axle Weight
Rating for the Rear axle.
Intended Outboard Sidewall
: The
side of an asymmetrical tire, that
must always face outward when
mounted on a vehicle.
Kilopascal (kPa): The metric unit for
air pressure.
Load Index: An assigned number
ranging from 1 to 279 that corre-
sponds to the load carrying capacity
of a tire.
Maximum Inflation Pressure : The
maximum air pressure to which a
cold tire may be inflated. The maxi-
mum air pressure is molded onto the
sidewall.
Maximum Load Rating : The load
rating for a tire at the maximum per-
missible inflation pressure for that
tire.
Maximum Loaded Vehicle Weight:
The sum of curb weight; accessory
weight; vehicle capacity weight; and
production options weight.
Normal Occupant Weight: The
number of occupants a vehicle is
designed to seat multiplied by 68 kg
(150 pounds).

745
Maintenance
Occupant Distribution: Designated
seating positions.
Outward Facing Sidewall: The side
of a asymmetrical tire that has a par-
ticular side that faces outward when
mounted on a vehicle. The outward
facing sidewall bears white lettering
or bears manufacturer, brand, and/or
model name molding that is higher or
deeper than the same moldings on
the inner facing sidewall.
Passenger (P-Metric) Tire : A tire
used on passenger cars and some
light duty trucks and multipurpose
vehicles.
Recommended Inflation Pressure :
Vehicle manufacturer's recommend-
ed tire inflation pressure and shown
on the tire placard.
Radial Ply Tire : A pneumatic tire in
which the ply cords that extend to the
beads are laid at 90 degrees to the
centerline of the tread.
Rim: A metal support for a tire and
upon which the tire beads are seat-
ed.
Sidewall: The portion of a tire
between the tread and the bead. Speed Rating: An alphanumeric
code assigned to a tire indicating the
maximum speed at which a tire can
operate.
Traction: The friction between the
tire and the road surface. The
amount of grip provided.
Tread: The portion of a tire that
comes into contact with the road.
Treadwear Indicators: Narrow
bands, sometimes called "wear
bars," that show across the tread of a
tire when only 2/32 inch of tread
remains.
UTQGS: Uniform Tire Quality
Grading Standards, a tire information
system that provides consumers with
ratings for a tire's traction, tempera-
ture and treadwear. Ratings are
determined by tire manufacturers
using government testing proce-
dures. The ratings are molded into
the sidewall of the tire.
Vehicle Capacity Weight
: The num-
ber of designated seating positions
multiplied by 68 kg (150 lbs.) plus the
rated cargo and luggage load. Vehicle Maximum Load on the
Tire: Load on an individual tire due to
curb and accessory weight plus
maximum occupant and cargo
weight.
Vehicle Normal Load on the Tire
:
Load on an individual tire that is
determined by distributing to each
axle its share of the curb weight,
accessory weight, and normal occu-
pant weight and driving by 2.
Vehicle Placard: A label permanent-
ly attached to a vehicle showing the
original equipment tire size and rec-
ommended inflation pressure.
