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 kilopascals (kPa) before a tire has built up
heat from driving. See Inflation - Tire Pressure
on page 5-62 .
Curb Weight :
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.

pressure to which a cold tire can be inated.
The maximum air pressure is molded onto the
sidewall.
Maximum Load Rating :
The load rating for a tire
at the maximum permissible ination 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 150 lbs (68 kg). See Loading Your Vehicle
on page 4-35 .
Occupant Distribution :
Designated seating
positions.
Outward Facing Sidewall :
The side of an
asymmetrical tire that has a particular side that
faces outward when mounted on a vehicle.
The side of the tire that contains a whitewall, bears
white lettering, or bears manufacturer, brand,
and/or model name molding that is higher
or deeper than the same moldings on the other
sidewall of the tire.
Passenger (P-Metric) Tire :
A tire used on
passenger cars and some light duty trucks and
multipurpose vehicles.
Recommended Ination Pressure :
Vehicle
manufacturer’s recommended tire ination
pressure as shown on the tire placard.
See Inflation - Tire Pressure on page 5-62
and Loading Your Vehicle on page 4-35 .
5-60

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 seated.
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 1/16 inch (1.6 mm) of tread
remains. See When It Is Time for New Tires on
page 5-71 . UTQGS (Uniform Tire Quality Grading
Standards) :
A tire information system that
provides consumers with ratings for a tire’s
traction, temperature, and treadwear. Ratings are
determined by tire manufacturers using
government testing procedures. The ratings are
molded into the sidewall of the tire. See Uniform
Tire Quality Grading on page 5-74 .
Vehicle Capacity Weight :
The number of
designated seating positions multiplied by
150 lbs (68 kg) plus the rated cargo load.
See Loading Your Vehicle on page 4-35 .
Vehicle Maximum Load on the Tire :
Load on
an individual tire due to curb weight, accessory
weight, occupant weight, and cargo weight.
Vehicle Placard :
A label permanently attached
to a vehicle showing the vehicle’s capacity
weight and the original equipment tire size and
recommended ination pressure. See “Tire and
Loading Information Label” under Loading
Your Vehicle on page 4-35 .

Ination - Tire Pressure Tires need the correct amount of air pressure to
operate effectively.
Notice: Do not let anyone tell you that
under-ination or over-ination is all right.
It is not. If your tires do not have enough air
(under-ination), 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-ination),
you can get the following:
Unusual wear
Poor handling
Rough ride
Needless damage from road hazards A vehicle specic Tire and Loading Information
label is attached to your vehicle. This label shows
your vehicle’s original equipment tires and the
correct ination pressures for your tires when they
are cold. The recommended cold tire ination
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, see
Loading Your Vehicle on page 4-35 . 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. See Spare Tire on page 5-98 for additional
information.

Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the
wheel, wheel bolts, and wheel nuts should be replaced.
If the wheel leaks air, replace it (except some
aluminum wheels, which can sometimes be repaired).
See your dealer/retailer if any of these conditions exist.
Your dealer/retailer will know the kind of wheel you need.
Each new wheel should have the same load-carrying
capacity, diameter, width, offset, and be mounted
the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts,
wheel nuts, or Tire Pressure Monitor System (TPMS)
sensors, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts, wheel nuts, and TPMS
sensors for your vehicle. { CAUTION: Using the wrong replacement wheels, wheel
bolts, or wheel nuts on your vehicle can be
dangerous. It could affect the braking and
handling of your vehicle, make your tires lose
air and make you lose control. You could have
a collision in which you or others could be
injured. Always use the correct wheel, wheel
bolts, and wheel nuts for replacement.
Notice: The wrong wheel can also cause problems
with bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper height,
vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
See Changing a Flat Tire on page 5-79 for more
information.
