2009 PONTIAC VIBE tire size

Loading the Vehicle
It is very important to know how
much weight your vehicle can
carry. Two labels on the vehicle
show how much weight it may
properly carry, the Tire and
Loading Information label and
the Certication label.
{CAUTION
Do not load the vehicle any
heavier than the Gross Vehicle
Weight Rating (GVWR), or
either the maximum front or
rear Gross Axle Weight Rating
(GAWR). If you do, parts on
the vehicle can break, and it
can change the way your
vehicle handles. These could
cause you to lose control and
crash. Also, overloading can
shorten the life of the vehicle.Tire and Loading Information
Label
A vehicle specic Tire and
Loading Information label is
attached to the vehicle’s center
pillar (B-pillar). With the driver’s
door open you will nd the label
attached below the door lock post
(striker). The Tire and Loading
Information label shows the
number of occupant seatingpositions (A), and the maximum
vehicle capacity weight (B) in
kilograms and pounds. This
weight includes the weight of
all occupants, cargo, and all
nonfactory-installed options.
The Tire and Loading
Information label also shows the
tire size of the original equipment
tires (C), and the recommended
cold tire ination pressures (D).
For more information on tires and
ination seeTires on page 9-41
andInflation - Tire Pressure on
page 9-47.
There is also important loading
information on the Certication
label. It tells you the Gross
Vehicle Weight Rating (GVWR)
and the Gross Axle Weight
Rating (GAWR) for the front
and rear axle. See “Certication
Label” later in this section.

Tire Size
The following illustration
shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire
:The United States version of a
metric tire sizing system. The
letter P as the rst character in
the tire size means a passenger
vehicle tire engineered to
standards set by the U.S. Tire
and Rim Association. Tires
engineered to European
standards do not use the
letter P as the rst character
in the tire size.(B) Tire Width
:The three-digit
number indicates the tire section
width in millimeters from sidewall
to sidewall.
(C) Aspect Ratio
:A two-digit
number that indicates the tire
height-to-width measurements.
For example, if the tire size
aspect ratio is 60, as shown in
item C of the illustration, it would
mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code
:A letter
code is used to indicate the type
of ply construction in the tire.
The letter R means radial ply
construction; the letter D means
diagonal or bias ply construction;
and the letter B means
belted-bias ply construction.
(E) Rim Diameter
:Diameter of
the wheel in inches.(F) Service Description
:These
characters represent the load
range and speed rating of the
tire. The load index represents
the load carry capacity a tire is
certied to carry. The load index
can range from 1 to 279. The
speed rating is the maximum
speed a tire is certied to carry
a load. Speed ratings range
fromAtoZ.
Tire Terminology and
Denitions
Air Pressure:The amount of air
inside the tire pressing outward
on each square inch of the tire.
Air pressure is expressed in
pounds per square inch (psi)
or kilopascal (kPa).
Accessory Weight
:This means
the combined weight of optional
accessories. Some examples
of optional accessories are,
automatic transmission, power
steering, power brakes, power
windows, power seats, and air
conditioning.
9-44 Vehicle Service and Care
2009 - Pontiac Vibe Owner Manual

Vehicle Capacity Weight:The number of designated
seating positions multiplied
by 150 lbs (68 kg) plus the rated
cargo load. SeeLoading the
Vehicle on page 8-32.
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”
underLoading the Vehicle
on page 8-32.
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
hazardsA 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, seeLoading
the Vehicle on page 8-32.
How you load your vehicle
affects vehicle handling and
ride comfort. Never load your
vehicle with more weight than
it was designed to carry.
Vehicle Service and Care 9-47
2009 - Pontiac Vibe Owner Manual

When to Check
Check your tires once a month
or more. Do not forget to
check the compact spare tire,
it should be at 60 psi (420 kPa).
For additional information
regarding the compact spare
tire, seeCompact Spare Tire
on page 9-70.
How to Check
Use a good quality pocket-type
gage to check tire pressure.
You cannot tell if your tires are
properly inated simply by
looking at them. Radial tires may
look properly inated even when
they are under-inated. Check
the tire’s ination pressure when
the tires are cold. Cold means
your vehicle has been sitting for
at least three hours or driven no
more than 1 mile (1.6 km).Remove the valve cap from the
tire valve stem. Press the tire
gage rmly onto the valve to
get a pressure measurement.
If the cold tire ination pressure
matches the recommended
pressure on the Tire and Loading
Information label, no further
adjustment is necessary. If the
ination pressure is low, add air
until you reach the recommended
amount.
If you overll the tire, release air
by pushing on the metal stem
in the center of the tire valve.
Re-check the tire pressure with
the tire gage.
Be sure to put the valve caps
back on the valve stems.
They help prevent leaks by
keeping out dirt and moisture.Tire Pressure Monitor
System
The Tire Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tire pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle’s
tires and transmit tire pressure
readings to a receiver located
in the vehicle.
Each tire, including the spare
(if provided), should be checked
monthly when cold and inated to
the ination pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire ination
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire ination pressure label, you
should determine the proper tire
ination pressure for those tires.)
9-48 Vehicle Service and Care
2009 - Pontiac Vibe Owner Manual

The TPMS operates on a radio
frequency and complies with
RSS-210 of Industry and Science
Canada. Operation is subject to
the following two conditions:
1. This device may not cause
interference.
2. This device must accept any
interference received, including
interference that may cause
undesired operation of the device.
Changes or modications to
this system by other than an
authorized service facility could void
authorization to use this equipment.
Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(TPMS) warns the driver when a low
tire pressure condition exists. TPMS
sensors are mounted onto each tire
and wheel assembly, excluding the
spare tire and wheel assembly.When a low tire pressure condition
is detected, the low tire pressure
warning light, located on the
instrument panel cluster, comes on.
This light also comes on for a
few seconds and then goes off when
you turn the ignition to ON/RUN.
This indicates the TPMS is
functioning properly. If the low-tire
pressure warning light comes on
while driving the vehicle, the system
may have detected a low-tire
condition. You need to stop as soon
as possible and check the tires.
The low tire pressure warning light
may come on in cool weather when
the vehicle is rst started, and
then turn off as you start to drive.This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inated
to the proper pressure.
A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
ination pressure for the tires when
they are cold. SeeLoading the
Vehicle on page 8-32, for an
example of the Tire and Loading
Information label and its location on
your vehicle. Also seeInflation - Tire
Pressure on page 9-47.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. SeeTire Inspection
and Rotation on page 9-53andTires
on page 9-41.
