2007 CHEVROLET EQUINOX tire size

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
Your vehicle has a Tire Pressure Monitor
System (TPMS). This system uses radio and
sensor technology to check tire pressure levels.
TPMS sensors are mounted onto each tire
and wheel assembly, except for the spare tire.
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.)
391

When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol on the instrument panel cluster,
and at the same time a message to check
the pressure in a specic tire will appear on the
Driver Information Center (DIC) display. The
low tire pressure warning symbol on the instrument
panel cluster and the check tire pressure
message will appear at each ignition cycle until
the tires are inated to the correct ination
pressure. Using the DIC, tire pressure levels can
be viewed by the driver. For additional information
and details about the DIC operation and displays
seeDIC Operation and Displays on page 193
andDIC Warnings and Messages on page 198.
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 may 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
your vehicle, shows the size of your vehicle’s
original equipment tires and the correct inationpressure for your vehicle’s tires when they are cold.
SeeLoading Your Vehicle on page 315, for an
example of the Tire and Loading Information
Label and its location on your vehicle. Also see
Ination - Tire Pressure on page 390.
Your vehicle’s TPMS system can warn you about a
low tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 396andTires on page 382.
Notice:Do not use a tire sealant if your vehicle
has Tire Pressure Monitors. The liquid sealant
can damage the tire pressure monitor sensors.
The TPMS will not function properly if one or more
of the TPMS sensors are missing or inoperable. If
the system detects a missing or inoperable sensor,
an error message SERVICE TIRE MONITOR
SYSTEM will be shown on the DIC display. If you
have replaced a tire/wheel assembly without
transferring the TPMS sensors, the error message
will be displayed. Once you re-install the TPMS
sensors, the error message should go off. See your
dealer for service if all TPMS sensors are installed
and the error message comes on and stays on.
393

Reset the Tire Pressure Monitor System. See
“TPMS Sensor Matching Process” under
Tire Pressure Monitor System on page 391.
Make certain that all wheel nuts are properly
tightened. See “Wheel Nut Torque” under
Capacities and Specications on page 434.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 404.
When It Is Time for New Tires
One way to tell when it
is time for new tires is
to check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
Some commercial truck
tires may not have
treadwear indicators.
You need a new tire if any of the following
statements are true:
You can see the indicators at three or more
places around the tire.
You can see cord or fabric showing through
the tire’s rubber.
The tread or sidewall is cracked, cut or
snagged deep enough to show cord or fabric.
The tire has a bump, bulge, or split.
The tire has a puncture, cut, or other damage
that cannot be repaired well because of the
size or location of the damage.

{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes, brands, or types (radial
and bias-belted tires), the vehicle may not
handle properly, and you could have a
crash. Using tires of different sizes,
brands, or types may also cause damage
to your vehicle. Be sure to use the correct
size, brand, and type of tires on all
wheels. It is all right to drive with your
compact spare temporarily, as it was
developed for use on your vehicle.
SeeCompact Spare Tire on page 416.
{CAUTION:
If you use bias-ply tires on your vehicle,
the wheel rim anges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.
If you must replace your vehicle’s tires with those
that do not have a TPC Spec number, make
sure they are the same size, load range, speed
rating, and construction type (radial and
bias-belted tires) as your vehicle’s original tires.
Your vehicle’s original equipment tires are listed
on the Tire and Loading Information label.
This label is attached to the vehicle’s center pillar
(B-pillar). SeeLoading Your Vehicle on page 315,
for more information about the Tire and Loading
Information label and its location on your vehicle.

Different Size Tires and Wheels
If you add wheels or tires that are a different size
than your original equipment wheels and tires,
this may affect the way your vehicle performs,
including its braking, ride and handling
characteristics, stability, and resistance to rollover.
Additionally, if your vehicle has electronic
systems such as, anti-lock brakes, traction control,
and electronic stability control, the performance
of these systems can be affected.
{CAUTION:
If you add different sized wheels, your
vehicle may not provide an acceptable
level of performance and safety if tires not
recommended for those wheels are
selected. You may increase the chance
that you will crash and suffer serious
injury. Only use GM specic wheel and
tire systems developed for your vehicle,
and have them properly installed by a
GM certied technician.SeeBuying New Tires on page 398and
Accessories and Modications on page 333for
additional information.
Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.
400

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.
SeeChanging a Flat Tire on page 404for more
information.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your vehicle is
dangerous. You cannot know how it has
been used or how far it has been driven.
It could fail suddenly and cause a crash.
If you have to replace a wheel, use a new
GM original equipment wheel.
Tire Chains
{CAUTION:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle
without the proper amount of clearance
can cause damage to the brakes,
suspension or other vehicle parts. The area
damaged by the tire chains could cause
you to lose control of your vehicle and you
or others may be injured in a crash.
Use another type of traction device only
if its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that
manufacturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it is
contacting your vehicle, and do not spin
your vehicle’s wheels. If you do nd
traction devices that will t, install them
on the front tires.
403

Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence
and to the proper torque specication. See
Capacities and Specifications on page 434for
the wheel nut torque specication.
15. Tighten the wheel
nuts rmly in a
crisscross sequence,
as shown.
16. Lower the jack all the way and remove the
jack from under the vehicle.
17. Tighten the wheel nuts rmly with the wheel
wrench.When reinstalling the wheel cover or center cap
on the full-size tire, tighten all ve plastic caps
hand snug with the aid of the wheel wrench and
tighten them with the wheel wrench an additional
one-quarter of a turn.
Notice:Wheel covers will not t on your
compact spare. If you try to put a wheel cover
on the compact spare, you could damage
the cover or the spare.
Do not try to put a wheel cover on your compact
spare tire. It will not t. Store the wheel cover
in the cargo area until you have the at tire
repaired or replaced.

the rod through the hole. Replace the
rear compartment storage panel/cover and/or
table load oor over the wheel stow rod
through the hole in the oor.
7. Place the at, or damaged tire, face down, on
the load oor with the threaded wheel stow
rod sticking up through the center hole of
the wheel.
8. Install the nut onto the wheel stow rod and
tighten.
9. Install the rear compartment storage
panel/cover in the middle position. See
