10-58 Vehicle Care
This could be an early indicator that
the air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tire and Loading Information
label shows the size of the original
equipment tires and the correct
inflation pressure for the tires when
they are cold. SeeVehicle Load
Limits on page 9‑14, for an example
of the Tire and Loading Information
label and its location. Also see Tire
Pressure on page 10‑54.
The TPMS can warn about
a low tire pressure condition but
it does not replace normal tire
maintenance. See Tire Inspection
on page 10‑61, Tire Rotation on
page 10‑61, and Tires on
page 10‑48. Notice:
Tire sealant materials are
not all the same. A non-approved
tire sealant could damage the
TPMS sensors. TPMS sensor
damage caused by using
an incorrect tire sealant is
not covered by the vehicle
warranty. Always use only
the GM-approved tire sealant
available through your dealer
or included in the vehicle.
Factory-installed Tire Inflator Kits
use a GM-approved liquid tire
sealant. Using non-approved tire
sealants could damage the TPMS
sensors. See Tire Sealant and
Compressor Kit on page 10‑71 for
information regarding the inflator
kit materials and instructions.TPMS Malfunction Light and
Message
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When
the system detects a malfunction,
the low tire pressure warning light
flashes for about one minute and
then stays on for the remainder
of the vehicle on/off cycle. A DIC
warning message also displays.
The malfunction light and DIC
warning message come on at
each vehicle on/off cycle until the
problem is corrected. Some of the
conditions that can cause these to
come on are:
.One of the road tires has
been replaced with the spare
tire, if the vehicle has one.
The spare tire does not
have a TPMS sensor.

Vehicle Care 10-61
Tire Inspection
GM recommends that the
tires, including the spare, be
inspected for signs of wear or
damage at least once a month.
Replace the tire if:
.The indicators at three or
more places around the tire
can be seen.
.There is 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.
Tire Rotation
Tires should be rotated every
12 000 km (7,500 mi). The first
rotation is the most important.
SeeScheduled Maintenance on
page 11‑2.
Tires are rotated to achieve a
more uniform wear for all tires.
Any time unusual wear is
noticed, rotate the tires as
soon as possible, and
check the wheel alignment.
See When It Is Time for New
Tires on page 10‑62 andWheel
Replacement on page 10‑67.
Use this rotation pattern when
rotating the tires.
Adjust the front and rear tires
to the recommended inflation
pressure on the Tire and
Loading Information label
after the tires have been
rotated. See Tire Pressure on
page 10‑54 andVehicle Load
Limits on page 9‑14.
Reset the Tire Pressure Monitor
System. See Tire Pressure
Monitor Operation on
page 10‑57.

Black plate (64,1)Chevrolet Volt Owner Manual - 2011
10-64 Vehicle Care
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
vehicle, including brake system
performance, ride and handling,
traction control, and tire pressure
monitoring performance. GM's TPC
Spec number is molded onto the
tire's sidewall near the tire size.
If the tires have an all‐season
tread design, the TPC spec number
will be followed by MS, for mud
and snow. SeeTire Sidewall
Labeling on page 10‑49 for
additional information.
GM recommends replacing all the
tires at the same time. Uniform
tread depth on all tires will help
to maintain the performance of
the vehicle. Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
See Tire Inspection on page 10‑61
and Tire Rotation on page 10‑61 for
information on proper tire rotation.{WARNING
Tires could explode during
improper service. Attempting to
mount or dismount a tire could
cause injury or death. Only your
dealer or authorized tire service
center should mount or dismount
the tires.
{WARNING
Mixing tires of different sizes,
brands, or types may cause
loss of control of the vehicle,
resulting in a crash or other
vehicle damage. Use the
correct size, brand, and type
of tire on all wheels.
{WARNING
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
A tire and/or wheel could fail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be replaced
with a tire that does not have a TPC
Spec number, make sure they are
the same size, load range, speed
rating, and construction (radial) as
the original tires.
Vehicles that have a tire pressure
monitoring system could give an
inaccurate low‐pressure warning
if non‐TPC Spec rated tires are
installed. See Tire Pressure Monitor
System on page 10‑55.

Vehicle Care 10-65
The Tire and Loading Information
Label indicates the original
equipment tires on the vehicle.
SeeVehicle Load Limits on
page 9‑14, for the label location
and more information about the
Tire and Loading Information label.
Different Size Tires and
Wheels
If wheels or tires are installed that
are a different size than the original
equipment wheels and tires, vehicle
performance, including its braking,
ride and handling characteristics,
stability, and resistance to rollover
may be affected. If the vehicle has
electronic systems such as antilock
brakes, rollover airbags, traction
control, and electronic stability
control, the performance of these
systems can also be affected.
{WARNING
If different sized wheels are used,
there may not be an acceptable
level of performance and safety
if tires not recommended for
those wheels are selected.
This increases the chance
of a crash and serious injury.
Only use GM specific wheel
and tire systems developed
for the vehicle, and have them
properly installed by a GM
certified technician.
See Buying New Tires on
page 10‑63 andAccessories
and Modifications on page 10‑4
for 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.

Vehicle Care 10-69
Used Replacement Wheels
{WARNING
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
Tire Chains
{WARNING
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(Continued)
WARNING (Continued)
parts. The area damaged by
the tire chains could cause
loss of control and a crash.
Use another type of traction
device only if its manufacturer
recommends it for the vehicle's
tire size combination and
road conditions. Follow that
manufacturer's instructions.
To avoid vehicle damage, drive
slow and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used,
install them on the front tires.
If a Tire Goes Flat
This vehicle has a tire sealant and
compressor kit. SeeTire Sealant
and Compressor Kit on page 10‑71.
There is no spare tire, no tire
changing equipment, and no
place to store a tire.
To properly lift this vehicle, see
Lifting the Vehicle on page 10‑5.
It is unusual for a tire to blowout
while driving, especially if the
tires are maintained properly.
See Tires on page 10‑48.
If air goes out of a tire, it is much
more likely to leak out slowly.
