Tire and Loading Information Label
Label Example
A vehicle specific Tire and Loading Information
label is attached to the center pillar (B-pillar) of
your vehicle. With the driver's door open, you
will find the label attached below the door latch.
This label shows the number of occupant seating
positions (A), and the maximum vehicle capacity
weight (B) in kilograms and pounds. The Tire and Loading Information label also
shows the size of the original equipment tires (C)
and the recommended cold tire inflation
pressures (D). For more information on tires and
inflation see
Tires
on page 6‑62andInflation - Tire
Pressure
on page 6‑70.
There is also important loading information on the
vehicle Certification label. It tells you the Gross
Vehicle Weight Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for the front and rear
axle. See “Certification Label” later in this section.
Steps for Determining Correct Load Limit
1.Locate the statement “The combined weight
of occupants and cargo should never exceed
XXX kg or XXX lbs” on your vehicle's placard.
2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.
3.Subtract the combined weight of the driver
and passengers from XXX kg or XXX lbs.

Tires
Your new vehicle comes with high-quality tires
made by a leading tire manufacturer. If you ever
have questions about your tire warranty and
where to obtain service, see your vehicle
Warranty booklet for details. For additional
information refer to the tire manufacturer.
{WARNING:
.Poorly maintained and improperly used
tires are dangerous.
.Overloading your tires can cause
overheating as a result of too much
flexing. You could have an air-out and
a serious accident. SeeLoading the
Vehicle
on page 5‑28.
(Continued)
WARNING: (Continued)
.Underinflated tires pose the same
danger as overloaded tires. The resulting
accident could cause serious injury.
Check all tires frequently to maintain the
recommended pressure. Tire pressure
should be checked when your tires are
cold. See Inflation - Tire Pressure
on
page 6‑70
.
.Overinflated tires are more likely to be
cut, punctured, or broken by a sudden
impact —such as when you hit a
pothole. Keep tires at the recommended
pressure.
.Worn, old tires can cause accidents.
If your tread is badly worn, or if your tires
have been damaged, replace them.
See High-Speed Operation
on page 6‑72for
inflation pressure adjustment for high speed
driving.
6-62

Low‐Profile Performance Tire
The original equipment tires on your vehicle are
classified as low‐profile performance tires. These
tires are designed for very responsive driving on
wet or dry pavement. You may also notice more
road noise with low‐profile tires and that they tend
to wear faster.
Notice:If the vehicle has low‐profile tires, they
are more susceptible to damage from road
hazards or curb impact than standard profile
tires. Tire and/or wheel assembly damage can
occur when coming into contact with road
hazards like, potholes, or sharp edged objects,
or when sliding into a curb. The vehicle
warranty does not cover this type of damage.
Keep tires set to the correct inflation pressure
and, when possible avoid contact with curbs,
potholes, and other road hazards.
Winter Tires
If you expect to drive on snow or ice covered roads
often, you may want to get winter tires for your vehicle.
All season tires provide good overall performance on
most surfaces but they may not offer the traction you
would like or the same level of performance as winter
tires on snow or ice covered roads. Winter tires, in general, are designed for increased
traction on snow and ice covered roads. With winter
tires, there may be decreased dry road traction,
increased road noise, and shorter tread life. After
switching to winter tires, be alert for changes in
vehicle handling and braking.
See your dealer/retailer for details regarding winter tire
availability and proper tire selection. Also, see
Buying
New Tires on page 6‑77.
If you choose to use winter tires:
.Use tires of the same brand and tread type on all
four wheel positions.
.Use only radial ply tires of the same size, load
range, and speed rating as the original equipment
tires.
Winter tires with the same speed rating as your original
equipment tires may not be available for H, V, W, Y, and
ZR speed rated tires. If you choose winter tires with a
lower speed rating, never exceed the tire's maximum
speed capability.
6-63

(F) Uniform Tire Quality Grading (UTQG):Tire
manufacturers are required to grade tires based
on three performance factors: treadwear, traction
and temperature resistance. For more information
see Uniform Tire Quality Grading
on page 6‑79.
(G) Maximum Cold Inflation Load Limit
:
Maximum load that can be carried and the
maximum pressure needed to support that load.
Tire Size
The following illustration shows an example of a
typical passenger (p‐metric) vehicle tire size.
(A) Passenger (P‐Metric) Tire:The United
States version of a metric tire sizing system.
The letter P as the first character in the tire size
means a passenger vehicle tire engineered
to standards set by the U. S. Tire and Rim
Association. (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 index and speed rating of the
tire. The load index represents the load carry
capacity a tire is certified to carry. The speed
rating is the maximum speed a tire is certified
to carry a load.

Run-Flat Tires
This vehicle, when new, had run-flat tires. There is no
spare tire, no tire changing equipment, and no place to
store a tire in the vehicle. Run-flat tires perform so well
without any air that a Tire Pressure Monitor System
(TPMS) is used to alert you if a tire has lost pressure.
{WARNING:
When the low tire warning light is displayed on
the instrument panel cluster, your vehicle's
handling capabilities will be reduced during
severe maneuvers. If you drive too fast, you could
lose control of your vehicle. You or others could
be injured. Do not drive over 55 mph (90 km/h)
when the low tire warning light is displayed.
Drive cautiously and check your tire pressures
as soon as you can.
If a tire goes flat, you will not need to stop on the side
of the road to change the tire. You can just keep on
driving. The shorter the distance you drive and the
slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated
run-flat tire for 25 miles (40 km) or less and at speeds of
55 mph (90 km/h) or less, there is a good chance that
the tire can be repaired. The tires on coupe, convertible
and Z06 models can operate effectively with no air
pressure for up to 100 miles (160 km) at speeds up
to 55 mph (90 km/h), but the tire would then have to
be replaced. The tires on ZR1 models can operate
effectively with no air pressure for up to 50 miles
(80 km) at speeds up to 55 mph (90 km/h), but the tire
would then have to be replaced. When a tire is filled
with air, it provides a cushion between the road and the
wheel. Because you will not have this cushion when
driving on a deflated tire, try to avoid potholes that could
damage your wheel and require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you have driven
on the tire in a deflated condition. When a tire has
been damaged, or if you have driven any distance on
a run-flat tire, check with an authorized run-flat tire
service center to determine whether the tire can be
repaired or should be replaced. To maintain your
vehicle's run-flat feature, all replacement tires must
be self-supporting tires. As soon as possible,
contact the nearest authorized GM or run-flat servicing
facility for inspection and repair or replacement.
6-69

To locate the nearest GM or run-flat servicing facility,
call Roadside Assistance. For phone numbers and
Roadside Service details see Roadside Assistance
Program
on page 8‑7.
{WARNING:
Run-flat tires are constructed differently than other
tires and could explode during improper service.
You or others could be injured or killed if you
attempt to repair, replace, dismount, or mount
a run-flat tire. Let only an authorized run-flat
service center repair, replace, dismount, and
mount run-flat tires.
The valve stems on your run-flat tires have sensors that
are part of the Tire Pressure Monitor System (TPMS).
See Tire Pressure Monitor System
on page 6‑72.
These sensors contain batteries which are designed
to last for 10 years under normal driving conditions. See
your dealer/retailer if you ever need to have a wheel
replaced, or if the sensors ever need replacement.
Notice: Using liquid sealants can damage the tire
valves and tire pressure monitor sensors in the
vehicle's run-flat tires. This damage would not be
covered by warranty. Do not use liquid sealants in
the vehicle's run-flat tires.
Inflation - Tire Pressure
Tires need the correct amount of air pressure to
operate effectively.
Notice:Do not let anyone tell you that
under‐inflation or over‐inflation is all right.
It is not. If your tires do not have enough air
(under‐inflation), you can get the following:
.Too much flexing
.Too much heat
.Tire overloading
.Premature or irregular wear
.Poor handling
.Reduced fuel economy
If your tires have too much air (over‐inflation),
you can get the following:
.Unusual wear
.Poor handling
.Rough ride
.Needless damage from road hazards
