2007 CHEVROLET CORVETTE tire size

Tire Rotation
The tires on your vehicle are different sizes front
to rear. Due to this, your tires should not be
rotated. Each tire and wheel should be used
only in the position it is in.
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.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.

Buying New Tires
GM has developed and matched specic tires
for your vehicle. The original equipment tires
installed on your vehicle, when it was new,
were designed to meet General Motors Tire
Performance Criteria Specication (TPC spec)
system rating. If you need replacement tires,
GM strongly recommends that you get tires with
the same TPC Spec rating. This way, your vehicle
will continue to have tires that are designed to
give the same performance and vehicle safety,
during normal use, as the original tires.
GM’s exclusive TPC Spec system considers over
a dozen critical specications that impact the
overall performance of your 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 by the tire manufacturer.
If the tires have an all-season tread design,
the TPC spec number will be followed by an
MS for mud and snow. SeeTire Sidewall
Labeling on page 380for additional information.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
snow tires with a lower speed rating, never
exceed the tire’s maximum speed capability.
{CAUTION:
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes (other than those originally
installed on your vehicle), 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 (other than those originally
installed on your vehicle), brands or
types, may also cause damage to your
vehicle. Be sure to use the correct size,
brand, and type tires on all four wheels.
394

{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.Vehicles that have a tire pressure monitoring
system may give an inaccurate low-pressure
warning if non-TPC spec rated tires are installed
on your vehicle. Non-TPC Spec rated tires
may give a low-pressure warning that is higher or
lower than the proper warning level you would
get with TPC Spec rated tires. SeeTire Pressure
Monitor System on page 389.
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 309
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 394and
Accessories and Modications on page 319
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. 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.
396

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.
CAUTION: (Continued)
CAUTION: (Continued)
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, re-adjust or remove the
device if it is contacting your vehicle,
and do not spin your wheels. If you
do nd traction devices that will t,
install them on the rear tires.
