Two labels on your vehicle show how
much weight
it may properly carry. The
Tire-Loading Information label found
on
the rear edge of the driver's door
tells
you the proper size, speed rating
and recommended inflation pressures
€or the tires
on your vehicle. It also
gives you impartant information about
the number
of people that can be in
your vehicle and the total weight that
you can carry. This weight is called the
Vehicle Capacity Weight and includes
the weight of all occupants, cargo, and
all nonfactory-installed options. The other
label is the Certification label,
also on the rear
edge of the driver's
door. It
tells you the gross weight
capacity of
your vehicle, called the
GVWR (Gross Vehicle Weight Rating).
The
GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
Never exceed the GVWR
for your
vehicle, or the Gross Axle Weight
Rating
(GAWR) for either the front or
rear axle.
And, if you do have a heavy load, you
should spread it out. Don't carry more
than
100 lbs. (45 kg) in the rear area of
your Corvette.

When It’s Time.for New Tires
One way to tell when it’s time for new
tires is to check the treadwear indicators,
which will appear when your tires have
only%2 inch (1.6 mm) or less of tread
remaining.
You need a new tire if:
* You can see the indicators at three
You can see cord or fabric showing
The tread or sidewall is cracked, cut
places around the tire.
through the
tire’s rubber.
or snagggd 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 can’t he repaired well
because
of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label. The
tires installed on
your vehicle when it was new had a Tire
Per€omance
Criteria Specification
(TPC Spec) number on each tire’s
sidewall. When
you get new tires, get
ones with that sme TPC Spec number.
That way, your vehicle will continue to
have
tires that are designed to give
proper endurance, handling, speed
rating, traction, ride and other things
during normal service on your vehicle.
If your tires have an all-season tread
design, the TPC Spec number will be
followed by an “MS” (for mud and
snow).
. ... r .: ;.- - .
If yuu ever replace your tires with those
,not having a TPC Spec number, make
SLUT they are the same size, load range,
speed rating and construction
type
(bias, bias-belted or radial) as your
original tires.

Unijiim Tire Quality
Grading
The following information relates to the
system developed by the United States
National
Highway Tr&c Safety
Administration which grades tires by
treadwear, traction and temperature
performance. (This applies only
to
vehicles sold in the United States.)
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
wh on
a specified government test course.
For example, a tire graded 150 would
wear one
and a half (1%) times as well
on the govement course as a tire
graded
100. Therelative performance of
tires depends upon the actual
conditions
of their use, however, and
may depart significantly from the norm
due to variations in driving habits,
service practices and differences in road
characteristics and climate.
