When it’s Time for New Tires
You need a new tire if:
Tread Wear
Indicators
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
1/16 inch (1.6
mm)
or less of tread
remaining.
0 You can see the indicators at three or more places around the tire.
0 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 can‘t be repaired well
because
of the size or location of the damage.
Dual Tire Operation
When the vehicle is new, or whenever a wheel, wheel bolt or wheel nut is
replaced, check the wheel
nut torque after 100, 1,000 and 6,000 miles (160,
1 600 and 10 000 km) of driving. For proper torque see “Wheel Nut
Torque” in the Index.
The outer tire
on a dual wheel setup generally wears faster than the inner
tire. Your tires will wear more evenly and last longer
if you rotate the tires
periodically. If you’re going to be doing
a lot of driving on high-crown
roads, you can reduce tire wear by adding
5 psi (35 kPa) to the tire pressure
in the outer tires. Be sure to return
to the recommended pressures when no
longer driving under those conditions.

A CAUTION:
If you operate your vehicle with a tire that is badly
underinflated, the tire can overheat. An overheated tire
can lose
air suddenly or catch fire. You or others could be injured. Be
sure all tires (including the spare, if any) are properly inflated.
Buying New Tires
To find out what kind and size of tires you need, look at the
CertificationRire label.
The tires installed on your vehicle when
it was new a Tire Performance
Criteria Specification (TPC Spec) number on each tire’s sidewall. When you
get new tires, get ones with that same 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 number will be followed by an
“MS” (for mud and snow).
If you ever replace your tires with those not having a TPC Spec number,
make sure they are the same. size, load range, speed rating and construction
type (bias, bias-belted or radial) as your original tires.
I A CAUTION:
Mixing tires could cause you to lose control while driving. If you
mix tires of different sizes or types (radial and bias-belted tires),
the vehicle may not handle properly, and you could have
a crash.
Be sure to use the same size and type tires on all four wheels.
Uniform Tire Quality Grading
The following information relates to the system developed by the United
States National Highway Traffic Safety Administration which grades tires
by treadwear, traction and temperature performance.
(This applies only to
vehicles sold in the United States.)

Whenever a wheel, wheel bolt or wheel nut is replaced on a dual wheel
setup, check the wheel nut torque after 100, 1,000 and 6,000 miles ( 160,
1 600 and 10 000 km) of driving. For proper torque, see “Wheel Nut
Torque” in the Index.
Used Replacement Wheels
A CAUTION:
Putting a used wheel on your vehicle is dangerous. You can’t
know
how it’s been used or how many miles it’s been driven. It
could fail suddenly and cause an accident. If you have to replace
a wheel use a new GM original equipment wheel.

c
‘ire Chains
NOTICE:
If your vehicle has dual wheels or LT265/75R16 size tires, don’t
use tire chains; they can damage your vehicle.
If you don’t have dual wheels or if you have a tire size other
than
LT26975R16, use tire chains only where legal and only
when you must. Use chains that are the proper size for your
tires. Install them on the tires of the rear axle.
Don’t use chains on the tires
of the front axle.
Tighten them
as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain manufacturer’s
instructions. If you can hear the chains contacting your vehicle,
stop and retighten them. If the contact continues, slow down
until it stops. Driving too fast
or spinning the wheels with chains
on
will damage your vehicle.
