4. Always use a tire pressure gage when checking inflation pressures (we
suggest
you purchase a quality pocket-type gage). Simply looking at the
tires to check inftation pressures is not enough , especially with radia l tires .
Underinflated radial tires may
look like correctly inflated radial tires. H the.
inflation pressure on a tire is often low , have your d9aler correct the cause.

5. Be sure to put the tire inflation valve caps back on, if so equipped. This
will help keep dirt · and moisture from getting into the valve core which
could cause a leak.
6. If an air loss occurs while driving, do not drive on the flat tire more than is
needed to stop safely. Driving even a short distance
ona flat tire can
damage a tire and wheel beyond repair.
Inspection and Rotation
Front and rear tires perlorm different jobs and can wear differently depending
on the types of roads driven , your driving habits, etc .
For longer tire
life, you should inspect and rotate your tires as recommended in
Section A of the Maintenance Schedule folder. Many car and tire dealers will perform a free tire inspection to look for uneven or abnormal tire wear (usually
caused
by wrong inflation pressures, lack of regular rotation, improper wheel
alignment, out
of balance tires, or poor driving habits).
After rotation , adjust the front
and. rear tire pressures (see the Tire Placard)
and be sure to check wheel nut tightness . (Wheel nuts should also be
tightened at certain intervals; see the Wheel Nut Torque Caution in "In Case of
Emergency" section,
page 3·7, for further information.)

brushing. Installing wheels without good metaHo-metal contact at the mounting surfaces
can cause wheel nuts to loosen, which can . later allow a wheel to come off while the vehicle is moving, possibly causing loss of control. (Also see the "Wheel Nut Torque"
Caution in "In Case of Emergency," Section 3 of this manual, on page 3·7.)

Alignment and Balance
Proper wheel alignment· improves tire tread. mileage. Your vehicle's suspension
parts should be inspected often and aligned when needed. (See the Maintenance Schedule Folder for more information.) Ball joints have built-in wear indicators and some movement in the joints is normal. Improper
alignrnentwill not cause the vehicle to vibrate. However, improper ~Iignment can cause:
• the tires to roll at an angle, which will result in faster tire wear;
• your tires to wear unevenly;
• your vehicle to "pull" to the left or right. .
Proper tire balancing provides the best riding comfort and helps reduce tire
tread· wear. Out-of-balance tires can cause annoying vibration and uneven tire wear such as cupping and flat spots.
Traction
Driving, cornering, and braking traction are reduced when water, snow, ice,
gravel, or other material is on the road. Adjust driving practices and vehicle speed to road conditions.
When driving on wet or slushy roads,a wedge of water can build up between
the tire and road. This is known as hydroplaning, and may cause partial or complete loss of traction, vehicle control, and stopping ability.
To reduce
the chance of traction loss, follow these tips:
1. Slowdown during rainstorms or when roads are slushy.
2. Slow down if the road has standing water or puddles.
3. Replace the tires when the tread wear indicators are showing.
4. Keep the tires properly inflated.

your tires were designed to provide better snow traction than bias or
bias­
belled tir~ wijhout snow treed. However, ij you use conventional snow tires,
be sure they are the same size, ioadrange , and construction type (bias, bias­belted, or radial) as your other tires .
Tire Chains or Similar Traction Devices
Use of chains may adversely affect your vehicle's handling. When using
chains:
(1) adjust speed to road conditions, (2) avoid sharp turns, and (3) when possible, avoid locked-wheel biaking.
I~ addition , to help prevent chain damage to your vehicle:
• Inslall the chains on the 'rear tires as tightly as possible , then tighten them
again af1er driving 1 /4 to 1 /2 mile «}:4t6·(} .. 8 kilometer) . The use 01 chains
on the front tires is not recommended; the chains may contact
and possibly
damage the vehicle :
If you intend to use chains on the front tires; be sure ther~ is enough clearance.
• Danai exceed 45 mph (70 krn/h), or the chain manufacturer's speed' limit, if lower.
•
Drive in a restrained manner and avoid large bumps, potholes, severe turns .
and other manuevers wliich could cause the tires to bounce up and down.
• Follow any other instructions 'of il1li -chain manufacturer which do not
disagree with the above.
n you buy tire chains, make sure the side chain fasteners are not wider than
the side chain
links; otherwise, the .chains may contact and possill!y.d~age. your vehicle. • .

CAlITION: Do not mix different tire construction types (such as radial, bias, artd bl .. belted) on your vehicle except In emergenci •• , bee.UN your vehicle's handling could be aftKtedandmay resun"in loea o':control. ThiscauUon does not apply to a stowaway ; compact, or temporary spare Ore furnished with your vehicle.
On most vehicles originally equipped wijh radial .tires, you will find a TPC Spec . No. (Tire Performance Crijeria Specijication Number) molded into the tire
sidewall near the tire size marking . This shows that the tire meets rigid size
and performance standards which
weredevelopelffor your vehicle . The TPC
Spec. No: assures a proper combination of endurance , handling, load capacity,
ride and traction on wet, dry, and snow-covered surfaces. When you replace
your tires with tires having the
same TPC Sp~. No., your new tires will be
cOrTlpatible with your vehicle .
5-15

Downloaded from www.Manualslib.com manuals search engine When replacing tires with those not having a TPC Spec. No., you should use
the same size,
load range, and constructiontype (bias, bias-bened, or radial)
as the original tires on your
vehicle . Although ~ is not generaly recommended ,
some alpha-size and metric-size tires can be interchanged. (For size
equivalency, contact your Chevrolet
dealer or a tire dealer) . A different size or
type of tire may affect ride,
handling, speedometer /odometer calibration,
vehicle ground clearance , and tire or tire chain clearance to the body or
chassis .
II replacing only a single tire, it should be paired on the same axle with the least worn tire of the other three.
UNIFORM TIRE QUALITY GRADING
The following information relates to the tire grading system developed by the
National Highway Traffic Safety' Adminlslration which will grade tires by
treadwear, traction and temperature performance.
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire
when tested under
controlled conditions on a specified government test
course . For example, the tire graded 150 would wear one and a haij (1-1/2)
times as well on the government course as a tire graded 100. The relative
performance of tires depends upon the. actual conditions of their _ use , however ,
and may depart significanlly from the norm due to variations in driving habits , service practices and. differences in road characteristics and climate.
TRACTION -A, B,C
. T~~tr~ction grades, from highest to lowest are: A, B, and C. They represent
the ' fiie'sability to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt and concrete . A
tire marked C may have poor traction performance .
Warning: Thetr.ction grade assigned to this tire is based on braking (straight-ahead) traction tests and· doellnot include cornerillg (turning) tractlon.
TEMPERATURE -A, B, C
The ·temperature grades are A (the highest), B, andC, representing the tire's
resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditio 'ns on a specified indoor laboratory test wheel.
Sustained 'high temperature can cause the material of the tire to degenerate
and reduce tire
life, and excessive temperature can lead to sudden tire failure .
The grade C corresponds to a level of performance which all passenger car
tires must meet under the Federat Motor Vehicle Safety Standard No.
109 . Grades B and A represent higher levels of performance on the laboratory test
wheel than the minimum required by law.
Warning: The
temperature grade for Ihis tire is established for a tire that
is properly inflated and not overloaded. Excessive speed, underinllaiion, or excessive loading, either separately or in combination, can cause heat
buildup and possible lire failure.

molded on the sidewalls of passenger car lires over Ihe nexl several years
according to a schedule established by the Nalional Highway Traffic Safety Administration and the tire manufacturers.
While the lires available as standard or optional equipment on General
Motors
vehicles may vary with respect to these grades, all such tires
meet General Motors performance standards and have been approved
for useon General Motors vehicles.
All passenger car tires must conform to Federal safety requirements In addition to these grades.
You should
replace your tires when:
I. The lires are worn to a point where 1.6 millimeters (2/32 inch) or less
tread remains, or the cord or fabric
is showing . To help you detect this,
your tires have built-in tread wear indicators that appear between the tread
grooves when the tread is 1.6 millimeters (2/32 inch) or less. When the
indicators. appear in two or mors adjacent grooves at three. spots around Ihe tire, the tire should be replaced.

2. The tread or sidewall is cracked, cut or snagged deep enough to expose
the cord or fabric.
3. The tire has a bump , bulge or split.
4. The tire has a puncture, cut, or other injury that can't be correctly repaired
because of the size or location of the injury.
Wheel Replacement
Damaged wheels must be rePlaced. For example, replace wheels if they are bent, cracked , or heavily rusted , or if _ wheel nuts ohen become loose. Also
replace wheels which leak air (except" some aluminum wheels which can be repaired-- see your authorized dealer).
Do not use bent wheels which have been -straightened, and do not use inner
tubes in leaking wheels designed for tubeless tires. Such wheels may have
structural damage
and could fail without warning. When replacing wheels for
any reason, the
new wheels should be equal in load limit, diameter, width,
offset. and mounting configurations to those
originally installed on your vehicle.
