Alignment and B.alance
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 m ore information.) Ball joints have built-in wear indicators,
and some movem ent in th~ joint s is normal. ' Improper alignment will not cause
the
vehicle to vibrate. However, improper toe alignment will cause the tires to roll
at an angle which will result in faster tire wear. Incorrect caster or camber
alignment will cause your tires to wear unevenly, and can cause the vehicle to
"pull" to the left or right.
Proper tire balan cing provides the best riding comfort and helps reduce tire tread
wear. Out--of-balan ce tires -can .cause annoying vibration and uneven tire wear such
as cupping and
flat spots.
Traction
A decrease in driving. cornerin g, and braking traction occurs when water, snow,
ice, gravel ,
or other material is on the road. Driving practices and vehicle speed
should be adjusted to the road condition~.
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
l oss
of traction, vehicle control, and stopping ability.
To reduce the chance of traction loss, follow these tips:
I. Slow down during rainstorms or when roads are Slu shy .
2. Slow down if road has standing water or-pUddles.
3. Replace tires when tread wear indicators are showing.
4 . Keep tires properly inflated.
If your vehicle has TPC radial.tires (see "Tire Replacement" in this section), your
lir es were design ed to
provide _ better snow tracti on than -bias or bias-belled tires
without snow treads. However , iF . yo u use conventional snow tires. be sure they
are the same size. loa d range, and construction type (bias, bias belted,
or radial)
as your other tire

Use of chains may adversely affect your vehicle's handling. When using chains : (I) adjust speed to roa d conditions, (2) avoid sharp turns, and (3) when possible,
avoid
locked-wheel braking . In addition, to help preve nt chain -damage to your
vehicle:
• Install the chain s on the front tires as tightly as possible, then tighten again
after driving 114 to 1/2 mile (0 .4 to 0 .8 kilometer). The use of chains on the
rear tires is not recommended; the chains may contact and possibly damage
the
car. If you intend to use chains on the rear tires , m ake certain there is
enough clearance.
• Do not exceed 45 mph (76 km /h), or chain manufacturer's speed limit, jf
lower.
• Drive in a restrained manner and avoid large bumps. potholes, severe turns
and other maneuvers which could cause the tires to bounce up and down .
• Follow any other chain manufacturer's instructions which do no t disagre e
with the above.
If you purchase tire chains for your Citation, make sure they are designated as
SAE Class "S" type chains. U se of other types of chains may cause damage to
your car.
Spare Tire
For the use and installation of your spare tire, see "In Case of Emergency" Section
3
of this manual.
Tire Replacement
CAUTION: Do not mix different tire construction types of tires (such as rediel, bias, and bias.belted) on your vehieleexcept in emeruencies, because your vehicle's handling could be affected and may result In loss of contrOl. This caution does not a~y to 8 stowaway. compact,. or temporary spar. tlr. fumished with your vehtcle.
On most ve hicles originally equipped with radial tires, you will find a TPC Spec.
No. (Tir e Performan ce Criteria Specification Numbe-r) molded into the tire
sidewall ne
ar the tire size marking. This shows that the tire meets rigid size and
performanc e standards which were developed -for your vehicle. The TPC Spec.
No. assures a proper combination of endurance, handling, load capacity, ride, and
traction on wet , dry, and sn o w covered surfaces . When you re place your tires with
tires having the same
TPC Spec. No., your new tires will be co mpatible with your
vehicle.
When replacing tires with those not having a
TPC Spec. No., you should use the
same size, load range ,
and construction type (bias, bias-belted, or radial) "as the
original tires on your 'vehicle. Although it is not generally recommended. some
alpha-size and metri c- size tires can
be interchanged (for size equivalen cy contact
your Chevrolet dealer or a lire 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 . If replacing only a single tire,
it should be paired on the same axle with the least worn tire of the other three.

Downloaded from www.Manualslib.com manuals search engine UNIFORM TIRE QUALITY GRADING
The following information· relates to the tire grading system developed by the
National Highway Traffic
Safety Administration which will grade tires by tread wear, traction· and temperature performance:
TREADWEAR
The tread wear 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 half(l-1I2) 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
significantly from the norm due to variations in driving habits, service practices
and differences in road characteristics and c1imate.
TRACTION -A. B. C
The. traction grades, from highest to lowest are A, B, and C, and they represent
the tire's ability 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: The traction grade assigned to this tire is based on braking
(straight·ahead) traction tests and does not include cornering (turning) traction.
TEMPERATURE -A. B. C
The temperature grades are A (the highest), B, and C representing the tire's
resistance to the generation
of heat and its ability to dissipate heat when tested
under controlled conditions 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 gradeC
corresponds to a level of performance which all passenger car tires must meet
under the Federal 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 this tire. is established for a tire that is
properly inflated and neit overloaded, Excessive speed, underinflation, or excessive
loading, either separately or in combination, can cause heat buildup and possible
tire failure,
At this time your tires mayor may not have a grade. These grades will be molded
on· the sidewal1s of passenger car tires over the next several years according to
a schedule established by the National Highway Traffic Safety Administration and
the tire manufacturers.
While the tires8vailable as standard or optional equipment on
General Motors vehicles may vary with respect to grade. all such tires meet General Motors performance standards and have been
approved for use on General Motors vehicles.
All passenger car tires must conform to Federal safety requirements
in addition to these grades.
You should replace your tires when ...
1. They are worn to a point where 1.6 millimeters (2/32 inch) or less tread
remains,
ot cord or fabric is showing.
