1993 BUICK LESABRE tire size

The anti-lock brake system warning light may also come Traction Control System Warning Light
on when you are driving with a compact spare tire. If (Option)
this happens, the light means you won’t have anti-lock
until you replace the compact spare with a full-size tire.
If the warning light stays on after you replace the
compact spare with a full-size tire, or
if it comes on
again when you’re driving, your Buick needs service.
TRACTION
OFF
The “TRACTION OFF”
warning light means that
the system is not working.
This warning light may
come on for the following
reasons:
0 If your transaxle overheats, the traction control
system automatically shuts
off for about three
minutes. The warning light will come on and stay on
during that time.
.
0 If your brakes overheat, the traction control system
will
go off and the warning light will come on until
your brakes cool down.
If the “TRACTION
OFF” warning light comes on and
stays on for an extended period
of time, your vehicle
needs service.

Weight of the Trailer Tongue
The tongue load (A) of any trailer is an important
weight
to measure because it affects the total capacity
weight
of your vehicle. The capacity weight includes the
curb weight
of the vehicle, any cargo you may carry in
it, and the people who will be riding in the vehicle. And
if
you will tow a trailer, you must subtract the tongue
load from your vehicle’s capacity weight because your
vehicle will be carrying that weight, too. See “Loading
Your Vehicle” in the Index for more information about
your vehicle’s maximum load capacity.
A
If you’re using a “dead-weight” hitch, the trailer tongue
(A) should weigh 10% of the total loaded trailer weight (B).
If you have a “weight-distributing” hitch, the trailer
tongue
(A) should weigh 12% of the total loaded trailer
weight (B).
After you’ve loaded your trailer, weigh the trailer and
then the tongue, separately, to see
if the weights are
proper. If they aren’t, you may be able to get them right
simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for
cold tires. You’ll find these numbers on the Certification
label at the rear edge of the driver’s door (or see “Tire
Loading” in the Index). Then be sure you don’t go over
the
GVW limit for your vehicle.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by, and rough roads are a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0 If you’ll be pulling a trailer that, when loaded, will
weigh more than
2,000 pounds (900 kg), be sure to
use a properly mounted, weight-distributing hitch
and sway control
of the proper size. This equipment
is very important for proper vehicle loading and
good handling when you’re driving.
191

Compact Spare Tire
Although the compact spare was fully inflated when
your vehicle was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi (420
Wa). The compact spare is made to go up to 3,000 miles
(5000 km), so you can finish your trip and have your
full-size tire repaired or replaced where you want. Of
course, it’s best
to replace your spare with a full-size tire
as soon as
you can. Your spare will last longer and be in
good shape in case you need it again.
Your anti-lock brake system warning light may come
on
when you are driving with a compact spare. See
“Anti-Lock Brake System Warning Light” in the Index. Don’t
use your
compact spare on some other vehicle.
And don’t mix your compact spare or wheel with other
wheels or tires. They won’t fit. Keep your spare and its
wheel together.

A CnUTION:
Storing a jack, a tire, or other equipment in the
passenger compartment of the vehicle could
cause injury. In a sudden stop or colllsian, loose

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 for the tires on your vehicle. It also gives you
important 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, found 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
176 pounds (80 kilograms)
in your trunk .

c:
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.
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 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 a
“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.
TREAD WEAR INDICATORS
You need a new tire if:
you can see the indicators at three 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.
258

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.
It’s all right to drive with your compact spare,
though. It was developed for use on your vehicle.

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.)
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,
a tire graded 150 would wear one and a half
(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 significantly from the norm due to variations
in driving habits, service practices and differences in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. 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 grade
C corresponds to a level of performance

‘A CAUTION:
0
Using the wrong replacement wheels, wheel
bolts,
or whwl nuts on your vehicle can be
dangerous. It could affect the braking and
handling
of your vehicle, make your tires lose air
and make you lose control.
You could have a
collision in which you or others could be injured.
Always use the correctwheel, wheel bolts, and
wheel
nuts for replacement.
NOTICE:
I
The wrong wheel can also cause problems with
bearing life, brake cooling,
speedometerlodometer calibration, headlight
aim, bumper height, vehicle ground clearance,
and tire

’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 anew
GM original
