1993 BUICK ROADMASTER tires

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 nu-mber will be followed. by a “MS”
(for mad 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.
‘t
A CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different siz
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
cows
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 (if
you have one). It

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 govement test course. For
I

Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
In most cases, you will not'need to have your wheels
aligned again. However, if
you notice unusual tire wear
or your vehicle pulling one way
or the other, the
alignment may need to be reset.
If you notice your
vehicle vibrating when driving
on a smooth road, your
wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked .I or badly rusted.
If wheel nuts keep coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced.
If the wheel leaks air
out, replace it (except some aluminum wheels, which
can sometimes be repaired). See. your Buick dealer
if
any of these conditions exist.
Your dealer will how the kind
of wheel you need.
Each new wheel should have the same load carrying capacity, diameter, width, offset, and be mounted the
same way as the one it replaces.
If you need to replace-any of your wheels, wheel bolts,
or wheel nuts, replace them only with new
GM original equipment parts. This
way,
you will be sure to have the
right wheel, wheel bolts, and wheel
nuts for your Buick
model.
/! CA-TION:
Using the wrong replacement wheels, wheel
bolts, or wheel 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
