1993 OLDSMOBILE SILHOUETTE spare tire

I Tires
We don’t make tires. Your new vehicle
comes with high quality tires made
by a
leading tire manufacturer. These tires
are warranted by the tire manufacturers
and their warranties are delivered with
every new Oldsmobile.
If your spare tire
is a different brand than your road tires,
you will have a tire warranty folder from
each
of these manufacturers.
Poorly maintained and improperly used tires are dangerous.
I * Overloading your tires can cause averheating as a result of bo much
fiction. You could have an air-out and a serious accident. See the Index
under Loading Your Wick.
Underinflated tires pose the same danger as overloaded tires. The resulting
accident could cause serious injury. Check all tires frequently to maintain
the recommended pressure. Tire pressure should be checked when your
tires are cold.
Overinflated
tires are more likely to be cut, punctured, or broken by a
sudden impact, such as when you hit a pothole. Keep tires at the
recommended pressure.

Inflation-Tire Pressure
The CertificatiodTire label which is on
the rear edge of the driver’s door shows
the correct inflation pressures for your
tires, when they’re cold. “Cold’’ means
your vehicle has been sitting for at least
three hours or driven no more than a
mile. Don’t
let anyone tell you that
underinflation
or overinflation is
all right. It’s not. If your tires don’t
have enough air (underinflation),
you can get:
Too much flexin1
Too much heat
Tire overloadine
Bad wear
Bad handling
Bad fuel economy.
If your tires have too much air
(overinflation), you can get:
Unusual wear
Bad handling
Rough ride
Needless damage from road
I
When to Check:
Check your tires once a month or more.
Don’t forget your compact spare tire. It
should be at
60 psi (420 kPa).
How to Check:
Use a good quality pocket-type gage to
check tire pressure. Simply looking at
the tires will not tell you the pressure,
especially if you have radial tires-
which may look properly inflated even if
they’re underinflated.
If your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.

Buying New Tires
To find out what kind and size of tires
you need, look at the Certification/Tire
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. 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.)
