Rust or dirt on the wheel,
which it
is fastened, can make the wheel nu
become loose after a time. The wheel could
come

change
a wheel, remove any rust or dirt fro1
the places where the wheel attaches to the
vehicle. In an emergency, you can use
a cloth or
a paper towel to
do this; but be sure to use a
scraper or wire brush later, if you need to, to get

Compact Spare T,ire
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
Pa). The compact spare is made to g6 up to 3,000 miles
(50,OO 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 ti\
re
as soon as you can. Your spare will last longer and be in
good shape in case you need it again.
Your anti-1ock.brake system warning light -may come on
when you are driving with a compact spare. See
“Anti-Lock Brake System Waming 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.

possible. Don’t spin the wheels above 35 I h

After the tires have beers rotated, adjust the front and
rea inflation pressure as shown on the Tire-Loading
Information label. Make certain that all wheel nuts ax9
properly tightened. See “Wheel Nut Torque” in the

Index.
A CAUTION:
Rust or diir on a wheel, or on the parts to which
it is fastened, can make wheel nuts become
loose after a time. The wheel-could come off
‘and cause an accident. When you change a

is to.

enough to show cord or fabric.
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 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.

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
