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 (5 O00 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 the
Idex
under Anti-Lock Brake System Warning
Light.

through
an automatic vehicle wash I

of
your vehicle.

Loading bur Vehicle
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
sticker, also 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
132 lbs. (60 kg) in your trunk.

When lt’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear
indicators, which will appear when your
tires have only
2/32 inch (1.6 mm) or
less of tread remaining.

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
I tires.

CAUTION
A
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 wheels.
It's
all right to drive with your compact
spare, though. It was developed
for limited use
on your vehicle.
I
Grding
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%) 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.
