Tire Size
The following examples show the different parts of a
tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a metric tire sizing system. The letter P as the
rst character in the tire size means a passenger
vehicle tire engineered to standards set by the U.S. Tire
and Rim Association.(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 75, as shown in item C of the
illustration, it would mean that the tire’s sidewall is
75% as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The letter
R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:The service description
indicates the load range and speed rating of a tire. The
load index can range from 1 to 279. Speed ratings
range from A to Z. Passenger (P-Metric) Tire

When rotating your tires, always use one of the correct
rotation patterns shown here.
If your vehicle has a compact spare tire or a spare tire
that does not match your vehicle’s road tires and
wheels, in size and type, do not include the spare in the
tire rotation.
After the tires have been rotated, adjust the front and
rear ination pressures as shown on the Tire and
Loading Information label. For the location of the tire
and loading information label seeLoading Your Vehicle
on page 4-50. Make certain that all wheel nuts are
properly tightened, see “Wheel Nut Torque” under
Capacities and Specications on page 5-107for the
proper wheel nut torque specication.
{CAUTION:
Rust or dirt 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 wheel, remove any rust or dirt from
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 all the rust or dirt off. See “Changing a Flat
Tire” in the Index.
5-66

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.
{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. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It’s all right to drive with your
compact spare (if you have one). It was
developed for use on your vehicle.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
5-68

Tire Chains
{CAUTION:
If your vehicle has P225/75R15, P265/75R15 or
P235/50R17 size tires, do not use tire chains.
They can damage your vehicle because there
is not enough clearance. Tire chains used on a
vehicle without the proper amount of clearance
can cause damage to the brakes, suspension
or other vehicle parts. The area damaged by
the tire chains could cause you to lose control
of your vehicle and you or others may be
injured in a crash.
Use another type of traction device only if its
manufacturer recommends it for use on your
vehicle and tire size combination and road
conditions. Follow that manufacturer’s
instructions. To help avoid damage to your
vehicle, drive slowly, readjust or remove the
device if it is contacting your vehicle, and
don’t spin your wheels.
If you do nd traction devices that will t,
install them on the rear tires.Notice:If your vehicle has a tire size other than
P225/75R15, P265/75R15 or P235/50R17, use
tire chains only where legal and only when you
must. Use chains that are the proper size for your
tires. Install them on the tires of the rear axle. Do not
use chains on the tires of the front axle. Tighten
them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain
manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten
them. If the contact continues, slow down until
it stops. Driving too fast or spinning the wheels with
chains on will damage your vehicle.

14. Tilt the tire retainer at the end of the cable and pull
it through the wheel opening. Pull the tire out from
under the vehicle.
15. If the cable is hanging under the vehicle, turn the
wheel wrench clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using
the hoist assembly until it has been replaced.
To continue changing the at tire, see “Removing the
Flat Tire and Installing the Spare Tire” earlier in
this section.
Spare Tire
Compact Spare Tire
Your vehicle may be equipped with a compact spare
tire. Although the compact spare tire was fully inated
when your vehicle was new, it can lose air after a time.
Check the ination pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicle, you
should stop as soon as possible and make sure
your spare tire is correctly inated. The compact spare
is made to perform well at speeds up to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can nish your trip and have your full-size
tire repaired or replaced where you want. For heavy
payloads or towing, and for low traction or
four-wheel-drive conditions, repair or replace the
full-size tire, and reinstall for best performance. 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.
Notice:When the compact spare is installed, don’t
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught
on the rails. That can damage the tire and wheel,
and maybe other parts of your vehicle.
Don’t use your compact spare on other vehicles.
5-93

And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t t. Keep your spare tire
and its wheel together.
Notice:Tire chains won’t t your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.
Full-Size Spare Tire
Your vehicle may be equipped with a full-size spare tire,
which, when new, was fully inated. A spare tire,
whether compact–size or full–size, may lose air over
time, so check its ination pressure regularly. See
Ination - Tire Pressure on page 5-64andLoading Your
Vehicle on page 4-50for information regarding proper
tire ination and loading your vehicle. For instruction on
how to remove, install or store a spare tire, see
Changing a Flat Tire on page 5-74.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare is
correctly inated. Have the damaged or at road
tire repaired or replaced as soon as you can and
installed back onto your vehicle. This way, a spare tire
will be available in case you need it again.
Don’t mix tires and wheels of different sizes, because
they won’t t. Keep your spare tire and its
wheel together.
Appearance Care
Cleaning products can be hazardous. Some are toxic.
Other cleaning products can burst into ames if a match
is struck near them or if they or get on a hot part of
the vehicle. Some are dangerous if their fumes
are inhales in a closed space. When anything from a
container is used to clean the vehicle, be sure to follow
the manufacturer’s warnings and instructions. And
always open the doors or windows of the vehicle when
cleaning the inside.
Never use these to clean the vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous — some more than
others — and they can all damage the vehicle, too.
